Solid State Integrated in 1500- 1800 range ?

Magnum Dynalab MD308? New is high $2300 (100 watts/channel)
Perreaux E160i Integrated Amp $1800. (160 watts/channel)

Check out the Sim I-5 used. I've had one for about 6 mo's and while it's only rated at 70w/ch, it sounds much much bigger. I'm driving a pair of Hales Rev 3's and can't decide whether to keep the I-5 or a Llano S-100 (which is a great solid state amp.

The Pliunis 8100 is a great little integrated. It is based off the SA topography. It is a great sounding intergated amp coupled with dunlavy speakers.

I have owned the Simaudio Moon I-5 and Electrocompaniet ECI-3 and liked them both. Just as Woodman mentioned, the I-5 sounds stronger than 70wpc, but so does the ECI-3. However, I don't know how either would fair with planars. The I-5 has the more neutral presentation, and is also more transparent. The ECI-3 is a bit smoother. But I should add that they sound very similar, and this really surprised me. If you get a chance to audition the Electrocomapniet, try to listen to the ECI-4 which is their 120wpc integrated.

The market for integrateds has never been better. There are many many great amps out there. Enjoy!!

Primare A30 integrated could be found discounted/demo etc. for that money. It should work extremly well with 2.3s
