This is a 5.1 HT audio system - 2.2 for music. 

For HT this system is very detailed while remaining polite to my neighbors (I live in a condo). It is very easy to hear without getting it loud. It sounds very immersive and realistic. Every time someone knocks on a door in a movie everyone else in the room looks at the door expecting someone to go answer it. 

For music I listen to some classical, lots of retro 70s and 80s that I grew up listening to and even some modern electronic like uplifting trance and house. 

The sound I want: a loud dark midrange that drives the soundstage. The highs and lows are just extensions of that sound up and down the spectrum. I want disciplined bass: punchy, tight and accurate with no vibrations and no reflections and a rapid decay. I also expect the upper and mid-bass to be as loud and powerful and as present as the deep bass. For highs: I love dome tweeters with low crossover points that are balanced and accurate without being loud, hissy nor overdone. Keep the highs subtle. I want to feel like i'm sitting in a bar listening to a band close enough to watch the drummer and feel the drums as much as hear them. 

This system delivers the sound I want. I did have to tweak the sound using the parametric EQ in the S-1200U a little: boost the mids and cut the highs (PKG 630Hz - 3 - +3dB / PKG 3.2kHz - 1.5 - -2dB - output level is auto-adjusted so the boost will not overdrive). The sound stage is immersive. The mids are loud and leaning dark. The highs can still get a little harsh on some songs with the hard-trebles being brittle. The bass is very punchy, very tight and clean. The Cambridge Audio MinX 201 sub - or the Rel T9i either one - is astoundingly clean and punchy for a sub and blends in invisibly with the Veneres. You cannot hear them (but you do). It sounds like all the bass is coming from the Veneres. That's how a sub should be configured to my taste. 

I'm very happy with it. I paid $3k + $500 for the Veneres (brand new). I paid $2.6k here on AudioGon for the Krell S-1200U and Showcase 5 amp. I sent them both to Krell to be sharpened (nothing major needed). The whole system comes in around $7k if you want 1 sub - $8k with all 3. 

I have an XMC-1 as a backup to the S-1200U if it every retires on me. The sound stage is not as large with the XMC-1 as the Krell. It does not sound as clean or immersive but the bass is louder and likely deeper. The highs are more natural on the Krell too (and the price tag was about 6X as much too). 

If I were to upgrade anything at all it just may be the Sonus faber - not that I do not like them - just that out of all this equipment that's the only piece I think I could improve upon within my budget. It would not be easy but there are choices. Nah. It's a keeper - all of it. 

I wish you all the bliss I have found!
