A quick note on the customer service provided by Tony at Coherent Systems. I've known Tony for several years and have been extremely impressed with the service he's provided over that period. My first contact with Tony was after upgrading my DAC and finding that the resultant tonal balance of my system was too bright. I'd contacted Tony to take advantage of the 14 day trial offer on his cables with the intention of trying to tame the brightness by changing my interconnects. Tony was more than happy to pay a personal visit in an effort to cure the problem and given that he was making a 170 mile round-trip I was more than a little concerned that I would be under pressure to buy whatever products he was bringing along to try and cure my problem. To my surprise there was no 'sales' pressure whatsoever, Tony was clearly very knowledgeable and passionate about his subject and after explaining my problem proceeded to swap cables in and out of my system while I sat and listened to their effect, and what an effect they had! It was difficult to believe I was listening to the same system! Each change of cable built upon the last until finally I had what he called a 'full loom', a digital interconnect between the transport and d/a converter, analogue interconnects from the d/a converter to the amps, bi-wire cables from the amps to the speakers and a power cable on the transport, d/a converter and on each monobloc amp.

At this point the sound-stage of my system was incredible - considerably wider, deeper and taller than with my original cables, also, the replacement cables had reduced the effect of the system brightness by significantly reducing the edginess and harshness in the treble that I hadn't really noticed had been present until now. The last trick Tony did was to plug the transport and d/a converter power leads into one of his Power Master mains conditioners, this moved the system up another notch, with another increase in soundstage width, depth and height, with a furtherer reduction in the edginess and harshness in the treble.

At this point I was completely shocked, it was like all the components in my system had been upgraded to something much more expensive. Over the ensuing months I purchased the various cables piecemeal as funds became available and just recently took delivery of my latest purchase from Tony which were a pair of custom re-engineered monobloc amplifiers based around Bel Canto Tripath digital technology and a customised version of his Power Master III power conditioner. The amps are absolutely stunning, a significant step up from my Krell MDA 300 monoblocs with the bonus of drawing much less current than the Krells allowing them to be used with the customised Power Master III mains conditioner, which has now resulted in the reduction of edginess and harshness in the system to the point where it's virtually non-existent.

Equipment:

  • Wadia 270 Transport.
  • Wadia 27ix D/A Converter.
  • Coherent-Systems re-engineered Bel Canto Monobloc Amplifiers.
  • KEF Reference 4 Speakers.
  • Coherent-Systems 'Connoisseur' Digital, Analogue, Speaker and Power cables.
  • Coherent-Systems 'Power Master III' mains conditioner.
