Atoll PR300 Stereo Preamp, $2500 Made in France! I read a lot of audio magazines. You learn a little here/there in most of them. A common question as you read, is- where are the good stereo preamps? I have always wondered why guys who write for Stereophile only seem to know about preamps that run $30-90k. Seriously?! Atoll has reset the bar…
