Is anyone going to re-hijack this thread?
op amps..MCL7?
I can see the lips moving but know not what it all means.
you could always start a new thread " mod your TC-7520" so that modders post there and leave this thread for comments on a burn't in 7520. your quite right in what you say, i being guilty as everyone else when i haven't even got one in the first place!! :doh:Quote:

Apologies SteveW I think it was me who got it off on a diversion.Quote:

Agreed regarding moving the modding stuff to the diy section, don't think I can do it on this part of the forum though:)
OK Leo, understood - Thanks for that. I have the OPA2132's installed at the moment and I like the sound. I wouldn't say better than the stock chips, just different in a way that I like. The order is in for the THS4032's - Fortunately I have some BrownDog's.
Also, appologies for adding to this thread - Please feel free to move it to the DIY section.
Cheers - Ken
Its OK guys..just looking for rave reviews so that I have an excuse to get my credit card out again for my third standac !
Care to elaborate on how the sound differs with the 2132's ?Quote:

The stock 5532 chip works great with the HD600's but with the K701's can sound a bit light with a hard edge in the upper treble at times which doesn't encourage a long listeneing session - A bit tiring.
However, the OPA2132's have the typical "Burr-Brown sound" - Slightly darker but (to my ears) more nicely rounded. The hard edge is gone but the detail and clarity is still there - Exactly why I bought the K701's. I'm no basshead but bass did initially sound less powerful - But I think it's because it's faster and less confused (does that make sense?). The overall effect just makes me want to keep listening.
The AKG's are not easy phones to drive and sound better through a (good) external headphone amplifier without a doubt, but every credit to the TC-7520's headamp - I am looking forward to trying the THS4032's.
Hope this has been some use.

Yes a great help , thanks for that , sounds like the 2132's might be up my street.
Found some of these on ebay
