Mod your Beresford 7520

Hi Dave,
Yes I have put the 2132's in both positions but may experiment a bit with one 2132 and one 4562. I dont possess a pair of headphones so havent tried the headphone output (maybe on my xmas list though....)
The MCL 5/6 mod is not difficult but you need sharp nosed wire cutters to get to the right capacitors nestled amongst other gubbins (thats a technical term). You only need to cut the wire so the bits stay in place and could be soldered back if need be I think. I used toe nail clippers but dont tell Leo or Stan.:)

The Mod takes 5 minutes Dave, take your time and its easy peasy.

Makes a BIG difference to clarity. vocal projection (as Jerry says) and up till getting the 7520 "caiminised", was by far the best upgrade to the sound I'd tried.

It really IS a no brainer.

Thanks Guys (Jerry and Gary),
I'll give it a try maybe, but only after listening to things without snipping any wires and after listening to headphones - 50% of my listening !
Cheers,

5 minutes? what are you doing lol took me about 5 seconds, i mean unless your including unscrewing the case. :P

Shane,
I have a slow screwdriver

Dave,
VERY BIG improvement snipping the wires, very.
Cant recommend it enough, will open up your music - seriously.

Summing up, it sounds more "real"


Go for it.

Lovely soungstaging and a crisp deep bass with the MCL 5/6 mod but the thing I really like is the way voices are projected. A cliche I know but they seem to be in the room with you. I really dont think I want to try the 36K mod.
Leo-please try it again with the 36K removed and see what you think. Its such a cheap upgrade too.

Ok , I promise to take out the R+C and give the OPA2132 another go, I'm currently trying an alternative psu:eyebrows:

Look forward to the results o that one Leo.
The Maplin one I use lets me use one of Frank's(effem) Krystal Kable mains leads.
Does it make a difference?
You bet.

The OPA2132 strikes me as one of those chips that's not perfect, like maybe a little bit lacking in detail, higher frequencies could be just a wee bit brighter, but it's very close with its full frequency response and dynamics, percussive engagements and sounds so nice that it just wants to engage you. If the OPA2132 could speak, it would say "Sit down, stay awhile.":)

I'm actually getting quite discouraged to try another opamp. What with the break in time etc. I'd just like to sit down and enjoy.
