PrimaLuna Prologue Premium Power Amplifier. Black. 1 month old. No defects. Wonderful EL34 power tubes and 12AU7 input/driver tubes. The sound is powerful and extended in the bass and treble. The very attractive sound of the EL34 tube is present, too.
Please look closely at the images. Compare this very late version, unmodified unit for sale against the brand new $2,699 list, $500 more expensive EVO 200 amp. They are exactly alike, except for the printing on the front panel. Get the latest configuration and save! The white capacitors in this latest version amp are the same as used in the top-of-the-line Dialogue Premium and EVO 300/400 amplifiers.
Features include auto bias, bad tube indicators (VERY valuable for troubleshooting), and stereo/mono switch.
A tube power amplifier is only as good as its output transformers, measured in bandwidth. Compare the ProLogue Premium to other amps (higher number is better):
ProLogue Premium: 65k Hz
Conrad Johnson Premier 62 SE: 30k Hz
Audio Research Reference 75 SE: 40k Hz
VAC Phi 170: 40k Hz
McIntosh MC2152 70th Anniversary: 30k Hz
Lamm ML2.2: 30k Hz
Due to different measurement tolerances, some of these numbers were interpolated. As you can see, the PrimaLuna amplifier has the best output transformers - by a large margin! This means the best upper frequency response for the best clarity and transparency!
"PrimaLuna's output transformers are of excellent quality." -John Atkinson, Stereophile Magazine
Also Included - a matched pair of Shuguang 12AU7-T tubes. The "T" is their top grade "Nature Sound" tubes, which are supposed to be better than the less expensive "Z" Treasure grade. The 12AU7-T is reportedly one of the best, current production 12AU7. Please deduct $50 from your offer if you do not want these tubes.
Money orders also welcome. Asking price includes FedEx Ground insured shipping in the US. International shipping at my cost. PayPal is accepted from Verified accounts and adds the usual 3% or send "Friends & Family" and save the fee. Please ask any questions and I will be happy to work with you..
