@rwpollock  Robert, thanks for sharing. Great to hear you are 'drinking in' the results. 

The list of excellent amplifier - Nenuphar pairings is growing!!!

@david_ten I am using Raven Audio Silhouette MK2 monoblocks. 6550WC quads 120W each side. 

They did beautifully with not so easy to drive Raidho C3 and another half a dozen speakers. 

Also had a rotation of SS amps but the Ravens were so good I sold them all because I was not listening to them. 



Good to know the Raven works well. Ive got a Reflection MK2 laying around. Im sure its not as good as the Mono's but as long as its in the ballpark.

Many of our posts have focused on amplification. Adding an anecdote that illustrates that everything is important and can contribute to overall performance and sonic results.

I updated and upgraded my Router and Satellite (Mesh Network) yesterday.

The Satellite serves as the beginning / entry point component in the audio system (other than power / power cables).

Wireless in, then wired ethernet to my server.

The update and upgrade was not made for sonic reasons. I am very impressed with the resulting sound quality enhancement.
