Hi Mark,

Sorry for the delay in replying, but I got caught up with a few things.

I take your point about the Ultraclock mk2, combined with the matching Ultraclock power supply; however I may still take the plunge and see what happens

How much is that particular modification, and is there any other clock mod between it and the Superclock 4 I currently have in the DAS-R1?

Also, how much would it be to have the LME49720HA for current-to-voltage conversion and AD825 for the analogue filter mods fitted, and could this be carried out when Ian and I visit, presuming we arrived early enough and allowed you sufficient time to do the job?

Marco.
