Amp/Preamp Asylum: REVIEW: PrimaLuna ProLogue Seven Amplifier (Tube) by charlie@cunninghamparris.com

Model:	ProLogue Seven
Category:	Amplifier (Tube)
Suggested Retail Price:	$3,149
Description:	Monobloc PAIR of power amps equipped with Adaptive AutoBiasâ„¢ exclusive to PrimaLuna, means no user adjustments and tubes are kept in their â€œsweet spotâ€ for lowest distortion in real time. Like all PrimaLuna amps will use most power tubes from 6L6GC, KT66, EL-34, 7581A, 6550, KT88, KT90, and others. Soft-start circuit extends component and tube life by powering up the amp gently every time you turn it on. Tube plate fuse protects the amplifier output stage. Custom designed output transformers encapsulated for low hum, wide bandwidth for great bass and extended highs. Premium parts. Fully vented, chassis-mounted ceramic tube sockets with KT88 power tubes, Frech-made Solen Capacitors, and Philips fast-recovery diodes. WBT style speaker terminals and gold plated input jacks. The finest point to point wiring, with workmanship equal to or better than any product you can buy at any price. Chassis made of finely finished heavy gauge steel, and five step automotive quality finish. Each coat hand rubbed and polished. Quick-release tube cage included no charge. Toroidal power transformer for low hum and an amp that is dead quiet.

I purchased these amps from "Upscale Audio" a little over a month ago and over that time they have warmed up to be a wonderful addition to my music system! I have listened to quite a few power amps and these are the best. I listen to a lot of Opera and femal vocals, so the warmth realy comes through as well as the highs and a good base when called for. I use a "Sonic frontiers upgraded Line 1 preamp" and Alone Lotus speakers to round out a wonderful combonation!
These amps have made the biggest improvement that my ears have experienced in for ever! I have been listening to tubes since I built my first "Dyna 70" so long ago I dont want to talk about it.
Thanks so much to who ever produced such great sound quality (not to mention the build! and finish!).

Product Weakness:	none found
Product Strengths:	Lots of subtle power and big sound stage
