Having weighed up all the pros and cons have decided to stick with what I have for now. I decided against directly demoing the Caiman due to the long burn in time it would never have performed fairly in a side by side test.

For now with money quite tight after buying all the gear I will leave stuff but in a month or so I will advertise on various forums (where QED is more popular!) the cable for sale and then buy the Mark Grant. Simarly I will buy a Caiman give it a full burn in period then sell one of the DACs.

The speaker positioning as made siginificant differences, I checked the manual and have adjusted accordingly.

Hamish. You actually pointed me towards dynaudio no monitor audio. I have never been to sight and sound. I actually bought the V-Dac online and everything else in a local HiFi shop 'Searle Audio' (in South Cumbria) I did not try the RS6's but did try some RS 5's, the RS8 sounded significantly better.

Finally, one question how important is terminating cable I just have cheap brass plugs at the moment on the QED. Does it make any significant difference putting something fancier like airlocks on. Whatever I probably will not do anything as I plan on selling the cable but I am still interested.

Thanks again
