Anyone finished burning in their TC-7520 yet?

**mrwarby** · 19-03-2009, 00:59

I don't wish to create the illusion that one needs to dig even deeper in his or her pocket in order to get the TC-7520 to sound fantastic.

That's good to hear.
I would hope to keep it for at least 6 months before trying anything as I think it already sounds more than enough for me, maybe future updates would be to the USB. I would be quite happy to have a look though as I was using a dual trace picoscope today to fix something for work.

Anyhow, my Squeezebox is in the post, my PD-91 CD player is raring to go, my daughter has her Eee pc set up and I'm working on the mrs to buy me some headphones for my birthday and my question is, is it Ok to buy one now or wait a few months for things to settle down?

Quite a big improvement. More detail, bigger soundstage and smoother all round.

I replaced both yes.

. What's happening in the next few months that needs settling down?

Sorry to labour a point but can you confirm the replacement op-amps are not soldered-just clip out and clip in?
Are these the right ones-LM4562NA dual opamps, 8 pin DIL (MDIP) ?
Thanks

Yes. And they're the ones I used.

Thank Trailer. I have bought a pair off ebay for £8.99 including p&p. At that price I wont be upset if they dont make any difference.

No problem. I'm just listening to mine again this morning and it really is an improvement. Smoother, more detail, better controlled bass, bigger soundstage.

The ebay seller has just send an email thanking me for the purchase and put that the LME49720HA is even better-what do you think?

I'm not sure if they would fit* without a bit of bending.

*height wise

I got the best performance from the THS4032, but it is a surface mount chip. So it needs an adapter.
