SOLD OUT: Adcom GTP-602 Stereo Tuner Preamplifier for $549 with free S&H at JR.com

JR.com has the Adcom GTP-602 Stereo Tuner Preamplifier for $549 with free shipping and handling. The other reputable retailers are all selling this for $899. That’s a savings of $350. Adcom has stopped making stereo preamplifiers, so once the inventory in the pipeline has sold out, the only option (for buying this and other Adcom preamps) will be buying used. I’ve seen some mixed reviews on it (1 guy got a bad unit, 3 others seemed ecstatic about the sound). Consider combining this with the sick deals they’re having on the Adcom GFA-5500 Stereo Power Amplifier for $899 or the Adcom GFA-5400 2-Channel Stereo Power Amplifier for $499.
The Preamp has sold out as of 10:30am on 3/15/10.

REFURB: NAD C 165BEE Stereo Preamplifier (refurbished) for $675 with free S&H

Spearit Sound (via Amazon) has the NAD C 165BEE Stereo Preamplifier (refurbished) for $675 with free shipping and handling. That beats the best price available for a new, sealed-box unit by at least $224. Given the dearth of mid-range stereo preamplifiers currently on the market, this is a good way to go if you want to build your 2-channel system around a power amp (instead of going the receiver or integrated amp route). It comes with a 1-year, parts-and-labor manufacturer’s warranty.
