Amp and Pre-Amp suggestions needed

I'm in agreement with kijanki4 with respect to tone controls. The better your gear, the less you need them.

For a preamp, I would recommend Don Sach's linestage:

Don builds these by hand and will tweak it to match your amps. The downside is that this means you'll have a 6 - 8 week wait.

I have one and I'd have to spend some serious money to best it.

For an amp, I would suggest looking at a pro amp (e.g., Yamaha, Crown, Crest, Soundcraftsmen, etc.).  

My previous speakers (Martin Logan Spires) loved power so I ran them with a pair of Soundcraftsmen PM860 monoblocks from the 70's. They pushed 900W at 4Ω. Total harmonic distortion was under 0.05%. They were completely silent when no music was playing. If you require big power, pro amps are your best bang for the buck option.

" I'm in agreement with kijanki4 with respect to tone controls. The better your gear, the less you need them."   Thats false.  At 67, my hearing is going and tone controls can be a blessing.

i agree with stereo5 in his statement about tone controls

many many times listening to music i wish i had tone controls handy... if for no other reason than different recordings can have widely varying tonal variations (esp. too hot treble)

Pick up a used Parasound A21+ (the plus is important) amp on audiogon or ebay for under $2500. Plenty of class A power. Neutral sound to let your tube pre shine!
