Nenuphars are very impressive indeed. Was concerned about how my large tube monoblocks would pair with them but they sound fantastic. 

 

Continuing my explorations of tube amplifiers with the Nenuphars, I purchased a David Berning ZH-230 amp from Rick at Hi-Fi One in California. A splendid amp and a good match with the Cubes. A couple of years ago I had used an LTA L10 integrated which is also a ZOTL design. As my mother used to say, it didn't send me anywhere I couldn't get back from.

The Berning amp, however, is like drinking spring water. It has the detail of the Bakoon/Enleum amps but without any sharpness. Definitely recommended for an audition if you get the chance.

Interesting enough, Rick also sent along a passive preamp that he and Steve McCormack had put together some years ago. Surprisingly (to me) it is a very good combination -- that transparency thing.

@eric5kim  They are, aren't they. : )

Which "large tube monoblocks" are you driving your Nenuphar speakers with? Thanks.
