Hmm, interesting. It seems a bit dodgy to me that they're offering the same mods for 7510 and 7520 when they have different designs.

I'd be interested to hear what Stan has to say about those mods.

I guess I should increase my prices for mods...

Now look what you have gone and done!
Seems a lot of money when you think the op-amp and adaptor is only about £12.
Leo's view on these mods would be welcome as well.

At least they tell you what you get for your money and offer options ranging in price, obviously considered a bit pricey for the diy bodgers amongst us but for those not capable of using a soldering iron should offer some performance boost

I've actually fitted some of their Spower regs in somebodys cdp a while ago so know how those ones perform, their pretty good although not cheap

BTW I notice in the more expensive mods apart from the upgraded regs the amount of Rubycon ZA caps adds up, I'd imagine these are going to replace a lot of the tants Stan chose to use around the dac, receiver etc.
These type of caps do have an effect on the sound and will effect tone IMHO, they will sound noticeably different to the tants

Well I think I will stick with the Cayman!

The tantalums are only handling digital signals, where they perform a crucial function in keeping the clock timing accurate. Swapping them over for those Rubycons is going to cause some negative effects. I tried that already in the TC-7510 MKII and had to abandon the idea in the MKIII. The sound was very incoherent in complex musical arrangements.

What would be the general concensus on the power mods?

So this company has simply replaced medium priced components with higher quality ones in the belief than an improvement will be forthcoming.
I wouldn't touch them with a 10 foot bargepole.
It must get you very annoyed Stan after all the time and effort you have spent on development.

If you really want to try out some high quality regulators, then you need to look at the Murata 7812SR and the Murata 7805SR. You'll need a 15V regulated DC external supply to go with that as well however.
