Opinions requested


So here is my search for opinions. I'm in the  rabbit hole dilemma. In search for a more audiophile sound and would like to try a tube or Class D amplifier (or combination of both) to replace an aging Adcom 555II amp. The system consists of Lexicon MC12B Pre/pro using zone 2 for 2 channel listening, Adcom 555II amp, Musical Fidelity A3CD CD, Sony PS 4300 TT and B&W 803D2 speakers. I'm looking at many options but am leaning towards a Rogue Pharao Integrated amp which has the best of both worlds (supposedly) Tube pre and class D amp to replace the Adcom. Has anyone had any experience with the Rogue Pharao and the B&W 803 combination? Or other suggestions? Your replies both positive and negative will be appreciated.

I used that same amp with a Sonic Frontiers hybrid preamp and I thought it sounded pretty good.  I upgraded to Bel Canto Ref 500 monoblocks and a CJ classic preamp.  The Adcom/Sonic Frontiers sounded like a cheap a.m. radio by comparison.  I also used a CJ PV 10 and PV 12, they were excellent with these amps as well.  Both the CJ preamps and the Bel Canto amps can be acquired at very good prices used.

 Very good explanation but I believe you have it backwards. I thought that a capacitive load required more current to drive?  
 I'm not 100% on that though as the memory banks are a little foggy and I'm getting old LOL 
Contrary to popular opinion, I’ve heard 803ds sound amazing w high quality push pull tube amplification. Specifically, the Doshi-modified Lectron EL-34 amp. I think it puts out about 50-60 WPC. Maybe model 50.
