It had been a long while since I have been into Classical and opera,
I put the 1812 overture in the transport and found it lacked scale, while still dynamic it sounded small.
No symphony recording should sound that way. I switched from Triode to Ultra liner and suddenly the preference exploded in both size weight and scale.
Is it that I went from 20 watts per channel to 40 watts or is it something more?
Funny it was not much louder just larger more full bodied.
