Stick with tubes. It’s always a challenge in a small room because you’re forced to put your gear exactly where it shouldn’t be placed. I agree with the consensus suggestions that you should address your room and maximize its possibilities. Is it possible to set up your room to where your gear is on the long wall, and not the short wall? I have a similar room, and that’s what I did. I’ve 9 feet between the edge of speakers, and have 4’ on the right wall, and 7’ on the left wall. My sound stage is much better and wider. Anyway, explore different options for your room.
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?
