I had Spectron 1KW for awhile. It lots of detail and great power and bass control, but seemed unnatural sounding. I'm a tube guy, and it didn't come close to my listening preferences, so factor that in to my opinion. But what's more important is that I traded it to a guy who used it bi-amped for his huge woofers. Seemed like a great idea, until it fed so much power through them they literally burned up. The amp was sent to Spectron, who had no explanation for the malfunction. He demanded that they pay for his woofer repair, which didn;t happen. After about 4 weeks, and still not hearing anything from Spectron, he called them again. Now they claimed the amp was damaged in shipping (no mention of this before) beyond repair. He ended up getting a check from UPS. From my experience and my friend's with the 1KW, I would never own any digtal amp.
