    Mastersound, noen som kjenner til disse?

    Mastersound kommer ursprungligen från Vicenza i Italien.

    Noen som kjenner til disse Italienske rør forsterkerene? pro´s & con´s og evnt linker?

    Tenker i første hand på disse to forsterkerene:

    Compact 300B
    Integrerad förstärkare/slutsteg på 2*15 watt med 1 st 300B rör i parallell single end klass A per kanal, helt utan negativ återkoppling. Förstegsrören är dom musikaliska ECC82 rören och drivrören är 6SN7GT. Förstärkaren har tre ingångar och fjärr till volymen samt en direktingång om du vill använda den som ett slutsteg. Storleken är 54 X 30 X 27 cm och vikten är 27 kg.




    og/eller...

    Compact 845
    Integrerad förstärkare/slutsteg på 2*30 watt med 1 st 845 rör i parallell single end klass A per kanal, helt utan negativ återkoppling. Förstegsrören är dom musikaliska ECC82 rören och drivrören är 6SN7GT. Förstärkaren har tre ingångar och fjärr till volymen samt en direktingång om du vill använda den som ett slutsteg. Storleken är 54 X 30 X 27 cm och vikten är 33 kg.

    Heisann.
    Ute etter noe glødende til nye høyttalere ? Art Dudley testet en integrert 300b i stereophile for en tid tilbake. Han likte den veldig godt. Ta en titt i arkivet deres, så finner du den.

    Takker! fikk meg en kjapp lytt på compact 845 igår, ikke avskrekkende, i det hele tatt til tross for grøt i hodet og tette øreganger, denne tar jeg muligens hjem på test når det stunder ...

    Snakkes!

    Våger du deg alikevel på en lydsignatur beskrivelse?, pro´s og con´s? tar nok som nevnt compactén hjem på test her etterhvert, men er også sugen på å teste compact 300b, dessverre er det relativt få (om noen) slike i landet (Sverige) så det kan bli vanskelig med hjem test.....

    Å sammenlikne 300B og 845 blir som å sammenlikne epler med ...
    -umulig.
    Men jeg vil tro at nyere modeller vil være greie uansett..

    Hei igjen...

    Tenkte vel her mer generellt på hva den 845én du har på rep hadde for signatur, er ikke noe videre bevandret i verken 845 eller 300B, så derav kommentaren om den compacte 300B, som jeg gjerne skulle hørt også for å se hva som passer meg best...du har pm .....

    Hvordan smaker et eple? Vin? Pølse? Hvor langt er et tau?
    Umulig å si, og jeg prøvde ikke 845 i noe optimalt oppsett.

    Hardt, søtt, surt, mykt, fast, sur, fyldig, frisk, rund, stram, fett, kjøtt, fast med knekk garanti, tauet er så langt man bestemmer det, ikke umulig å beskrive i helt generelle termer, detaljene og resten er jo opp til lytteren å subjektivt bedømme

    Mastersound, noen som kjenner til disse?

    av Garret Hondo (SfCI), 2007:

    I'd met Lorenzo Sanavio, one of two brothers who own Mastersound, at CES in Las Vegas early this year, then again at Top Audio in Milan (Italy), where I heard a system featuring Mastersound's new 845 monoblocks--the Pf 100 Limited Edititon ($39,995/pr.). With wires handmade at Mastersound, gain through the new Mastersound PH L5 pre ($4,895 w/ MM phono), and speakers designed by Lorenzo, the Pf 100 system sounded ultra fast and detailed with a deep and wide soundstage. It seemed to me the medium-sized hotel room was too small for the capabilities of this system, sourced by a North Star Sapphire CD player. It played CDs (mine) by a Charles Mingus quintet, Sarah Vaughan backed by musicians from the Count Basie Orchestra, and Le Concert d' Astree performing Mozart's "Mass in C Minor" equally well. Here in Vicenza, Lorenzo, who is a schoolteacher by day, drove me out to his factory in a big Volvo wagon. "I need this to haul equipment," he said. "But, for Top Audio, we needed two cars--my brother Luciano is returning later with the second car." We wended through circle intersections, entered an expressway and wove our way through late afternoon traffic around a long oval ramp, then shot out to through suburbs, then surface streets to the semi-industrial area where Mastersound had its small factory. It was a small two-story building amidst modest residential villas, their walls ivied and gates vined with bougainvillea. We went upstairs, above the office on the first floor, to the shop on the second.



    From the landing, I could see that packed inside the 12m X 31m space were five long tables, each of which supported rows of amp chassis, test equipment, circuit boards, transformers, and boxes filled with tubes, knobs, capacitors, and resistors. "We have here only three workers," Lorenzo said, glowing with Italian charm. "Of all Mastersound, there is FIVE people only, he said, "With my brother--who is engineer--and me." He swept his arm like a maitre de and invited me to enter the shop floor. Then, he pointed to each table, identifying in succession the various amps currently in production--the Compact 300b ($5,795), the Compact 845 ($5,795), the EL-34-powered Due Venti ($2,995) and Due Trenta ($3,395), and the 300B S.E. ($6,095). I asked him what the relationship was between VAIC amps and Mastersound amps, as I'd read that the VAIC, which I own, was designed in the old Czech Republic but assembled by Mastersound.



    http://www.sonusfaberclub.com/upload...P1010705_1.jpg

    "Is the same amp," Lorenzo said, "VAIC 300B SE is Mastersound 300B SE--no difference in circuit or transformer. Only cosmetic--the side and front, the name--is different."

    I was delighted to hear this, of course. And I'd suspected such, as their layouts were exactly the same. This was great news. Lorenzo told me that the 300B SE amp stereo amp was the last designed by his father Cesare Sanavio and that all other amps in current production were the designs of his brother Luciano, an electrical engineer and graduate of the University of Padua. Essentially, there are two lines of Mastersound--the Cesare-designed line and the Luciano-designed one. Taken together, they amount to seven SET integrated amplifiers, three monoblock amplifiers, and the new PH L5 pre. Eleven top-quality amplifiers in all.

    It was Luciano who dreamed up the new circuitry that became the Compact 300b and Compact 845--zero-feedback SET integrateds. He also designed the 845 Reference integrateds ($12.495), new pre, and new Pf 100 Limited 845 monoblocks, which Lorenzo thought the most powerful SET amps around at 117W per channel--all in Class A. All Mastersound amps are zero feedback, Class A designs, in fact. Each amp is created in stages, Lorenzo said--a day weaving its transformers, a day assembling and soldering the boards, another day for preparing total assembly. Then, depending on the amp, complete assembly may take one day for the Due Venti or as many as two days for an 845 Reference stereo amp. Testing involves different protocols for each amp--some taking a half-day, others more than a day. Finally, there is the burn-in of each amp, lasting another full day. From weaving the transformers to burn-in, the manufacture of an amp may take a full week to complete and involve each of Mastersound's staff of five people.






    Besides their designs, perhaps what was most special about Mastersound was that they made their own transformers right there in the shop. Lorenzo took me to a back cranny where there were two ancient winding machines sitting side-by-side on a short table. Their chassis were so worn and chipped, they looked like they'd been painted a dirty grey camouflage. Behind them was a bin full of shining copper wires of different gauges still on their spools. He picked one of them up and said, "We make transformers out of Litz wire so soldering is not possible. You cannot cross the wires in winding, so this must be carefully done." He mentioned that the number of windings per wire was a secret, that there were numerous combinations of windings that altered the magnetics, and that the wire-counts were very high. Finally, the windings are encased in a stone and resin mix that make copying their transformers impossible. If anyone attempted to cut into them to diagnose their secret, the rocks would cause so much mangling that the transformers would be destroyed without exposing their formulas. Finally, the mass and densities of the transformers is so high, the average weight of a Mastersound amp is around 75 pounds, making them very difficult for any thief to steal. "You cannot carry this amp very far very fasst," Lorenzo joked.







    We finished the tour when Luciano arrived just as the sun began slanting through the doorway and windows of the shop. It was already early evening. Lorenzo asked his brother to rig up a demonstration on the test bench, measuring the flatness of response of the new Mastersound PH L5 pre (it has 4 line-level inputs and an MM phono built in, frequency response: 1 Hz / 100 kHz – 0dB). After the usual folderol, switching wires and rigging the contacts, what I saw was a series of measurements that showed the pre's response was amazingly flat at all frequencies. The waveforms jittered and oscillated, looking like the Intro to an episode of "The Outer Limits," but they never made excursions past two parallel horizontal lines--one near the top of the scope and one nearer the bottom. "You see," Lorenzo said, waving a flat palm parallel to the floor, "The PH L5 response is completely flat."



    After the factory tour, Lorenzo took me on a rapid and merry sight-seeing ride through the byways of Vicenza. He drove me up walled wagon-roads to a sequestered private villa on a hill and then down a broad public boulevard to a building called "The Rotunda." Both were designed by Andrea Palladio, famed 16th century architect and adopted son of Vicenza. At sunset, we drove up a broad, sloping, tree-lined avenue to Mount Berico for a view of the city bathed in early evening mist. Our quick trip ended up at the home of Emmanuele Perici, Lorenzo's long-time friend whose large villa home was the de-facto and luxurious Mastersound listening room. Mr. Perici is an attorney who owns nearly a dozen Mastersound amps--seven in one room and four others in smaller rooms throughout his spacious villa. We listened for nearly three hours to a system assembled by Lorenzo around Mastersound 845 monoblocks and custom-built Mastersound three-way speakers Lorenzo had designed just for Perici. He played audiophile disks of jazz and Italian pop, then a CD-R of a live recording from an outdoor concert former Pink Floyd bassist Roger Waters gave at the Verona amphitheater. The music flowed along with conversation, and I found myself admiring the dramatic, operatic effects of Waters's music, altogether new to me. Soundstage and imaging were superb. Perici admitted, though, that he'd gotten so far into the minute capabilities of his system, that it was hard for him to let himself to listen uncritically anymore, that he focussed on flaws in the recordings, on tape hiss and microphone distortion, on shortcomings (imagined or real) in his system. I could well understand that, as, when they invited me to play my own reference CD (Mozart's "Mass in C Minor") on this magnificently transparent system, I could hear that the soprano soloists were slightly over-miced, that the tenor choir was as well, and that there was a minor and evanescent tape-hiss. Lorenzo and he, out of predominantly Mastersound reference-level equipment, had assembled a mighty and refined system that exposed any and all flaws in one's source material.







    We finished the evening with a patio dinner at a restaurant about a hundred yards uphill from Emmanuele Perici's door and near the lookout of Mount Berico. Lorenzo wanted us to see the misty lights of Vicenza while we dined. With a bottle of vino rosso from Veneto and a primi course of tagiiatelle nere con seppie (a pasta dish with cuttlefish and fresh-made noodles fat as Chinese chow fun, blackened with squid-ink), it was a relaxing and delicious ending to a long, intense day making new friends and full of audio illuminations.

    Meget gode forsterkere dette her, har selv annskaffet en mastersound 845 compact, trodde kanskje den skulle få problemer med å driv mine JBL Array 800(88 db) men den
    hadde ingen problemer med dem. Men jeg har stor tro på at høytalere med ennå høyere følsomhet så blir det enda bedre om man må dra på virkelig høyt.

    Det kan jeg skrive under på. Har Compact selv og de tar ballegrep på mine store Tannoy DC10T høyttalere. DC10T har en følsomhet på 92dB og tydeligvis en ganske snill impedansekurve, men det rapporteres til stadighet at de trenger heftig forsterkeri for å synge. Compact driver de til langt over 100dB i min stue på ca 40kvm uten å hikste. Det er vel jeg og akustikken som gir oss før forsterkeren.

    På Compact har du mye å hente med rørbytte. Anbefaler deg å teste ut litt og spesielt med inngangsrørene.

    Ja det er virkelig imponerende hvor stort denne forsterkeren spiller, veldig stort og fyldig lydbilde med ett nytt lag med detaljer i lydbildet.
    Hvilke rør har du valgt som inngangsrør?

    Spiller nå for tiden på siemens e82cc. Syntes det gir en enorm åpenhet og romfølelse. Har også prøvd mazda/cifte, mullard cv4003 og flere versjoner av rca. Siemens og mazda er de som har falt best i smak her i heimen.
