Robert,
Yes,
Now I wonder exactly which Bakoon amplifier jtgofish was referring to in his response to Duke on the damping factor thread. It sure seems as though there is variance amongst the Bakoon amplifier models.

There’s the possibility that a number of them could sound excellent with the Nenuphar despite differences in the level of DF. Again one would suspect the higher output impedance Bakoon amplifiers (Lower DF) to be (In theory) the preferred choice.

I can’t comment on the Bakoon 41 with the Nenuphar’s, I only have experienced the Bakoon 13R with the Cubes and like Srajan have found the combination to be very compatible, so there has to be other factors at play here other than DF. I believe Srajan’s preference was the 13R over the 41 but he may not have had the Cubes at that time? The 13R has the latest JET Satri circuit which makes for a very fast response, full bodied and open sound as verified by customer feedback here in the UK.

If anyone in the USA is interested in the Bakoon products, please contact Bakoon directly through their website.

I would agree that although DF is a factor that needs consideration there are additional variables involved that also influence amplifier and Nenuphar compatibility. People are expressing happiness with the Bakoon 13R driving the Nenuphar so something is obviously going right to make this possible.

Speaking of different solid state amplifiers, I was doing some reading on damping factors and came across a link to two Gold Note amplifiers out of Italy, the IS-1000 (integrated) and the PA-1175 (power amp). Both models have a DF option which can be changed on the fly. The high setting has a DF of 250 while the low setting is at 25.

Has anybody listened to one of the Gold Note amps?

@rwpollock Not an answer to your question, and it's been stated earlier in the thread, but just keep in mind that adjustable damping factor and adjustable levels of negative feedback are (always?) synonyms. Might be useful for expanding your amp search if you've been looking for amps with adjustable df...
