Mod your Beresford 7520

[maxrob200]

Koetsu Gold and Signature MC were smooth as silk especially in the mid-range to recall from memory. If the Wolfson DAC is that good compared to the current 7520 DAC it is really something special
I want one!

[lovejoy]

With the WM8716 it reminds me of the Koetsu Gold I used to own.

Dammit Stan, now you've got me wanting one

I need to find someone brave enough to perform the mod. There's no way I'd attempt that one.

I've just ordered a couple of AD826's from RS.

I'll have enough to open a second hand op-amp shop shortly.

I hope you like the AD826 as much as I do. I'll be interested to hear your comparison to the metal can 4562 (or is it the 49720 you have?).

BTW - Did you sort out the "popping" noise on the optical in?

It's the 49720 can I have in at the moment.

I'll get the op-amps tomorrow and I'll have another look (listen?) at the optical again.

Just received the Wolfson WM8716 DAC chip in readiness for the upgrade. I am a little pushed for time at the moment and I don't want to rush it so I'll keep you informed of the swap when I get round to it.

Also in the mailing I ordered a AD826 op-amp which I have just installed in the headphone socket.

I'll leave it burning in but first impressions are very good - I have been looking for the word to describe the sound - And that word is "Refined" with a capital R!
This chip is without doubt the best I have tried to date IMHO - really makes the K701's sing - Not a hint of bad manners like the 4032, it just reproduces music - And how.

I advise you try one (or two). I can hardly wait to hear how this is going to sound with the Wolfson DAC - Ooooh I fell quite excited - Guick nurse, the screens....

Hello,
What is the original dac chip used in the TC-7520 ?
I tried to search the forum and homehifi.co.uk website, but couldn't find that information ...
Thanks a lot

Hi, standard DAC chip is a Burr-Brown PCM1716.

I have wharfedale 9.2 speakers and akg k701 headphones, just wondering whether putting in the AD826 will make a substantial difference to the headphone output from the 7520?
I am using it as a standalone headphone amp.
Thanks

As with all these things, it's always subjective. But personally, I think the AD826 is as good as it gets, and I am using K701's. I have an LM4562NA in the line-out socket which I also think is a good choice.

I suggest you look through the thread - There are several op-amps and combinations you could try, and most are reasonably priced. So have a go at op-amp rolling, there is nothing to lose and plenty to gain

Let us know how you get on.
