Thanks, Charles. I suspect that I’ll eventually sell the VAC, but I won’t decide until sometime after I receive it back. The XA25 is definitely a keeper, though, for the long term. It comes amazingly close to the VAC with respect to dimensionality, imaging, liquidity, and other traditional fortes of high quality tube amps. It’s a bit less rich sounding than the VAC, but I interpret that as an increase in accuracy, which is fine as far as I am concerned.
There are also some non-sonic factors favoring the XA25, including the likelihood of greater reliability in the years ahead considering the age of the VAC; the fact that even though both amps operate in class A the XA25 puts only 240 watts of heat into the room compared to what I believe is upwards of 700 watts for the VAC; and the cost that would be involved in re-tubing eight 300Bs if and when that were to become necessary.
This is the first time I’ve had a high quality solid state amp in my system in about 25 years, and I believe I’ve picked the right time and the right model with which to do so again. Thanks in part to Terry's review.
Best regards,
