you can go for the updated yamaha yht 299 and connect via HDMI it would work like a charm. SPDIF can only handle 1500kbps audio (DTS)
DTS HD MA has much higher bit rate for both a/v goes upto 4000 - 5000
that's y they have high speed rated HDMI cables buy any good belkin cable
as for yht 196 it don't support DTS HD MA as its an older entry level htib
yht 299 could be bargained for around 35k if ur planning to upgrade
if DTS works fine for you then you can just follow previous post for spdif cable best option
