Tube Mono-Block Recommendation

Did you already change the stock volume pot with the Goldpoint stepped attenuator? If you did, I would bypass your preamp and go directly from source to amp. It's an eye opener, or should I say ear opener. A more expensive mod would be to replace the stock output coupling cap with better cap, like the Vcap, which I think is very neutral, very transparent sounding cap. You will need four 0.22 uF caps. These mods will get your amp closer to neutrality without sounding sterile.

its sold my bobs. The pre-amp cost more then the Amps and I find the Purity audio bar far the best pre-amp used compared to even VAC when adding pre-amps into the chain. The purity helps to control the amps correctly. When connecting directly the sound is just so thinner and has less body to it. Bass is less controlled.

I did try the MSB DAD Directly to the Bobs, The bobs sounded dark and slow.

Quicksilver amps are great!!

OK--Iv made up my mind. Im going for the Atma MA2 Monsters. Seems to be the that's fits my requirements.

I must say after emailing VAC, BAT and a few other companies to me Ralph provides best customer service. Responds super fast. This is another reason why I have gone down the atma route. Im not into super coloured Midrange or slow sounding amplifiers. I hope this is the last Amplifiers I buy.
