If anybody’s interested, just put up some more photos on my virtual system page with better views of the speaker cabinet finish.

Continue to be impressed with the sound of the Decware - just amazing clarity. I’m thinking... Nenuphar with direct wire to driver (no crossover) plus simple signal path of the Decware (one V-cap capacitor and two resistors) = absolute signal purity.

Also, Vinnie Rossi L2iSE in preamp only mode - directly heated triodes (DHT) run in a dual-mono, class-A with zero feedback, Belleson super regulators for ultra-quiet linear voltage regulation of the triodes, no coupling transformers, internal DAC with (inches) short signal path to preamp stage, discrete, 64-step resistor ladder volume control using Pickering England silent signal relays.

Minimalist approach brings out the absolute best in the Nens.






"great looking stereo! love the finish"

 Agree! Dark, rich and very elegant and matches well with the color of the cone. Really nice high gloss finish.

@david_ten.  Thanks for that specific feedback.  I like that you play stuff that's hits harder than my examples.  I think that's the right word for the sort of music I wanted to make sure the Nenuphars could handle.  Thank you for confirming!
Survey: I thought it would be interesting to know what speaker cables you are liking with the Nenuphar’s? Thanks in advance.

Currently I’m using towards top of the range Hi-Diamond.
