BUT...

I have the 540R Av reciever, with Pre-outs and 6.1 direct In sockets.
From the web other folk have used the 540R as a poweramp, and if I can try my 7520 this way (even just as a test) It would be great.

Anyone any pointers how I can do this (if it CAN be done?)

Ta.

im not familiar with the 540r but you would just take a pair of phonos out the adjustable output of the dac and into the front channel inputs of the amp

my av amp only has multi channel in though which doesnt bypass the volume control.. it is just for allowing the dvd/sacd/blu-ray(whatever) decode on board then output analogue to the amp.

this would be what i would expect your av amp to have... but i might be wrong - as i said i dont know the amp in question - im just speaking from experience of similar equipment!

I am aware of his highly praised dacs, I just wondered what he may have been involved with before.

I mainly have an IT background but have always had a keen interest in audio. I have my dad to thank for that!

I prefer a satisfied former customer than an unsatisfied existing customer.

Stan,

If anyone feels the need to take you up on this offer will you in turn accept an offer of 50% off the full retail price for this now "used" DAC. ;)

My sympathies, Stan. You're a credit to the word "patience."

Thanks Hamish,
The 540R only has multichannel in as well, I wondered if I could just connect the variable out of the Dac to the front in sockets on the AV amp.
I guess its just the DVD player decoding that gives it output when using my main amp to drive the two fronts watching movies.
Tried it, no sound.

Ah well - need to wait longer till I try the Caiman as a Preamp!

Don't know the amp Gaz,but are there any audio options in the setup menu? It may be one of these would allow you to do what you want to do.

I have a wide electronics background. As far as the audio side is concerned, I designed the world's third portable mp3 player called the MPress3 in 1997. I also designed the THOR range of interconnect, and the THOR Automatic HDMI selector. I also designed the first decent IR headphone, and one of the first RF headphone approved for use in the UK. At the same time I designed the first legally approved consumer video sender for use in the UK. I was also the first to design an automatic SCART switch (1996). I was technical manager at a company called Philex during that time, so I got just my monthly salary.
That's just the audio side of it. I also designed some video and networking stuff.
Way before that, I was one of the first UK trained CD repair engineer in 1983. People like me were needed to be on standby for the release of the first generation of CD players. Later on I ended up as training manager for Lasky's repair department, teaching others how to fix CD players...

Hi Guys,

I have both a caiman (with AD826 opamps) and a 7520 (with THS4032 opamps). I have just purchased a second hand pair of AKG 701 headphones. I understand that they are low impedance but require a high current to make the best of them.

I was wondering whether any of you have experience of these headphones with either the 7520 or Caiman and have any recommendations. Will I need an additional headphone amp to make the best of them?

Stan must speak for himself, but he told me either the 7520 ore the Caiman will drive the AKG 701s well.

On Stan's recommendation I bough some Sony F1s and have not been disappointed.

I’m happy when listening via my AKG K701 headphones directly connected to the Caiman or the TC-7520 DAC. However, if I connect the headphones to my Yamaha AX-592 integrated amplifier the music’s punch and volume are increased.

My ears might not be the best; I prefer connecting the headphones to the integrated amplifier.

That what i thought when i purchased a Pro-ject headphone amp {incidently made in Austria ,Vienna!},that the headphone out on my nad amp had more punch and volume.

BUT once u start to listen with proper headphone amps u realise that the extra punch and volume from an intergrated amps headphone socket is only through lots more distortion

I'm finding my Caimanised 7520 DAC lacks some of the bassy punch and guitar growl the 7520 had before.

I'll report back once I've put the recommended 36k resistors in. Fingers crossed!
