Mod your Beresford 7520

Did a lot of people just buy one??

I did. I really like the way my AKG K701 sound with the LM4562NA. But the THS4032CD on the output is something to be heard. This DAC has never sounded that good since I purchased it. All in all, this combination works great with my rig. YMMV.

It would be great if Stan or anyone else with more knowledge could advise if there is likely to be any long term damage caused by the Tirna 4032 mod assuming that there is no obvious initial problem.
In my case I just have the 4032 on the left hand socket and a 4562 in the headphone socket. The quality is perfect and I would be reluctant to change unless problems are going to develop.

Just by way of a change from op-amp related issues - What power supply units are you guys using to power your TC-7520?

I ask because I have an idea to use a single 12volt/5volt dual SMPS to power both my DAC and Squeezebox Classic. At the moment I am using a homebrewed 12volt linear for the 7520 and the stock 5volt switcher for the SB3.

My reasons are: 1. Convenience - Just one mains socket. 2. Lower power, more efficient. 3. Better performance than the stock wall-warts.

What have I got to lose? Will the sound quality suffer?

Any comments ...

I'm using the Maplin recommended PSU with an after Market kettle lead. Noticably better than the supplied wall wart

Same here. Maplin PSU at 12v.

You tried at 13.5V?

Any thoughts?

I did with the 7510. Found it too lively and forward. To be honest I haven't tried the 7520 at 13.5v. Have you?

Are these Maplin PSU's linears? - Do they do a 5volt unit at about 2 amps?
