How much heat can it possibly make? Is it appreciable enough to even worry about or to make much of a difference in room temp? I own a class A Amp that gets quite hot, but I mean I'm not sitting on top of it or near it. I use it year round...no idea why some make this an actual issue..it isn't.
Upgrading from Primaluna
Recently went down the front end upgrade path and am running a nice table and phono now. I'm curious as to what the weaker link in my system is between my Primaluna Dialogue Premium Preamp and my Dialogue Premium Hp Power Amp. I'm considering swapping out the amp to a Ps Audio BHK250 for the summer to avoid heat, but am curious if I would be better off dealing with the heat and moving up to say an Allnic L-7000/Arc Ref 3 for the Pre. I'm happy with tubes on the front end, but curious if I'm running out of gas with 88DB efficient speakers and a single chassis tube amp. Which amp would you upgrade first and what benefits would you expect?
