Item Repaired/upgraded: X-A1 & X-A50's 

Having had an X-A50 Bi Wired with a pair of X-A50’s for many years I had considered an upgrade. Spoke with John and liked his upgrade recommendations. Was a little nervous sending off my precious kit but within a few weeks it was returned.

If the increase in weight was a measure of quality I was not going to be disappointed.
From the off there was a distinct improvement in all round quality and as the weeks have gone by it has only got better. A fantastic upgrade and worth every penny.

Just a few words to say how pleased I am with johns service on upgrading a faulty M3 amplifier. Sounding more musical and refined, would definitely recommend his service and upgrade.

Item Repaired/upgraded: Repair and Upgrade 

It's been a month or so since picking up my upgraded A308 amp and cd from John.
Having given them a bit of time to settle in I thought I was time to make my review.
What can i say but 'just wonderfull', the music is now clean and clear, soundstage is massive, bass is powerfull and controled with much more punch.
Also having the phono section of the A308 amp fully upgraded has made a huge improvement to the performance of my Roksan Xerxes 20 turntable. Saved a fortune on buying an outboard phono stage.
Thanks John.
Very pleased..

Superb upgrade.
I think it is nothing better than listening to live music.

Item Repaired/upgraded: Uprgade 

Not satisfied with my McIntosh 501 power amps (£8000) and discovering Johns' website I purchased this amp on ebay.
John upgraded the unit for me and the results are staggering.
If anyone is thinking of getting new equipment then go to John for advice/work and not only will you get a superior piece of kit but save yourself a packet at the same time!
