Tube amp for "difficult" speakers,,,

Borrowed a pair of Quicksilver 2 x 60 watt p-pull monoblocs from a friend. Didn't make it. Not surprising. These are good amps and didn't sound so openly "strained" - but clearly, they didn't grab the speakers in the full way that the s-state does. After two days my family said, why dont you put the old one back. I agreed.

Has anyone here tried either the Moscode 401HR [200wpc RMS 8R, 300wpc+ RMS 4R, can be vertically Bi-amped] or the Butler Audio TDB 2250 [250wpc RMS, 8R, 400wps RMS 4R, 800W bridged (mono)] into a low sensitivity circa 83dB loudspeakers with impedance dip to 2R at 20KHz?

Both are hybrid design which whilst giving a valve flavor marry SS in order to provision the power required to drive difficult loads.

Haven't tried them. Can only report back from a Quiksilver monobloc 2 x 60 amp solution, so far. They did not make it, compared to the krell 600, driving the Dynaudio Consequence. Suspect i would need 400 tube watts or more for these speakers.

Have you heard of the new Octave amps from Germany? They are built to drive loads as low as 2ohms.

I own a Butler 2250 and am driving a pair or Ariel 7Bs. The 7Bs are somewhat hard to drive but the Butler seems to have no problem doing so. I listen to my system at 95db to 100db often without issue. I'm not sure you could call the Butler a tube sounding amp in the true since of the word, but I would call it slightly on the warm side. Good luck and keep us posted.
