any experience with TRL mod ?

Thanks for the info. I sent an e mail to paul. I am deciding whether to mod my Sony 333es which I like the sound of or my XA777es which I don't like the sound of and hope it's gets better.

Frano, sorry forgot to mention the conversion is of the highest order. The attention to details are second to none. Paul is a true craftsman that takes pride in his work. You won't be disappointed!

There's a new TRL 595 review at the following link, which might answer a few of your questions.

Thanks for the link, jes45. I've been waiting to see the review prior to making my decision. Maybe I should try the C2000ES instead?

Paul Wietzel of TRL told me that the modded 2000ES sounds better than the modded 595. Given that the 2000ES has a lot in common with the 595, its good that the extra $$ gives you better sound quality and not just better looks.
