Schiit Freya S or Freya +?

My Freya S arrived today. I am VERY impressed! It is in my basement workout room and signal is from a Classe CDP.5 cd player via Black Cat IC's into the Freya into a fully SMcAudio modded McCormack DNA.5 amp and then into circa 1977 Large Advents that have been modded (cross-overs, internal wiring) on small stands that tilt the loudspeakers upwards. Speaker cable is Monoprice bulk 12 ga stranded and I am using no connectors-just bare wire. 
The sound right out of the gate was smooth, dynamic, detailed, and spacious, nothing out of place at all. I listen down there while riding a bike on a smart trainer to a program called Zwift so it is a different type of listening-my blood is pumping and I'm sweating and up and down out of the saddle. Not exactly critical listening. But after five years of riding Zwift five to six days a week during winter time, always to music with a multitude of different amps, sources, and loudspeakers, I think I know when there is a marked improvement. This is one impressive $600 preamp. I am a fan. 

Listening tonite, maybe 28 hrs on the unit. I’ve noticed it’s very clear and smooth, with a nice soundstage, but mid bass seems a bit less pronounced than my old Acurus. Not sure that will change much, I doubt it, so I may need to move the speakers closer to the wall.  Though I might loose a bit of depth by doing that. Might give it a few more days of break in. 

In my system around  the 75-100 hr mark the mid-bass down and tonality really opened up and filled in.

Cheers,

Scott

Keep reading the Freya + runs hot to the point that part of the casing cannot be touched. Is this normal ?
I do want to buy one when funds allow

It is normal.  You CAN touch it.  The Freya+ is filled with a lot of components.  Go to the Schiit site and compare the pictures of the Freya+ and Freya S circuit boards.   The Freya S looks almost empty in comparison.  The heat is not from the tubes, but from the 300 volt rectification for the tubes, I think.  Will the heat affect the long term life of the Plus?  For that answer you'll have to ask Schiit.

This had been looking like a Freya S thread,  The Plus with a good pair of gain tubes sounds great, far better then the SS buffer stage alone.  I suppose the latter is comparable to the S (less the SS gain).  Am I correct?
