Client Reviews ..


I purchased a Revox A77 MKIII this year and wanted to get it reconditioned. I spoke to a Producer/Sound Engineer/ Studio Owner friend of mine ( I’ve known him 40 yrs) and asked him if he had any ideas about where I should take the A77. He said “I know EXACTLY who you should take it to. This guy is the best in the business.” I contacted Tom and dropped off the machine for a full refurb.

Throughout the process Tom communicated frequently and continually sent high-res. photos of his progress. Upon completion of the work, Tom provided an overall summary of the issues addressed.

I am more than impressed with the timeliness/communication and most importantly the quality of workmanship. I give Tom McCartney my highest recommendation without hesitation.


Hi Tom,

I LOVE the cables! I thought I had good cables but yours blows them out of the water! More depth, more presence, more musical and quieter I think.

I would like to order 4 more pairs, please. 3 can be the same length as the two I have – 30 inches. 1 has to be longer for my amp. Let’s make it 4 feet if possible. 3 1/2 if u think sound will degrade with longer length.

The sound was just more relaxed and enjoyable. You know your stuff! Thanks :-)

Lucio A.
