Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Saleh84,
Your Gryphon is an excellent amplifier "with the right speaker". Some speakers demand amplifiers with high current delivery with lower output impedance due to low and difficult to drive load characteristics and often steep phase angles. The Nenuphar is the antithesis of this type of speaker. Your LM 845 wouldn’t be a good choice with these current hungry speakers. I much prefer your LM /Nenuphar approach.

I agree, the gryphon diablo is a great amplifier. And i believe the bigger gryphons are some of the best amps - the house sound of gryphon is excellent. However I think it was my choice of speaker being the KEF ref 5s which was the wrong move, they need a softer presentation amplifier probably, and in all honesty as much as i tried to make that combo work, it still did not sound right, certainly not a musical/emotion inducing sound but rather mechanical. It had a district colouration as well. If I had a B&W 802 D3 for example, probably I would have been ok with the diablo and kept things as is.
I could have travelled that route, but hearing the nenuphar's over and over again at my friend's, i couldn't resist anymore, also i was craving to get back to tubes - i started with a tube headphone amplifier, changed to SS only when i moved to speakers camp. The nenuphar was made for tubes, so all was good!

The next step for me is getting a pair of the newly announced cube audio sub 12. I always wanted to experience stereo subwoofers, even with the KEF. I was about to buy a pair of REL S/812, then came to know about the cube offering. I opted for it hoping for a better integration, hope that i made the right choice. Will keep you guys posted how it goes!

May be yes or may be no...
