Hi banause...that is sposed to be a good op-amp..let us know how you get on....on a slightly different note, I have just recieved my tentlabs xo, so I will report back once I have fitted it.I will use an internal 5vdc source ( not the existing 3.3vdc ) from the reg just until I build a suitable supply.

Sent, be very careful, if this does not work I also have 5 x new boxed lasers, for the HD-970 and I also believe the HD-990 is the same, package deal for the lot $150usd + post (paypal).

Cheers George

this is how i managed to get bitperfect digital sound from usb.

i bought one of those usb to spdif units from china (ebay)
it uses burr brown pcm 2906 which is considered to be better than other brand usb-chips concerning jitter.

on windows xp i'm using asio4all as driver and i get the real 44,1 instead of 48khz

nice!

Default hd 970 usb

did some work today...
i soldered the browndogs with the ad 797s and i integrated the usb pcb... so now it's a hd 970 usb

i kept the rca sockets and connect with a wire. so it still can use other coaxial sources.

now i'll give the 797s some days to burn in before i compare to my stock hd 970 and a arcam cd192 of a friend.

george - thx for sending the files...
it seems they all are files for the version 1 player

both of mine use sanyo hd65 laser.
but i fixed them by getting a new laser pickup.
changing the whole laser unit did not work in both cases because of firmware issues... just changing the laser pickup worked fine!!

Default HD970 not reading many CDs

Hi,
I saw that my HD970 may not be the only one that cannot read CDs. Actually it can read one out of five CDs that I throw at it.
There seems to exist a software update that solves the problem?
Where can I find that update and how do I upload it to the CD player?
(I know very well my way around computers, but I am not too much in hi-fi modding).
Thanks in advance

first make sure which version of the player you have.
check picture!

if you have version 2 you'll probably need to get a new laser pickup

if you have version 1 you can try the firmware update
