I’ve now put some 50hrs on my newly upgraded Cambridge Audio power amp. When I first got it home, after the upgrade, I was not sure what exactly to expect but the difference was immediately obvious. Within 20 minutes I detected improvements across the frequency range. Bass and midrange were most noticeably improved and my Monitor Audio Silver 8 speakers for the first time sounded musical. Now, as the burn-in time has elapsed I’ve discovered an expanded sound stage too. This amp has total grip on the 4 ohm Monitors. I had intended to upgrade the speakers to some PMC 25 23s but JS Audios upgrade has been so overtly good that I’ll keep my set up as it is. For a relatively modest outlay my hifi has been given a real shot in the arm. I highly recommend JS Audios incredible electronic magic.
