Tube Mono-Block Recommendation

Before you spend a lot of money on a new amp, may I suggest a simple mod. Replace the stock volume pot in your Carver amp with Goldpoint stepped attenuator. You will get speed and dynamics that you are looking for and will only cost you $150 for the part and may be $30 for labor by a tech. Changing the input 12AX7 to Psvane will speed things up and make it more neutral. The stock amp is a little sweet sounding, made that way on purpose by Bob. Hope you find what you are looking for.

+1 Dracule1. I found these inexpensive mods to my liking and well worth the effort.

My Hypex nCores do what I think your describing in spades, unfortunately, you sacrifice the second order harmonic distortion characteristic that only tubes can provide.

I'd love to hear what you come up with, please post.

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!!
