Not sure why Primaluna is not good enough? I have an EVO 100 integrared running on 89db speakers. It will bring the house down just past half volume. This is with the original EL34s. I just installed JJ KT77s and wow! Better of everything, amazing. They will get louder too. Have you tried KT 77s? Also, the room is likely more of an issue than the electronics would be, my guess. Also, Enjoy!
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?
