Is this a sideways move?

Great idea. But you don't need to spend more than $2400 for an extreme game changer, the LSA Voyager GaN 350. You owe it to yourself to get one before you spend 2-3Xs the money for an amp that is not in the same league: SERIOUSLY. Do a search and you will read some amazing reports

hth

Those amps will be different, some very little, some a little more, but not necessarily "better", so the question comes down to the system: driving those small Harbeths, how much improvement am I going to see, even if I choose the "best" among that group (whatever that best one is)? Answer: not a lot.

In other words: the system is well balanced at the moment.  What are you trying to achieve, beyond scratching an itch?

While i enjoy what your speakers do for what they are the Aesthetix Mimas and the Vandersteen Treo CTs pairing is legendary. I promise it will bring on more of what your mind is longing for.

Yeah it seems that my speakers are a big constraint here. Seems I just ought to stand pat. When we move, and there is more space, then I can work on speakers and go from there.

LIke said above, I think I am just scratching an itch.

Very appreciate your responses.

Even in your existing room the TreoCTs Mimas pairing

will allow you to experience how great an amp the Aesthetix is

that you already own..
