Considering going back to Solid State

I have had and Audio Research REF5se now for a few years and love it. Let me be clear, I love the sound and am not wanting to trade back to SS for anything it does wrong. But I am wanting to simplify and get away from tubes and the heat and concern for hours, etc.

So I am seeking advice in the 10-15K range on solid state pre-amps that would be comparable in performance to what I now have. Considering the Ayre 5 series, SimAudio Moon, McIntosh as a few considerations. Which brings me to you, any experience that you have had making a similar comparison would be helpful.

The rest of the 2 channel side is a Mc402 Amp and Revel speakers, how ever in the next month I plan to either buy the Sopra 2's or the Sonus Olympica Nova III, all cardas wiring in case this helps.

Thank You in advance
