Anyone finished burning in their TC-7520 yet?

But they are marked OPA2132P ,are they the same as yours ?

I tend to steer clear buying chips on Ebay - Farnell have them at £4.67 +VAT which is probably not much different than Ebay with P&P.

Mine are OPA2132PA - I dont think the differences are significant though.

Just been listening to some Santana - :) - You're going to love that Opamp!

My apologies, I did not mean to suggest that the 7520 was not a finished product but anyone stumbling upon this thread would understandably expect to see how happy users are with this new DAC, specifically after burning it in.

I appreciate this is an enthusiasts forum but this thread seems to have moved towards discussing the subtle differences between various OpAmps. My ears do not posess enough resolving power to fully appreciate these nuances I fear. I just would like to hear how many people are happy with the sound 'as-is' to start off with.

Unless someone discovers a killer upgrade by changing a resistor value or something similar I would leave it alone for 6 months or so at least.

I can see your point mrwarby but I suspect the differences between op-amps are more pronounced than say, between cables and look how audiophools argue about those!
Its only a bit of fun at the end of the day and its a tweak that doesn't cost a huge amount of money. :)

Another thing to remember is just because one opamp sounds great in one circuit does not guarantee happiness in another. The supporting circuitry has as much to contribute as the opamp and if it is designed to get the best out of one opamp another high end one might sound rubbish in that application.

And as for cables, I have never known a topic that has gotten people so worked up. The only thing akin to pouring petrol on the bonfire is then throwing in an opinion on double blind testing said cables...

Agreed - I guess that's why it pays to experiment. This is the fun of our hobby. Not forgetting also that people's hearing is different and their preference for a particular sound signature.

As for cables - There's no way I am going down that road!

Cheers - Ken

I second that. Experimenting is great and please share your experiences but not in a thread where you would expect to read how users think that their 7520-as-they-bought-it sounds after some burning in time.

I am not a technician so opamps could be a contagious desease as far as I am concerned. A thread like this one was great for me to read about the in terms that I understand. I hope the opamp-talk will be continued in a proper thread.

I've been listening to Radio2 through a SkyHD box this afternoon into the 7520.
Thought I'd give it a go. I usually have it going through the Arcam 350 then to the 202.

Far better through the 7520. Far more reailistic and detailed and very good considering the low bitrate.
