Hi Ramy I have a vsei modded sony scd-1 that does not require a dac.The signal is in pure dsd with a low pass filter.Can I still mate this with a meridian 861 and utilise the trifield mode.I understand the 861 only splits the digital signal.I have been using the Levinson 380s preamp with no problems.I use atc asl 150 pro speakers from our friend Doug.
