New Pre/Pro for 2 ch guy? (+How easy to set up RC in top units like Lyngdorf, etc)?

However, been reading that something like a Lyngdorf sounds great, and room correction could make a big diff even in 2 channel.

My experience after hearing Lyngdorf’s technology in his previous TacT technology in a $300,000 stereo system, go for it.  I’m an audio purist and not at all a favor of adding extra equipment or connections, but the benefit or Lyngdorf’s older tech was so profound I wouldn’t live without it.  Without the TacT RC this otherwise excellent system sounded positively broken.  I’d have to think Lyngdorf has advanced his processing since then, and I’d say go for it.  It’s truly revelatory.  FWIW, and best of luck. 

Also thinking maybe doing the Marantz or NAD and getting a Mcintosh C49 or C53 with HT bypass.  Gives me excellent 2 channel sq, but definitely a step down in room correction (and I’m in an untreated slab basement with drywall over 2/3 slab walls, so maybe RC might make a big improvement on everything)

Yes, if you want a wet blanket thrown over your speakers definitely get the McIntsh gear. Good luck with that.

It’s going to be really hard to beat the Krell S1200 because nobody uses discrete analog stages in processors anymore. Everything is op amp based (which can be good, but just doesn’t compare with the discrete Class A analog stages in the Krell). Also, the Krell has a very powerful high resolution sound.

You can go sideways and look for a Bryston SP3. It uses Class A discrete audio circuits both on the analog outputs as well as the fully balanced analog inputs with a "PURE PASS-THROUGH" mode where it does not convert analog to digital. Everything is converted to single-ended internally for volume control. It has probably the strongest bass I have heard out of a processor, but the rest of the sound is not as impactful as the Krell. Probably your best bet for a 2-channel solution. There is no EQ or room correction on this unit.

On everything else, I would look at units that have good linear power supplies. If you really want a Lyngdorf feature set, then look at a McIntosh MX-160/170/180. Those have the Lyngdorf digital/DSP section, but use all McIntosh power supplies and analog stages. Like others have said, if you want room correction, the processor is going to convert all analog input to digital for room correction DSP processing.

Just got bad news from Krell.  Processor is not repairable.  Needs new boards that are no longer in stock.  Ugh.

(soix, why the snooty response to the consideration of a Mc preamp? You were very nice in your original response.  I realize Mcintosh is a polarizing name, but I like what I've heard from them in past, and my mc452 amp is outstanding.  If you like other preamps more, please suggest some as I appreciate all opinions, even if I may not agree :)
