In Reply to: To what extent can cryo treatment be used in audio equipments? posted by AAA on October 8, 2005 at 03:34:37:
Yes: I have cryo treated whole amplifiers, preamps, D/A convertors as well as transports and laser assemblys, CD's and DVD's. Once you get into this you find there is no way to stop. Wall duplexes, fuses, breakers you name it. Have not done lamps for projectors but would assume longer life if done. Give it a try and see what you think. Haver also treated ribbon foil (4.3 micron) as well as ESL diaphragm mylar. The list just goes on and on. Best regards Moray James.

Whole amps & DAC's?I have to admit, I've wondered about it, but after hearing from Terry Cain (Cain & Cain) about the failure rate of speaker drivers - I dropped that thought.
**Granted, he said those that do survive the process are far superior. But, the cost!***
BTW, Moray - I recently bought a John Wright fully modd'd(+power supply upgrade) Museatex Bitsream and Melior CD-D transport. He recommends your digital cable as the best choice, so I am working up the courage/money to invest in one.
Not kidding! Terry had some troubles with Fostex drivers as they use a urethane adhesive which contracts itself off of the magnet parts if done too quickly. Have talked to Terry about his drivers but not sure what rates his treater is using. Cryo treatment decent/assent of one degree per minute or slower is the trick to success. The caps in your bitstream were probably cryo treated (by me). You should also try one of my power cords with the bitstream as that's what John uses as a reference and the improvement is not small.
When did John rebuild you melior for you? Look forward to hearing back from you. Best regards Moray James.
I actually bought it from someone else whose was upgrading to a mega-buck DAC. But, John remembered doing the unit recently with all the available upgrades - Black Gates caps, Cardas RCA jacks, etc.A month later, I bought the matching Melior CD-D transport, but it is an early version and needs to have the C-lock T jitter reduction circuit upgrade done. Although, it functions flawlessly and sounds fantastic with the Data II Bitstream.

That 6Moons article that someone provided in this thread did a great job of explaining the process in depth and specifically mentioned the potential problem with adhesives and speaker drivers.
I wonder how my entire Bitstream would do with cryo teatment?
Not that I'd risk it because there are so few remaining and it already sounds great. But, it is tempting.
Another potential cryo target are my S&B TX-102 mkIII transformer volume controls, seiden switches, etc.

Funny that you should mention this, I was just looking at those PC's(dac & transport) yesterday and thinking "I bet I could do better". But, all that has to wait until after I get done with room treatments and an equipment rack.
Send me a PM and we can discuss your bit box further. Regards Moray James.
