Mod your Beresford 7520

[Spod]

You should be on commission Trailer, just ordered a pair of 49720's for £12.49 shipped and have asked the seller to trim them down for me as he says he will do in the ad

'Scuse the beginner question, but do we have to give the seller any trimming instructions or just ask for the trim? (strange, I have a sudden urge to get a haircut)

[mwahahaha]

I'd wait until we have a solution for the THS4038 case closing problem and then get those - much better than 49720's in my opinion.

I'd wait until we have a solution for the THS4032 case closing problem and then get those - much better than 49720's in my opinion.

Already on order from Tirna, but as its only a few quid per opamp I feel duty-bound to get a 49720 as well and compare them (I'm happy enough with my 4562s now they're run-in but got to check the others!).
So... trimming instructions?

Different mods on my analogue PCB


My WM8716 MOD

And Stan..... Come on. Do they make a clear difference? I assume the Analogue mod is the THS4032 with some decoupling caps across 'something'

Is the DAC mod worthwhile?

Tell us more. Please.

I have no idea if it makes a difference. My test PCB has so many different changes, I have lost track of which one does what to the sound. The picture is just there for others to admire.

Just thought I'd let you guys know that the close case mod seems to have been resolved, the cap is now under the board as opposed to above it.

Cool news.

So Tirna are sending out the revised chip/boards then?



*EDIT*
Walked into that one huh?
