Bryston 19" rack handles, consecutive serial #'s pair of 500+ watt monoblocks in MINT condition. Only flaw is 1 micro-scratch on the top of one of the amps, only viewable from directly above amp, otherwise amps are in perfect condition, cosmeticaly and functionally. Still 5 years left on 20 year transferrable warranty from Bryston. Date code of amps is 7/ '07. Serial #'s are 771558/771559. Amps come in original Bryston boxes with owner's manual (might be a copy, I am the 2nd owner), and Bryston Power Amplifier Final Checkout inspections from Bryston (amps output at clipping was 622 and 623 watts, series mode, into 8 Ohms).
The Bryston 7B ST's were reviewed by Larry Greenhill of Stereophile and rated Class A, current 7B SST's are only Class B rated. Excerpts of review are below:
The 7B-ST made a terrific impression on first hearing: open, exciting, transparent, dynamic, effortless. Imaging from the pair of 7B-STs was first-rate, equaled only by the huge dual-mono Krell KSA-250.
The Bryston 7B-ST monoblock power amplifier is an exceptional product. It's very powerful, and joins my reference Krell KSA-250 as an amplifier that can handle any loudspeaker load, play wide dynamic range music effortlessly, and excel in imaging and soundstaging. It can "wake up" reticent dynamic loudspeakers over their entire sonic range; in particular, it brought dry, reticent top ends to life. It equaled the Class A recommended amplifiers at my disposal—the Mark Levinson No.331 and the discontinued Krell KSA-250—in dynamics, transparency, and ability to transmit music's rhythmic pace. The Bryston 7B-ST rates a solid Class A recommendation.
