Hi, I've been using Temple Audio products for some years now, started with a 'classic' amp which replaced my Cambridge Audio 640 amp (I still use the equivalent cdp). It didn't go as loud using my hard to drive Dynaudio speakers, but the soundstage was much better as was overall quality. Bass was particularly strong even at low volume. I got a 'gold' a few years ago, swapped my speakers with a mate for B&W 603 S3's (easier to drive and more toddler resistant..). Louder volumes much more achievable, regardless of speaker (I'd still recommend higher sensitivity though - my dynaudio's still struggled a bit at 86/4 ohm, but sounded even better at low volume), and the clarity kicked up a notch. I'd so recommend these amps, the quality is frankly startling for the price. I've put this amp in place of an older Naim amp (sorry don't know model) in a friends higher end set up, and apart from outright volume the sound quality difference wasn't really apparent. If you've got a preamp and need more than one input John at Temple Audio will happily build a 'gold' as a power amp for greater flexibility. My next upgrades will hopefully be Tannoy dc6t se's, audiolab 8200 cdq and a pair of Temple Audio monoblocks. I'll be happy with that for many years (probably!)). Thanks to Temple Audio for shattering a few illusions about quality and cost in the hifi world.
