Kult prosjekt!
30 Cerwin Vega diskanthøyttalere og to 24-tommers Cerwin Vega-subwoofere, er ikke akkurat hva jeg forbinder med god lyd :-\
Hahaha, stilig med discokule i taket, tipper han er kongen den dagen han kommer på gamlehjemmet!

Tviler dog på at du kan sammenligne dette med ordinære type CW type høyttalere.janly skrev:
Det er hva jeg kaller ren skjær idioti....
holde på så lenge , og bli så urgammal at en ikke hører en damn shit......for så å være fornøyd=?
Horn er greit nok det ( for det må jo til) men hva med Cerwin vega sakene da =? er det no tess til slik bruk( beklager min uviten om dette er bra)
.....uansett , å bruke hele livet på å bygge noe slikt , for å knappt nok ha hørsel inntakt når det først funker.....ja det for meg virker helt på trynet....
De gærne harre gått. ;D

Han hadde jo et anlegg når han var 15 også. Tror ikke du han har hørt på musikk og drevet med hifi hele livet?
Artikkelen sier han er fornøyd nå. Tipper dog han har vært fornøyd tidligere også.

Så du mener man bør kutte ut hifi når man blir gammel?
Artig med så dedikerte entusiaster. Minner meg litt om han bygde disse enorme hornsubwooferene i gulvet. Han har sikkert hatt det mye morro på veien, og det er jo litt av meningen. Mon tro hvordan lyden er. Umiddelbart (uten å ha lest artikkelen) kan det virke som om han har først og fremst fokusert på å bygge høyttalere inn i rommet, ikke selve akustikken i rommet (?).
Har lest litt om Burwen's Bobcat, men at han også har et anlegg som dette visste jeg ikke.
Slett ingen gal amatør dette her. Iflg. burwenbobcat.com stod han bak Chello sin gamle Audio Palette for Mark Levinson. De har også samarbeidet ifbm. Bobcat-software under ML sin Red Rose paraply. Ganske omdiskutert for en tid siden. Oki...litt gal da

Kult at noen tørr å ta den helt ut og gå sine egne veier
Slett ikke , men man bør kanske få litt mere brukertidmed sakene , etter mitt syn , hvis man som annonsen sier har holdet på så lenge , får vi håpe at det i deler i allefall har spillt mere eller mindre flere ganger før.slowmotion skrev:

sjansen er overhengende for at jeg har har hatt en vanvittig samling hi-fi når jeg dauer....er jo pågo vei allerede.
I motsetning til deg , søker jeg etter nytt og bedre , mens du tviholder på det samme.
Begge veier kan selvsagt gi god lyd forutsatt at den som tviholder har funnet sin greie.
Helt enig....Jeg har og funnet min greie.....det blir Lowter her for ganske lang fremtid er jeg redd.
Jeg forsøker nå med cary 300b på disse , veldig bra men noe støy.
Quicksilverne er på ingen måte parkert av carys 300b blokker,.

Do I need expensive vacuum tube power amplifiers?
No!!!!! AUDIO SPLENDOR can save you a lot of money by equalizing your speakers much better than using the high output impedance of expensive,
low-feedback, vacuum tube amplifiers. Instead buy low distortion semiconductor amplifiers that have a lot of feedback and far more power output.
During my 60 years of designing circuits I designed a lot of vacuum tube, transistor, and switching power amplifiers and know how each performs. In the
1950's I designed the lowest distortion vacuum tube amplifier ever, the Krohn-Hite UF-101. It was rated at 50 Watts, 0.005% total harmonic distortion, 50
dB of negative feedback, and it sold in small quantities as a laboratory instrument for 20 years. Today I wouldn't take a vacuum tube amplifier as a gift.
Why?
What you are really buying is not quality amplification but a high distortion equalizer. The lack of feedback in many of today's tube amplifiers gives the
amplifier high distortion and a high internal output impedance, typically in the range of 1 to 5 ohms. At some frequencies such as the fundamental cone
resonance, and crossover frequencies between drivers, the load impedance of the speaker rises. The voltage divider effect delivers more signal to the
speaker terminals at these frequencies. With some amplifier-speaker combinations the effect on frequency response is very pleasing.
This load impedance effect was epitomized in the July, 2004 Stereophile review of the world's most expensive amplifier, the $350,000/pair Wavac SH-833,
by Michael Fremer with measurements by John Atkinson, page 73. The curves clearly show up to 2 to10 dB of bass boost at 80 Hz depending upon the
load impedance. The measured distortion is shameful for even the cheapest amplifier. A vacuum tube amplifier should really be regarded as a nice piece
of furniture with wires, that glows in the dark. Use a real equalizer to improve the frequency response of your speakers!
Equalizing your speakers is not enough. Any fixed frequency response system may optimally balance the tone on about 1 in 500 pieces of available
program material. You need really flexible multichannel program equalization to balance all the rest.
In my own sound system for 30 years I used Phase Linear 400 power amplifiers that I redesigned for lower noise, -115 dB re 200 watts, and reduced bias
drift. The 34 channels each drive 1 woofer, 1 mid-range horn, or 9 or 12 of the 30 tweeters in each 13 foot speaker horn. With the 4-way electronic
crossover the equivalent sound level available is that of a single 20,000 watt monoblock. Before purchasing these amplifiers I compared one with my
Krohn-Hite UF-101 Ultra-Low Distortion Power Amplifier. The sounds were identical except that the Phase Linear 400 played louder before clipping.
In 2004 after tiring of repairing the Phase Linears whose transistors suffered thermal fatigue, I replaced them all, purchasing 19 QSC SRA1222 dual 200
watt amplifiers. I chose these amplifiers, after measuring one unit, for their 200 watts/channel, (all my speakers can handle), low internal impedance due
to high feedback, flat frequency response, low distortion, low noise (6 dB worse than my Phase Linears), high slew rate, switching power supply,
automatic gain reduction during clipping for reduced distortion, 3.5 inch rack panel size, 22 lb. weight, very low fan noise, and 3-year warranty. They cost
under $1000 each and for somewhat more money QSC offered up to 1800 watts/channel into 2 ohms in the same size. I cannot detect any change in the
sound. In 6 years of operation at 70 hrs/week, none have failed.
That is the sort of amplifier I suggest for you and there are plenty of other good amplifiers from other manufacturers in the professional area. And forget
expensive cables. They are inaudible furniture.

Ref: John Mazur
Most every equipment maker seems to claim their equipment is "World Class", "Reference", and "Sounds Like Analog". When Mark Levinson, The Man, made a similar claim about the Burwen Bobcat/Daniel Hertz Model 1 USB DAC/software combination, it sure got my attention. Mark Levinson embraces analog and SACD playback and there he was sticking his neck out. Even more bizarre was his claim that MP3s sounded like analog through the Burwen Bobcat/Daniel Hertz gear. Just how crazy was this? His partner in this, Dick Burwen, is an engineer and has numerous inventions in widely varying fields of electronics to his claim. (Check it out: http://www.burwenaudio.com/Biography.html) When Mark Levinson heard an MP3 played through a computer-based mastering system that Burwen was working on, he was amazed that it sounded so much like analog or pure DSD. From there the concept was born.

Dersom dette spiller i verdensklasse er jeg imponert i forhold til utstyret han bruker. Må si jeg er skeptisk. 19 QSC PA amper til under $1.000 pr stk og en haug med CV elementer. Ikke det at prisen betyr noe, men da kan det være at vi som bruker en haug med penger på rør amper tar feil :-\. I hverfall i følge denne selverklærte "guruen".

Fyren er nok noe mere en selverklært guru. Han jobbet trostsalt som rådgiver for Mark & Levinson og var med på og designe noen av de første forsterkerne deres, samt en haug med annet. Må da ikke ta det han sier alt for tungtjanly skrev:

Tror ikke man skal se seg blind på hva slags utstyr han bruker, men heller fokusere på implementeringen. Aner ikke hva slags kvalitet det er på de CV-diskantene han bruker, men når han bruker et array på 30 enheter pr kanal som er satt opp for riktig spredning virker det som, så er iallefall alle problemer ift forvrenging eliminert. Enhetene gjør sikkert det designeren har tenkt at de skal gjøre.janly skrev:
Jeg var også skeptisk til dette oppsettet til å begynne med, og syntes fyren virket som en tulling, men etter hvert som jeg har lest på siden hans og forsøkt å sette meg inn i tankegangen hans blir jeg bare mer og mer imponert. Tror nok likevel jeg ville valgt en litt annen retning selv om jeg skulle bygd noe så kompromissløst.
Det virker ikke som han bryr seg så mye om hornteori som har kommet etter han startet prosjektet på 60-tallet. Jeg vil nok skjenet litt til Tom Danley for å optimale integrasjon og tid/fase-problematikk og til Earl Geddes for å minimere diffraksjonsproblemer. Men det ville kanskje ført til andre kompromisser igjen... Holder en knapp på at han vet nøyaktig hva han driver med!
Stiller meg støttende til at equalizing, eller romkorreksjon om du vil, er fremtiden. Men intill folk lærer seg hvordan man virkelig skal stille inn noe slikt må vi nok kjøpe forsterkere med ferdiglagde "presets".
Føler at mine Nordost Heimdall kabler ikke var så gunstig priset likevel.
