Just so you know, system synergy isn't the key. If you take a dull sounding amp and couple it with a bright sounding preamp, the result won't be neutral. Each piece in the system should stand on its own merits! You get far better sound this way and doesn't cost any more.I would pair a Prima Luna tube amp with a Prima Luna tube preamp. System synergy is key.I wish I could, but my rack just doesn't have space for two 8 inch tall devices. And my apartment is very limited so a taller rack won't work either. One of either the preamp or poweramp needs to be like less 6.5 inches tall :(
Need some Tube and Class A SS Suggestions
I recently purchased a pair of Spendor D7s and am just loving these speakers. I have them paired with a musical fidelity KW 500 integrated. The combo is super fast, tight, and dynamic. However, the Spendors can be a bit too revealing in the high frequencies given a harsh or bright recording. This has me headed down the rabbit hole of tube amplification and possibly Class A SS. If the lowest bass is not as tightly defined I'm ok with. It actually may be too tight and defined at the moment. Added warmth in the upper bass would be fine as well. And if I'm going to upgrade then maybe it's time for separates too!
Here are the power amps I'm considering:
I'm curious to hear if any thoughts on what I've picked out already and if there are other units worth looking.
Thanks!
Here are the power amps I'm considering:
- Primaluna EVO 400
- Pass Labs XA25
- Line Magnetic 805IA
- Schiit Aegir Monoblocks - the price is just too good.
- Rogue Audio RP-5 and RP-7
- PS Audio BHK Preamp
I'm curious to hear if any thoughts on what I've picked out already and if there are other units worth looking.
Thanks!

shahram OP for tube amps, given the speaker’s rising impedance in the upper treble region the result of that pairing may be an over-emphasis of the upper treble region, which sounds like the opposite of what you are looking for.What Almarg said here with many tube amps and the Primaluna could well happen, and be a bit forward/etched in the highs. I suggest with D7’s 90db and this kind of impedance and -phase angle, https://www.stereophile.com/images/0415-SD7fig1.jpg go the XA25 or the XA30.8 and if they are too expensive a Class-A Schiit Aegir https://www.schiit.com/products/aegir It will give a good 40watts of power into the bass with this loading and have that Class-A sweetness in the highs even though it’s just 20w Class-A into 8ohms.

Hi @georgehifi Thanks for the suggestion here. The impedence of that stereophile graph really doesn't rise until 10khz. A 10khz tone is VERY high pitched. Not much music above 10Khz so that impedence graph doesn't really bother me. Definitely considering a Primaluna or Rogue Audio preamp with a class A SS power amp. I think if I went class A SS the pass labs XA25 would be my top choice. But part of me really wants to hear what this speaker can do with a Tube power amp...the dilemma continues! |
