Yes, I have tried two types of opamps in my MHDT Paradisea.

LM4562 and BB OPA2107AP .

The 2107 has more weight and bold LF, Less detail & slightly muddy.

But I like LM4562 which has inner resolution, detail in HF, decay.


Thank you,
sunder.

The beresford caiman also uses the LM4562. The hf is very smooth, mids are almost 3 dimensional and forward but it lacks a little weight and heft in the bass although the bass is quite precise.

I want to try the TI OPA2132 in my Caiman. Obviously i will need someone's help..... Any diyer's in Delhi NCR area ?

I think the Caiman uses the 8-pin DIP socket for the OPAMPs (based on gut-pics from theartofsound.net forum) so you can actually plug-and-play. You just need to source the OPAMP (make sure it is a "dual" model).

Scroll down to post #24, made by Stanley, to see the pic I'm talking about.

The folks at theartofsound.net have a lot of detailed threads on Caiman Mods. I've been spending most of my free time going thought them over the last week or so. 99% of it goes above my head -- I'm a total non-techie -- but it is interesting to know what is possible.
