Whats playing on your system today?
Gounod's complete works for piano and orchestra (Hyperion).  
Atma-Sphere Class D… Amazing
@lloydc  The AGD TEmpo di Gan is also 100W into 8 ohms, and the Audions are 85W into 8 ohms.  Alongside Ralph's monoblocks, also 100W into 8 ohms, that tells me something about quality over quantity.  
Would There be a Significant Difference
@mike4597 I auditioned at home the Rogue RH-5 (which like the RP-7 has balanced in and out) and the Backert Rhumba.  I found them more similar than different, but ended up preferring the Rhumba by a hair.  Will be interested to hear your experienc... 
12AU7 tubes for a Rouge Audio Sphinx V3 Integrated
I believe the best-sounding new-production 12AU7s are the Psvane ART series (Viva Tubes). If you go NOS, then the world's your oyster.  So far, Amperex are the best, IME.    
The MoFi Mess and TAS rolling over for them
In the October Stereophile Industry Update, it also rolls over on the issue.  Evidently both mags' vested interests are pretty much the same.  
Atma-Sphere Class D… Amazing
This really is rich.  First we have ricevs telling Ralph how to redesign his amps, and now kuribo has a go. Meanwhile, Ralph is model of restraint and superhuman patience.  
Infigo Audio Cables
Pricing??? Are there two lines, Sparkle and Signature??  
Atma-Sphere Class D… Amazing
Unfortunately, "Job" is already taken as an amplifier name. (And that's pronounced with a long o.)  
Recommendations for HiFi Listening Room
Among brands that are more commonly found out there in stores, definitely try to listen to Vandersteen and Sonus Faber.  But just because a brand is stocked by a bunch of stores (B&W, Focal, Paradigm, etc.) don't assume that it's best bang for... 
The new LSA Signature 50 Monitor "Disruptive Product"
When dealing with Underwood, it’s best first to check out very carefully their return/non-return policy on new goods. This is another area where Underwood is very different from Crutchfield, Music Direct, Audio Advisor, etc.  
Please recommend speakers for 45 watt SET amps
Budget? Devore and Audio Note come to mind.  
Recommendations for HiFi Listening Room
You can do a lot better than what the dealer suggested. As per others, the first thing to do is to find two or three brands of speakers that you really like, which may require a bit of travel, but it will be worth it. Once the speakers are set, ... 
I'm surprised that you find the system a little bright.  What kind of room is it in?  Size?  Windows?  Absorbent vs. non-absorbest surfaces? You also don't mention what ICs and SCs you're using.  
Is symphonic music kind of like Phil Spector got hold of chamber music?
Haydn's Esterházy orchestra was 13-24 players in size, what we might often consider a chamber orchestra today.  The bloat--if that's what it was (Wagner and Mahler would disagree)--happened later.  AFAIK, Haydn wrote more symphonies than anyone el... 
Atma-Sphere Class D… Amazing
Classic move: accuse others of what you're doing yourself.
