Mod your Beresford 7520

[Gazjam]

Sorry Gaz, our posts crossed. Not sure what the avatar is, I think I picked it up from the cover of some graphics software. I just liked the way it looks, great upper body there, innit?

I asked cos I do that stuff meself

Not bad, nothing compared to mine though.

at the time I was still doing a Saturday job at Sevenoaks so could audition plenty.

Where can I get signed up for one of those? lol

Yeah, difficult stuff picking up the amp. Mind you, it's about as difficult picking up the right speakers for a certain amp. To your taste, that is.

Not bad, nothing compared to mine though

Yours as in your avatar, or your graphic work? Why don't you make me a nice one, I'll be proud to use it. No shit.

Gazjam did the original artwork for the TC-7510 MK6 and TC-7520 front panel out of interest. That's one of the reason why I laugh when people claimed I rebranded the DAC from someone else.

Great stuff. Seriously. And I was not joking about being proud of using his graphic work, I hope I was not creating wrong ideas here.

I have been commissioning work from Gazza for some time now, and he only let me down once.

[Gazjam]

Gawd, thanks Stan!

Alexxus, as proud of my work as I am, I was meaning my super great upper body!

Raised a smile here too.......

especially when folks from one forum were quoting from another (all wrong info too)

Well, I spent practically all day yesterday trying out op-amp combinations and thought I'd reached a happy conclusion. I was using my old DVD player as a source at the time and after hours of listening was absolutely blown away by the sound using the THS4032 in the line out socket and the new 2132 in the headphone socket, also using 100nf/12KOhm combinations in the MLC 5/6 sockets. No matter what I played, it was thoroughly enjoyable and did not set a foot wrong. Then later in the evening I got my Macbook Pro back from work - my main source for digital audio and assuming the improvements would continue, I simply hooked it up and started playing tunes..

But what's this? It's flat, boring and lifeless. The treble is a mess, the bass has sunk way down in the mix. It's just completely musically uninteresting. Oh!

So it would seem that the 4032/2132 combination is the best for the DVD player, but in order to get the Mac to sound that good the 2132 returns to the lineout socket and the 4562 to the headphone socket - keeping the 100nf/12K pairs in place which seems to help the wayward bass somewhat in this combination.

I'm speechless at how much difference the source makes, and that's using the same interconnect too!

I think I am starting to have second thoughts about the 2132. Its bass, although well controlled is too heavy. I noticed this tonight listening to vocals. Its like you have a loudness control on (remember them?). Its a shame really because it ticks so many boxes. Probably in a bigger room or with standmounts it would be fine but its just a bit too much for me.
Tried the 5532 in the HPA Gaz but didnt notice much difference.
So which op-amp to try next?

Well, I tried listening to the AD826 again today, but after going through 4-5 different genres of music, most of 'em well recorded (SHM or MSFL versions), I just gave up and chucked it away, popped the old 4032 in instead. Damn, it sounds good , I love my B-DAC.

For some reason, dunno if its opamp interaction or I just hated the way line out sounded with AD826, but last night it seemed to me the HPA sounded best (with the AD826 in line out and the 4562 in the headphones out, just to remind everybody). Whatever it was, since I use it as source just as much as an HPA, I'll live perfectly happy with the way it is now, with the 4032 on line out.

I was expecting more from the AD826, after all it was the most expensive opamp of the lot, but it was the most disappointing. For a while I'll just enjoy the music, when I get restless again I'll start on the caps & resistors game
