If you run the numbers, the DPHP should have enough power to push your speakers to ear damaging volume cleanly. I used mine with 87dB Dynaudios until I moved on to more efficient speakers. Having options is good though. A solid state amp could be a nice complement to the DPHP, even if it’s more of a lateral move than a clear upgrade. Sorry I don’t have any recommendations though. I went for low power Class A which wouldn’t have enough grunt for your situation.
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?
