you ever noticed little holes on double sided pcb's? those holes are through plated connecting parts of the top layer track to the bottom layer track.
If theres a via on the bottom of the little converter pcb going straight to those needed pins on the top layer it should be pretty close as long as the boards not too thick

I'm Tyrone.
Guys, the revised Tirna board does the job perfectly, I can quite honestly say it is a job well done and dealing with them has been a pleasure.
Outstanding, kinda expecting nothing less from these guys.
A+ ebayer I'd say.
Hopefully mine will arrive tommorow and I'll slot them in.
4562's are outstanding, if these are better..
cool.
Oh, listening to "Kind of Blue" for the first time thru the 7520.
Fekkin hell - your in the room!
Ok with not having it on Betamax nowadays

My apologies to everyone for causing confusion-Tirna have only refunded the postage to me. The revised op-amp arrived today so I will fit it tonight after I finish work.

popped in a LT1364 this morning, my o my what a revelation versus the stock opamps - it's like a new DAC all over again.
the percussion, seperation, soundstage, vocals .....all much improved and i expected some improvement but not this drastic. as some have mentioned they are quite forward in presentation but not overly and i expect this will tone down a little after a few hrs - glad i don't have bright amps though as i think it might be too much. the increase in detail being picked up is incredible to be honest.... guitars,cymbals + spatial sounds are off the charts.
got some 4032's on the way also so will see how they fare versus these 1364's.

The stock opamps are the same that are being used in other far more expensive DACs like the DAC1. It just goes to show how excellent the TC-7520 is in its basic design. By loading up a set of more refined opamps you can challenge a lot of other DACs. I wonder how a TC-7520 with THS4032 opamps fitted would stack up against the seriously expensive opposition out there.
I'd be really interested to see/hear a shoot-out between the modded 7520 and some £1000+ DAC's and the Linn Sneaky DS. My local hi-fi shop currently use the Sneaky as there reference system since it beat there old £5000 CD transport + DAC setup. If I get chance sometime I might challenge them to a duel.
I need to call in for a chat sometime soon anyway.
