Ayon's "Scorpio" tube imtegrated amp vs PrimaLuna Dialogue Premium tube integrated??.

I have considered trying a tube integrated amp. The Prima Luna Prologue Premium has received numerous positive testimonials regarding its sound quality and is considered a bargain at $2399.  Ayon’s new "Scorpian" tube integrated  is more expensive at $4200,  supposedly offers excellent sound quality, but has not gathered many press reviews. .

 Is  anyone familiar with these products??  Are they  reliable over the long haul?? and if so, can either amp  effectively drive any speaker load, including Golden Ear Technology model 7 or the larger model 5.  Or have any problems driving Magneplanar .7 speaker, or any of the Martin Logan speakers.  Thank you

Jim, regarding the possibility of pairing the PrimaLuna integrated amp with some and possibly all of the Golden Ear models which incorporate a powered sub, and possibly with some speakers from other manufacturers which incorporate a powered sub, you’ll want to read this thread in its entirety.

BTW, the issue discussed in that thread would not be relevant to a situation in which the amp is simultaneously driving passive main speakers and a **separate** powered sub or subs.

Jim, to clarify, the Triton Two used by the OP in the thread I linked to has a built-in amplifier just for the purpose of powering its built-in subwoofer drivers.  The rest of the speaker is powered by an external amplifier, in his case a PrimaLuna ProLogue integrated.  The "motorboating" problem that resulted was eventually determined to be caused by instability of the the PL amp when presented with a very high impedance at very low frequencies (the impedance curve for that speaker is shown here).  The problem was eventually resolved, at my suggestion, by putting load resistors of appropriate values on the outputs of the amp.

But yes, I would feel safe in assuming that the fully passive Five and Seven models would not bring out that issue with the PL amp, given their much more normal impedances at low frequencies.
