Default OPA2132PA in Shanling Cd T80

Hi guys. I've decided to upgrade the stock ICs in my Shanling Cd T80 to OPA2132PA's

A few questions to help me:

1) How many Do I need?

2) Will the OPA2132PAs simply install in the same IC socket after I pull the old ones out?

3) Do I buy the Single, Dual, or quad versions?

4) Are all the OPA2132PA's the same sonically? Does it matter where I buy them?

Many thanks for all your help.
Retro.

I don't have a CD-T80, but from what I can gather from the web it contains three OPA2604AP. Replacing these with the op-amp mentioned should work fine.

You can get samples of OPA2132P/PA from TI. I have some other op-amps that would work well, some of which can't be sampled (OPA2134PA, OPA134PA on browndog adapter, OPA2227). I also have LM4562 which is a nice op-amp.

Default Thank you

Thank you for the response.

So, it looks like I should get three of the replacement Op amps?

thanks.

Yes you need to order three OPA2132PA's for your Shanling CD-T80. They sound really good in this CD player. You might also want to try the LM4562's as well for a more neutral sound. I'd say the OPA2132's are better for Rock/Dance though.

At some point look into changing the cheap output valves too. I'd say that made more difference for me than changing the op-amps.

Thank you John.

Actually I have already replaced the stock valves with 1952 GE's, which sound awesome.

Thanks again for your help!

John, I just remove the old ICs from the sockets and install the new ones, right?

No other mod is needed, is that correct?

thanks,
Mike

Wow!! All done and sounding GREAT. Hard to believe...a 15$ upgrade and 15 mins work to improve the sound of an already great Cd player.

Thanks John!!
