Mod your Beresford 7520

I would agree.
I tried most of the usual suspects and settled on the AD826. Everything sounds more musical and natural.

Me too.
Tried loads of different ones to the point of nausea..
826 defo the best for me.

LM4562's dont sound as much like a good record player as the 826's!

I have been trying to borrow/buy two pieces of AD826 in order to try them out, but no luck so far. Anyone knows where I can find a pair of them?

If you do a search in Google or the forum for Tirna Electronics you should be able to get the THS4032 from there. Many people on AoS uses their service for mods etc.

Thank Stanley,
I know, I read it on previous pages, they seem to be the very helpful and knowledgeable.
BUT, they do NOT sell it any more!!!!

Copy/Paste from them:
"We no longer sell these, due to a fault that we are still investigating."
"the only reason we stopped selling them on adaptors is that about 50% of them were instable and oscillated at MHz. This is because they are very high bandwidth and are trying to drive too much parasitic capacitance across the leads to the headphones or power amplifier in Audio DAC applications. there is a standard "fix2 for that but we have not had time to investigate it as yet so we are not selling them until we do sort the problem. It is quite possible that you would encounter the same problem with the one in the link."
"It is most likely fixable, but we haven't tried yet. We will put the news up on our website (www.tirnaelectronics.co.uk) when we have a fix for it. So keep checking our website. Apart from that, I cannot give a more firm answer of when we will have it ready for sale again."

I wonder where I can get them with adapters, and of course without the fault?
Anybody else had similar fault with THS4032?


Also, it seems that AD826 is maybe better option than LM4562NA? (for some ears of course)

Good luck with your search for the THS4032. AD826? Heard of them, but never tried them. Everyone has their own preference, so buy up a set of all the opamps recommended on the forum and see which ones you like.

Also seen the AD826 on Farnell for the same price, in case they are easier to deal with: http://uk.farnell.com/analog-devices...826/dp/1438583

In my experience and opinion all those electrical merchants including Farnel, RS, digikey etc.. are cumbersome to deal with, due to their higher postage prices and some strange rules.
Maybe I used to eBay too much?
