Marantz PM-55
Good Morning John. I have received the Marantz amplifier and reconnected it to my system. Just wanted to say that the sound quality and response is fantastic ‚Äì even better than it was originally as you suggested it would be. The system in my barn just sounds awesome, and is plenty loud enough even at […]
550k Superchargers – Used as Monoblocks
I contacted John for some help and advice following a poor repair by Musical Fidelity, who had left me with the amplifiers sounding different following a failure. John assured me that he would resolve this and that upgrading them would leave me , hearing how my system should sound’. I am using Thiel 2.4 speakers, […]
Amplifier serviced and upgraded
Great service all round and highly recommended! John serviced and fully upgraded my amp and I got it back a couple of weeks ago. The improvements were clear straight away and as John advised, sound quality has continued to improve with use. It sounds more powerful and clearer with deeper, effortless bass and a much […]
SamS
Over the summer I had John service/upgrade my early 90’s Onix OA21s, which although working fine, I thought should benefit from at least a recap. In addition to the recap John upgraded the speaker terminals, internal speaker cabling and some of the transistors. Right from cold it was very apparent that something special had transpired. […]
Outstanding job, lovely guy
I recently emigrated to the US and needed to get a 120v power supply for my old amp. None were available – MF stopped stocking them a long time ago and I couldn’t find one one ebay or any of the other usual suspects. I found John through an audio forum and contacted him – […]

CD repair and upgrade
Hopefully audiophiles are driven by the desire to get closer to the recorded music when they upgrade equipment. Sometimes these new purchases are significant and the difference is immediately audible. I recall the joy of realising that NAD could do something with amplifiers that Clive Sinclair couldn’t; that a Gyrodec got more from vinyl than […]
CD Repair
The Power Supply Caps in this Player were found to be in poor condition and John replaced them with Mundorfs. Before I bought this player, I read the review by Roy Gregory who gave it the thumbs up. However, his only significant criticism related to a softness in the bass when compared to the very […]
Stage II Upgrade
This upgrade consisted mainly of fitting new Mundorf Power Supply Caps, new Texas Instruments Military Spec. OP Amps and replacement Speaker Conns. For anybody wanting vastly superior contol of the bass and it’s definition, sweeter treble and 3D staging, then this is the one to go for. John warned me the running in period would […]
