Morgan Smith BBC SCA1 - digital passthrough upgrade possible ?

[Mr.Ian]

After some 8 years I have another BBC SCA1 here, large and functional some might say pig ugly these make for a brilliant pre amp. They offer the sound quality of a top end pre-amp, listening today I think its ahead of my Toft LB5PA and my John Wood Valve pre amp and its switching flexibility is comparable to an AV processor

6 inputs are switchable between analogue, toslink and Digial Coaxial with seperate record and listen circuits. The record circuits feed the digital input to multiple digital outputs - both toslink and coax.

I am thinking by feeding the digital record outputs to different dacs and then back in on the listening circuits one can switch between dacs, digital room processors and the like but here's the problem

It only seems to pass 44.1khz and I guess 48khz. when I tried it with 24 bit 96khz and 192khz and all I got was crackling and popping.

As far as I can tell the receiver/transmitter modules are specced at 15mbs which I think should be enough for 192/24 so I am thinkimg there must be some more processing going on. There are loads of plug in IC chips on the board is there anything that might swap out to give me 96/24 or even 192/24 pass through ?
