Anyone finished burning in their TC-7520 yet?

The ebay seller has just send an email thanking me for the purchase and put that the LME49720HA is even better-what do you think?

I used the LME49710 on my Alpha DAC experiment and was very impressed.

Does changing the opamps only change the sound of the headphone out ?

No

Apologies , i do not come from an electronic background .
So If i understand correctly , By changing the opamps one could expect a difference in sound from both the fixed and variable outputs ?

I'm no whizz neither. Stan will know better than me but I think ones for the fixed and the others for the 'phones?

Hi Stan - Did you try the OPA2132 against the LM4562 and THS4032? If so how did it compare?
Is the 2132 a step in the right direction from the stock 5532's?

Has anyone else tried rolling any other opamps in a TC-7520?

2132's are fet input based, they tend to be a little dark and smooth sounding if thats your thing they have lower DC offset than bipolar but if the dac uses DC coupling caps thats no issue

THS4032 is a very very good chip, as long as its stable in the used circuit (it don't like unity gain circuits even though its claimed to be ok ), this chip is almost identical topology to the AD826, just a small difference

AD826 is good at driving headphones too

Thanks Leo - I have some 2132's - I'll give them a try.
Would you prefer the THS4032 over the LM4562? - I assume they are stable in the TC-7520 as Stan has already commented on it. They are both more or less the same price (except for the adapter) but I don't want to fork out for a couple of chips unnecessarily.
