Warm Sounding Speakers

Mirage speakers on SS is not "warm" at all.

Krell electronics will not work well with SF speakers...

So before you go spending thousands on new speakers...why not try a tube processor/buffer to warm it up a bit. I use a Grant Fidelity B-283 MKII, with super-cryoed Electro Harmonix 6SN7GP from cryoset. My Mirage OMD-28s sound warm and beautiful through my SS Marantz. Spend a couple hundred bucks and see if it solves your issue.

Other tweaks that warm up sound. If the tube buffer is an option then choose the 6SN7 based ones like the Grant Fidelity recommended above. Warm 6SN7s are still likely to be truly the best if NOS. The RCA Red Base 5692 tube wj=hile expensive is warm as are other 5692 s which are drop in subs for 6SN7s. Add Ken Rad 6SN7s GTs to the list as well. Although wildly expensive the Brimar Black Glass Brown Bass CV1988 is an incredibly good 6SN7. The cheapest of the lot of warm 6SN7s IMO of course is the Green Label Sylvania GTBs, the various other Sylvanias are good to great but not as warm.
The next trick is to use good Copper IC and Speaker Cables. The warmest in my mind is the Cardas Golden Refs, expensive you'll prolly have to buy used. Look for Cardas anythings with Golden in the name, I am not joking. Also Jena Labs but even the entry level stuff is expensive.
You could just buy an older CJ pre amp for less and get warm sound that way.
Rembember tube power amps are your best bet in the end, I just don't advocate ARC for warmth they are clean crisp precise and defined (it's in their slogan.)
