Best amp for Dynaudio C4

Any time a recommendation for a high powered tube amp to power a pair of speakers is requested on Audiogon, someone will generally mention the CAT amps. Even the stereo version is enormously powerful and features output transformers that alone weigh as much as the average tube amp.

Most high powered tube amps don't sound very good, and virtually none can properly drive speakers featuring low impedances in the bass frequencies. The CAT amps sound superb and can drive speakers that no other production tube amp can drive (not that the C4's are ferociously difficult to drive, but they do like linear power).

I use Duntech Prince speakers incl dynaudio drivers, in a similar d'appolito arrangement as your C4.

My advice will be " politically incorrect" but far from stupid:
Buy a sds470 classdaudio amp ,sales price 590 usd, use it without PA,connecting directly to it a digital volume controlled DAC similar to the Weiss DAC2. The sds sends 2X500W on 4 ohms.

Now, if you dont follow my antipolitically correct advice, you can buy an AudioResearch ref150 ... friendly from france

Pass X series or Krell FPB.

You need some mega tubes to drive the C4s correctly.

I listened to the C2's at RMAF with the T + A electronics. The sound was very nice.

Quality tube amp might be the best for Dynaudio. Octave are good amps but SET Mastersound, class A is even better. 30-50W of pure class A is enough to drive the speakers. I used SS amp, 200W with Dynaudio, now Mastersound is doing the same but better....
