Pre and Amp Suggestions

I went thru a multitude of amps last year to get the sound right. Ended up getting back to my roots of Krell amplifiers. I currently using a re-capped Krell KSA-200S, and it has the variable Class A Bias. It doesn’t get hot like my other 2 Krells (KSA-250, KST-100). For the most part, these Krells are a bargain at their used price. I prefer the punch of the Krells over the Pass Labs "smooth" delivery.

Preamps are few and far away a crapshoot as to getting a good "really balanced" unit.

I currently am using a Schiit Freya preamp with (4) 6SN7 Tubes. The preamp allows for 3 levels of listening. Passive, JFET and 6SN7 tubes. Quite good sounding it is, and so flexible with the 3 types of available listening abilities. Tube rolling is easy, with the tubes sticking out for quick changes. Some of the NOS tubes put into the Freya really allow for some great sound.
I use an Audio Alchemy DDP-1 with DAC and preamp in the chain. The Freya is last, just before the amplifier.

The Audio Alchemy DDP-1 is used as the Volume Control with the Schiit Freya used as a way to switch 3 different types of sound into the equation. The Freya tube sound is so good, but some songs it’s nice to go to the Passive, or JFET sound on the Freya preamp and hear it with a little more edge in the sound presentation.

For some it would make sense to just use the Audio Alchemy Preamp. The sound is very, very good with the PS5 Power Supply add-on. Right now you can get both of the Audio Alchemy pieces for $1,500 ($1,000 off) at one of the dealers on the net. The DAC has 8 different filters to adjust to your liking. 4 of them upsample, and 4 of them are NOS.

Putting tubes into the equation with a preamp is something that I needed for Digital Music. I don’t spin Vinyl anymore.

To me... for Digital Playback.... a Solid State amplifier with a Preamp that has some Tubes to soften and add body to the sound. Always get as much power and you can afford.

For reference, I am using a high end pair of Martin Logans, along with a pair of REL S series subs sitting right next to them.

I would love a new Dan D’agostino Progression Stereo amp. In a few years, after the used ones come out for sale. I can dream.

a $10k budget? there is almost too many options of mixing and matching! 
lots of good suggestions so far: Pass labs, Luxman, Atmasphere, ARC, Allnic, etc.

Dont overlook that Allnic that @soix suggested. It is an $11k tubed Pre that is selling in the classifieds for a paltry $3500 or so. Soix might be the seller, but no big deal. If I had the bones, this is what I would buy, or a tubed Atmosphere with a SS amp. 

but I agree that a hybrid system is more called for her b/c of the Lumin server DAC that, although is highly reputed, is still a "digital" device with a vulnerability of sounding too etched on the high end. and b/c an owner of the Revels noted a vulnerability of the tweeter sounding a bit too metallic. 

But you dont want Class A, so you can cross out the Pass Labs options. 

I dont blame your not wanting class A, I use Class D amps currently to keep the heat down and the energy bills down. Consider a quality class D amp with a tube or SS preAmp, like Bel Canto REf600 monoblocks, or any of the designs that are well-reputed on the Audiocircle website forums (D sonic, James Romeyn, etc).  look for the NCore switching designs, they are particularly good. 

Thanks for all the responses and suggestions, lots to ponder here. It’s likely I will go with either a Continuum S2 or Levinson 585 generally because they are more available. I’m still keen on a Pass INT250 or even harder to come by, a Vitus RI-100. I really have no dealers locally who carry any of these so it will be a leap of faith no matter what I get, unless I get ambitious and take a trip to NYC for a vacation/listening tour. 😎

Ok, let us know what you decide, 
but also consider the PrimaLuna hybrid tube/SS amps ...
