[SteveW]

Oh...and where do you get them from?

Hi Steve
For a good explanation read post 442 of Mod your beresford 7520 under The Drawing Board. There are a lot of useful photos and bits of info earlier in the thread.
We got our op-amps from Tirna Electronics and ordered through Ebay although I dont see their listing at the moment. Briefly the best op-amp found to date imho is the THS4032 but this does not have long 'legs' to fit in the sockets of the 7520. An adapter board is required and this raises the op-amp requiring a capacitor to be fitted. Fear not because Tirna fit the capacitor to am adapter so its simple a case of repacing one with the other. Cost is only about £10 for one. You only need to replace one of two if you dont use headphones.
It all sounds more complicated than it really is.

They are both great dacs.

Given that you dont need USB I'd go for the 7510 - buy some music with the difference in cost!

Dont feel your missing out getting the 7510 over the 7520, both are fantastic sounding - just aimed at different markets.
The 7520 DOES sound better - through both headphone AMD line output - its just whether given your system at the moment you would actually benefit from it.

I think the 7520 would be overkill in your system. I take it your playing Lossless files from your PC and not just MP3?
That'll make a bigger difference in your system than the 7520 vs 7510 I feel.

Also, something else to think about...
If you use USB rather than spdif from your PC, it will bypass the computer soundcard and the windows audio drivers, which can affect sound too.
Google a thing called ASIO4ALL, if you want to use spdif you will want your signal running into the dac to be "bit-perfect", which this software can achieve.



Hope this helps.

Sir,

Have you posted detailed review/comparison between 7510 & 7520?
If yes then can you provide me the link?

Thanks.

I went straight for the 7520 as the price difference is not great, plus after reading the posts on this forum about the easy upgrades of the op-amps in the 7520 felt it was a no-brainer decision. I have just upgraded the op-amps in my just run-in 7520 with LM4562NA and the sonic difference even from cold is pretty obvious. Given a running in period, I expect the entire sonic presentation to get richer and more spacious in soundstage. Plenty of PRaT and musicality

My main interest will be listenting music off either DVDp or WD MP.
So I thought of 7510.When I read reviews from senior members of 7520 ,I got confused.

I just want to know will 7520 sound better than 7510 with the given sources?
Currently I own Tannoy F1 .

Thanks.

Since the F1 is a ported cabinet I would suggest the TC-7520 with the LM4562NA opamps. That will give you bit more grip and definition in the bass. The extra cost is about £70 compared to going the TC-7510 route, which is less endowed in the bass department.

stratovious,

the 7520 sounds better than the 7510, even before any Op Amps are upgraded, external Power Supplies are added etc.
Dont get me wrong, the 7510 sounds great too.
But the 7520 is a different Dac, with better internals hence better sound.

It has a LOT of Bonuses over the 7510 also;

USB Connectivity

First Class Headphone Amp
(and I mean FIRST class)

Easily upgradable with better Op Amps.
(This can make a dramatic upgrade sound wise)
