Anyone finished burning in their TC-7520 yet?

No offense but you guys must have incredible ears , Its very difficult (for me) to hear the diff between the 7520 and my old CA AZUR cd player , i can hear it but only just.

I think the following plays a huge part in what we hear

http://en.wikipedia.org/wiki/Psychoacoustics

I just get VERY skeptical when people hear these huge differences between power supplies
And for your info ,i work as a pro piano tuner and musician so my ears are fairly good at listening.

Sorry if i upset anyone , the 7520 is a lovely dac for sure but c'mon get a grip lads ,,,,

Never heard the Azur but the 7510/7520 was a big leap up from my DV717 player, before the voices just seemed to float about inside the speakers, with the 7520 the singers voice gets locked in place and the soundstage sounds much larger. The unit is hidden behind the TV as there isnt any room on the rack at present and my wife had no idea it was even in the room much less installed on the stereo and she mentioned that the stereo was "sounding really good these days" When I told my wife I had installed the 7510 in the lounge she agreed it was a good purchase, she then asked how I was going to listen to my headphones in the bedroom....I then had to come clean to buying a 7520, then she wasnt so happy.

But as she had no part in the purchases and as she has no interest in hi fi she has given me some good feedback on both systems. She prefers the 7510 in the lounge as she doesnt like the extra bass from the 7520 but she picked the 7520 as having by far the best headphone amp.

On my system at least the 7520 has not really got the opportunity to shine given the budget components I use: DV717 dvd/cd player, Cambridge A1 Mk 3 amp and Tannoy Mercury F1 Custom speakers on Atacama SE24 stands.

As for the differences in power supplies, well I live very close to an industrial estate and during the day all of my kit sounds out of sorts, using the battery during the day has sorted it right out for headphone usage, at night the difference is nowhere near as pronounced.

And yes I do have very sensitive hearing, old crt tv's and monitors on their last legs drive me mad as I can hear a high pitched whistle that alot of others can't hear.

Yes I hear that too! Drives me nuts sometimes.

another thing to consider is the different surroundings and equipment we all use, some are in big rooms and some aren't (me = mid sized)....some have revealing speakers (MA Gold Ref 20 = quite revealing) others have more neutral gear.....some use headphones exclusively and therefore are probably more prone to heavy variance than those with speakers - there's alot of variables.

i wouldn't call the difference between the 7510 6/4 and the 7520 night and day (that would be foolish and a disservice to the 7510) but it's more pronounced than i expected with more bass and cleaner resolution all around - without waxing lyrical it's more energetic than the 7510.....i've certainly never heard MJ's Thriller album sound so lively. can't comment about the CA Azur as i don't own one.

i for one didn't state a huge difference when changing psu's but my first reaction was that bass felt a touch deeper, this could have been the actual DAC bedding in as i changed power after roughly 80-100hrs on the unit and until i have more time to test between the new and old it's hard for me to really gauge anything.

it's all subjective at the end of the day and i doubt you have upset anyone, only you and your ears are the things that matter.

I've just stuck a couple of 4562's into mine. Holy moly.

If these 4562s are so much better (and Stan himself said they are) then why aren't they fitted as standard on the 7520?

Cost vs performance

Cost vs performance

A single LM4562 can be bought retail for £4.99 on a quick search. Obviously it would be a lot cheaper in manufacturing quantities. That doesn't seem like a lot. Surely it would be worth it even if it meant the 7520 cost £4.99 extra

The DAC1 at several times the price of the TC-7520 also use the 5532.

I don't wish to create the illusion that one needs to dig even deeper in his or her pocket in order to get the TC-7520 to sound fantastic. The aim is to get it to be a serious contender straight out of the box. And if you wish to spend a bit more out of your own free will, you can leave the competition flat footed and show them a clean pair of heels.

Me three.....hate that sound. I can even hear the sound that a CRT makes when working hard to reproduce WHITE.

How big a difference did they make? I should have a pair waiting for me at work. Did you replace both socketed opamps.
