Er litt på jakt etter en rør-forforsterker til min Audio Research VT-100mk3.
Har satt en øvre grense på rundt 25 for en forforsterker ny eller brukt, og den bør være rørbasert. Har sett litt på Ear modellene. Videre så liker jeg Prima Luna sin pre og da Audio Research sin SP16 og LS25 mk1 med 6922 rør.

Eneste jeg har hørt i mitt oppsett er SP16 som jeg hadde tidliger. En bra pre som jeg gjerne skaffer meg igjen.

Hvem av disse (eller andre) ville dere gått for?

Sonic EvaluationsThe VT100 Mk.III is more detailed and gives a more forward presentation then the older Mk.II version which has a more relaxed and tube like midrange. The Mk.III is a very revealing amplifier and will show up any harsh or unflattering front-end components in a flash. Be warned. It retains all of the tube virtues in it's harmonics and timbre but couples them with a more exact soundstage, never before seen from Audio Research. This amplifier is the primary product that has taken the company in a new direction. Being one of, if not THE first one of their products to utilize the 6H30 or 'Super Tube' to some. Spinning Eric Clapton's - 'Backless' album (RSO Records, 1978) the fine fragments of detail the Mk.III can show up is staggering. Not only is the sound full but the soundstage is wide also. It just makes you want to crank the volume to full, so enjoyable is the synergy of speed and rhythm. The top end is not harsh or fatiguing to listen to for extended periods but the layering is not your typical valve amplifier's style. The treble is a touch on the sharp side of neutral and very extended compared to the VS110 and VT100 Mk.II.The soundstage is very deep and has great width with each track having it's own layer and position without encroaching on any other part of the image. The central image of this amplifier is one of the best I have encountered. It is for precision image freaks. The low bass extension is the best I have ever heard from a 100 watt stereo valve amplifier, period. What you are used to in the way of powerful full bass will be redefined if you have never heard this amplifier before in your system and are used to the common spongy soggy bass tube amplifiers sometimes have. I found there is a hint of dryness in my system with this amplifier in the lower midrange with some recordings that may tend to show up your systems brighter side but this was only evident while testing a digital source. You should be using vinyl anyway.As for punch and slam the VT100 Mk.III has plenty of both on tap for even the most hungry of users. This is no slouch of an amplifier when it comes to it's speed of delivery. I would advise matching this amplifier very carefully with what ever pre-amplifier you choose to use with it. The older Audio Research pre-amplifier's with 6922 tubes tend to complement it's style best in my opinion. Specifically the Audio Research LS15 was great and the SP15 also worked very well.​

Audio Valve har så vidt jeg husker ikke ballanserte inn/utganger og det er must for å matche VT100.
Har selv hatt VT100 MkIII og det var en fantastisk forsterker. Jeg brukte selv BAT preer på denne med meget godt resultat.
BAT VK30SE, BAT31SE, og en BAT VK51SE og spesielt VK30SE og VK51SE var meget bra.
