+1 for the PS Audio S300 combined with a tube pre. I ran an S300 with a Rogue RP-1 that was upgraded to Mullards. I just recently sold the S300 for a QUAD class A/B that runs a little bit warmer than the s300. Im not sure it sounds that much better than the S300 especially at x2 MSRP. If I ever switch back to class D which I may do I will surely consider the S700 mono blocks. You can pick up an S300 for about ~$1K and a Rogue RP-1 for about the same. , RP-1 runs mildly warm. I also like the Rogue Hybrid integrated suggestions.
note: Rp-1 over on usaudiomart for $1.1K and a S300 for $950. Killer combo for ~$2K
