So aside from the opamp swapping, anyone have any bright ideas for bettering the analog output stage? The DAC swapping is all well and good to me, but really, the digital section isn't near as important as the analog portion.

The op-amp swapping has nothing to do with DAC swapping.Quote:

Chris;)
I cited the DAC bit just as a way of showing that the digital section means less to me than the analog.Quote:

Why cite the DAC thing at all ?Quote:

At least that's the way I read it.

It is very easy to be big and brave and "clever" anonymously.
I suggest you get yourself a decent therapist and stop coming out to play with normal people until you have sorted out your own personal issues.

Here Here to that but I strongly believe that it could justifiably be stated in much much stronger language.:steam::steam::steam:Quote:

Move on and see if you can find somewhere else where your attitude would be more welcome!!
Sorry to sidetrack this rather abrasive gent's contributions, but hello!
I picked up the TC-7520 from Stan on thursday.
I took it home, got it running in while I was out for the rest of the day.
On friday evening I finally sat down to give it a good listen and was a little disheartened. The stock opamps really didn't tickle my fancy at all.
To put this into context, I've been using a PC-attached breakout box, while not able to properly drive my K701s it did manage to convey incredible timbre and with it the ability to pick out instruments easily. It had practically no bass, channel seperation or soundstage. Like listening to a very good oil painting.
The Stock TC-7520 re-introduced the bass wholesale to the mix. It was present, not too dominant and fairly well balanced, but the fidelity was lacking. There was some distortion initially on busy pieces of music (mostly rock) but that cleared up within 24 hours. I found it hard to get into the music as I had before, usually I would sink into my chair for an hour or so with a good album on. This did not happen.
I had ordered the 4652NA's before I had even picked up the unit, based on the findings earlier in this thread.
I popped them into the unit a few hours ago and was considerably happier with the sound.
The stage is wider, presence is improved, easier to pick out individual instruments, and the rhythm is perfect (to my ears). Listening to Cat Stevens - Oh Very Young is absolutely beautiful in terms of arrangement, detail and delivery of rhythm. Hairs standing up on the back of my neck. The detail of all the little things going on in the music are available - Someone humming along during the piano solo always makes me smile.
Edit: I thought it was just the recordings but I've noticed a real sense of veil or mono-tonality with the 4562's, hopefully this will disappear in time (Or my ears will learn to deal with it, whichever is sooner ;) )
I'll end this review by saying this is an absolutely brilliant piece of equipment with the 4652NA's installed, nothing comes close in terms of price / performance.
There is still a nagging doubt in my mind though. I miss the timbre of the first unit, and with it, the ability to really follow an instrument through the music.
Will installing a THS4032 opamp on the HPA circuit provide this? Are there alternatives?
Or should I save my monies and attempt the MCL5/6 mod?
To all those who have contributed to this thread, you've been an invaluable help and I look forward to what you come up with next. :)
Hi Zebu (may we shorten it to Zeb ?),:)
Welcome to the forum - nice first posting and a welcome cotribution to the subject of the thread. I'm sure others more knowledgeable than me will be along with their two penn'orth shortly. Meanwhile can I be the first to pass you the obligatory first request(s): -
1) please post an introduction in the Welcome area of the forum, preferably giving details of your first name (we like first names on this very friendly forum) - (there will always be exceptions to the friendly response if we feel that it isn't being reciprocated, as you have obviously already noted!);)
2) please include detais of your audio set up and your tastes in music - what do you like listening to?
3) if possible can you post pics of your set up in the gallery area? - we also like pics on this forum.:)
Again, welcome - may your stay be a long, friendly and fruitful one.
Cheers,
Welcome bovine one, good to see someone on this thread actually interested in 7520-modding rather than lingling-modding.
Everyone's ears and kit are different, but its certainly worth trying the 4032 as they're only about a tenner and easy enough to fit. For me they expanded the bass, banishing that same mono-tonality you've just added (assuming its just in the bass you have that problem) and maybe slightly added a little detail to the treble.
A few weeks ago Stan said it should soon be possible to buy a spare opamp board. I'm hoping that this will allow the soldering impaired amongst us to try the MLC5/MLC6 mod out without preventing a return to using the 4032, may be worth waiting for that before snipping anything unless you're comfortable soldering. (Can you confirm this Stan if you see this?)
But from what I've read so far, the MLC mod may well be the mod to go for for the sound you're seeking - though I've see very little discussion of the effect that has on the bass.
