The LS-9100 tube monoblock amps are one of the best buys out there. For under $2,000 now, you get 110W per channel from four 6550 tubes (eight in total). Tube replacement/rolling cost does not get any better or cheaper than this pair. These amps simply sound amazing with any speakers. Bass was plentiful and fast, mid-range was gloriously rich and the highs were sweet and detailed. We had them hooked up to a passive preamp to fully relish the richness of the 6550 tubes. But if you want the full boat on tubes, try pairing it with our Rogue Audio Perseus preamp (listed for sale in a separate listing). The amps are well built pieces with each weighing close to 65lbs. Value for money is off the chart for these amps! This is the second pair from the same owner (we have already sold the first pair) who had two pairs that were bi-amped.
Cosmetically, both amps looks really good. Minor scuff marks here and there common with use but nothing major. We have the original boxes but will double box it for extra safety.
