Collection of mods for Beresford TC-7520

Nah, it's the big 4-0 lol.

Tell me about it

Anyone with a set of those cans know how hard it is to get decent bass out of them.
If you are looking to improve that situation, then the THS4032 makes an ideal partner for the K701.

Hi Stan, I have recently bought a second-hand pair of AKG 701s. I have both a Caiman and 7520 (love both of them) and wondered if you had any experience / thoughts / recommendations on which combination of DAC/Mods/Opamps would suit the AKGs? I have not done any mods to either DAC yet apart from changing opamps.

Any help is much appreciated.

Thanks

I think post #5 on this thread answers your question.

Ha.

I was after more.

Are there any of the mods that are worth doing. Also, I noticed that several have said that the THS4032 on the Caiman was a bit fatiguing...

I'm happy to play around myself, but if anyone has had good experiences with their experiments using the 701s I'd love to hear about them.

Hello everybody!

This my first post here

I have 7520 with new PSU. I use it only with my headphone Denon AH-D2000.
There is said here that:
"LM4562 fitted for the fixed output, Stan recommended removing MLC5 / MLC6 ceramics if using this particular op-amp"

What if I use only headphones? Can I put LM4562 to headphone output (on right site) and remove those ceramics or this mod (LM4562 to fixed/variable output and removing ceramics) is only for using with speakers?

I'm not good in soldering so this mod for me will be rather permanent
Providing it is possible for headphones, is it good mod for my Denon which are known for a little bit boomy bas (a bit out of control)

If you are staying with the PCM1716 DAC, then I fully recommend cutting the MCL 5 / 6 and putting dual 4562NA opamps in.

I got the WM8716 DAC done by tirna, and have just polished off the 36k mod on the caps, bringing them back into the loop. I found it significantly lacking in bass with the MCL 5 / 6 caps cut.

If I'm honest, I preferred the 1716 with MCL 5 / 6 cut, and dual 4562NA.
The WM8716 is totally unforgiving when it comes to recording quality and mastering.

And Mikes cables amplifies this too.

Who is Mike? Fairly sure I don't have his cables...?

Big thanks to Tom for his assistance with my AKG K701 question.

I performed the MLC5/6 mod and stuck a 4562 opamp into the headphone socket. This is a great combination with the 701s and really makes them sing. I have also experimented with different opamps in the lineout socket as I understand that this has an impact on the headphone sound too - have eventually settled on the THS4032 because it seemed to add a little extra to the low end grunt.

Very happy. Not intending to change this combo.
