This would be great Stan, I can see this being a busy one
Come on guys, surely somebody here wants to get the ball rolling
Well, I would have thought that you're easily the most qualified person on here mate (along with Stan obviously), so give us your thoughts.

I've been intrigued by the Mod 21 since finding out about it, but I'm very loathe to lose my DAC for a (short) while.
Any chance of some details ?

Starting with the simple upgrades that do not require opening the DAC:
One of the first things people ask me is what they can do to upgrade the power supply. The one I ship with the TC-7510 is a regulated version that works on anything between 90V to 260V. However, a regulated linear power supply of at least 300mA and not more than 15V off load gives better bass handling ability and a fuller sound.
The Maplin unit at POWER SUPPLY
is also a good upgrade, and frequently mentioned. It is also on offer right now.
Next question I get asked is about USB. Again, Maplin does a unit that fits between a USB port and the TOSLINK input of the TC-7510. USB ADAPTER.
Just do it and see if he notices.

Once this thread starts to get busy, I'd imagine it will and things have been tested by others and approved would you like the main mods, tips etc selected and placed into a sticky Stan? it may make things easier to find
I have put a pdf file HERE with some brief details of the mod.
However, I received an email from someone who has gone a bit further. After he removed the caps, he also removed the JRC4558 opamp sandwiched between them and fitted a LM4562MA instead. Then he did the caps upgrade using some expensive ones sourced from eBay.
Someone else left out the caps close to the RCA output socket (the originals are 100uF if I remember correctly) and soldered wired links from the + side of the caps, directly to the centre pins of the fixed RCA output. That means that the variable output won't work any more, and neither the headphone amp. However, the sound quality makes a respectable leap. The DC blocking is now done by the caps at the AUX input of whatever the DAC is connected to.
Hmm, so for the Mod21 are you increasing bandwidth of the op-amp?
