Getting distortion from speakers

[jackie c]

We have a Samsung Smart TV - UE46F6320 and are attempting to feed the audio through our Pioneer Integrated Amp model A-20K

We have used the optical input in the TV, but as the amp does not have a facility to connect to this we have bought an off board optical D/A converter. Although we are getting sound the bass is extremely distorted.

So, we have used a different amp to make sure it wasnt the Pioneer, results were just the same. Also, we have changed the phono cables from the D/A converter to the amp, same result, we have checked the speaker cables, all tight and have been working perfectly ok until this problem (Tannoy 636's floor standing)

The TV does not appear to have the facility to connect phono to phono, hence the use of an off board D/A converter.

PLEASE....ANY IDEAS? What are we missing :-(

Many thanks

I would have thought that the audio left & right out from the tv to the amp on 2 phono connections should work. It seems to suggest this in the Samsung manual on page 13.

we tried that and still got the distortion, thats why we are confused, we tried every possible connection, tightened all the connections from the speaker cables etc etc... at a loss to be honest :-(
