Hey Dave.

How did those op amps work out?

Now that you've changed your name, and being a fat guy (me, not you), it is my fervant hope that you'll change that grotesque dancing chubster!

Peace!
Doug

Hi again Doug,
To be honest I haven't yet swapped anything - still getting a feel for the un-mod'd version and I have also, at different times, installed new speaker cables and new phono and co-ax leads into and out of the 7520 - still looking for a better optical lead and possibly USB lead for same application. Once I've settled on these I'll try the op-amp swapping. I took the lid off yesterday and gently lifted one op-amp, without removing it completely - seems easy enough !
I have also been keeping a close eye on the 7520 Mod posts on here and trying to see if any concensus of opinion accrues but at the end of the day the swap I will go for is the one that I prefer. All the same, any concensus that might accrue will probably be my starting point.
Cheers,

still looking for a better optical lead

I do a set of those that are far superior than some of the ones out there that you pay five times or more for. If you can find better than mine for less than £50 I'll even offer you a refund on your return postage.

Good Morning Stan,
Just as an 'aide memoire' I quote below our recent exchange of PMs on this subject (you must get lots every day - difficult to recall any particular one.)

Thanks for your help,
Dave.

Hi Dave, they are available from:

The reason that I didn't follow through immediately with an order was that I couldn't see any reference on your site to any different lengths or indeed any length at all, and then other things tended to push it to the back of my mind. Without inviting you to knock the competition I also contacted Mark Grant with a similar question and he has also apparently forgotten about me, (I'm beginning to get a complex about this ), as he also never responded to my follow up query, but how does your TRC-222 compare with Mark's?
I would be very happy to order a TRC-222 from you if: -
1) you can advise me about the length(s) available, with reasons/logic if only one length is offered (I'm keen to learn),
2) you can offer me the usual(?) AoS discount, and
3) my name goes on the list of loaners for the new Caiman PSU upgrade
(hope you are still smiling )
Being serious for a moment, the above 3 'conditions' are expressed in order of importance .
Look forward to hearing from you in due course.
PS
In view of your lack of comment am I to take it that you don't offer a 'Stan' grade USB lead? If so, are you able to advise where I can get a 'quality' one from? Afterall, the hub of this mini-system is the 7520 and it makes sense to couple it with leads known to enable it to give of it's best.
Cheers,

Hi Dave, the TRC-222 is not an optical lead.
However, that aside, the other details of the lead are:
1. It comes in 1 meter length.
2. It is superior in technical construction, weight (amount of conducting material), and bandwidth to the £150 Siltech London, which is the only other high-end lead in the world that that I know of that uses bare PCOFC as the conducting material.
3. I sell them at cost plus whatever the taxman fleeces me for just selling them. My cables are not bread winners for me, so discounts are therefore not offered. I merely offer them in order to make it easier for customers who live in no-man's land to do a one-stop shopping for a high quality lead.

I heard that Mark does a range of very classy stuff at competitive prices. My suggestion would be for you to give him a shout again. He is reckoned to be a very busy man, so I am sure he has not overlooked you intentionally.

I can fully vouch for the Toslink XQ cable.

I took a peek at the core under a jewellers monocle, lots of invididual strands of optical fibre.
My £4-for-10-metres toslink cable has a solid plastic core, I dread to think what it was doing to the signal

It should be noted that 10mhz is the recommended optical bandwidth for maximum performance in the Toslink / SPDIF red book. These cables meet that standard (and very probably exceed it).

That standard is for 2 channel, 16 bit, 44.1KHz equipment of yesteryear. My cable is for 24 bit/192KHz and will handle 7.1. Realistically I should be charging £50 for that lead if I compare it to what else is on the market.

Hey everyone,
So I did the first mod last night, substituting the opamp for the LM4562NA and removing C5/6. I am using a toslink that is pretty long ~25 feet or so.
Before I did the mod, there was always a little popping sound when the first sounds came on, but now it is there every time the song changes...any ideas?
In any case, I may try moving the computer closer and see if that has any effect.
regards,
byron
