Definitely not, in my experience. I had mine rebuilt by Threshold for over $1,100 US plus a couple of hundred for transport, 3 years ago, only to have a channel not only fail, but output speaker-destroying DC a year later. It took months to find an audio technologist (it is so difficult to work on that no technician would take on the work). After more more months and nearly $1k Canadian (and he gave me a hefty discount), it worked for a year or so, only to have the other channel go. Replacing blown fuses on a good local tech's bench resulted in 35 volts of DC output and acrid smoke from a burning fireproof transistor.
I'll never buy another Threshold product or similar esoteric-fringe "audiophile" product.
