Can the AV40 stream multichannel (5.1) flac via Roon without downmixing to 2.0? Also, can it playback DSD files via Roon?I am pleased to report that there are initial signs of MQA 192Khz working. AV40 as roon end point. As decoder and renderer. It played the Neil Diamond Song sung blue track very well, but struggled with a lot of static on another.
I am pleasantly surprised about the 2 ch performance. Really good. I am comparing this to a McIntosh C2600 pre-amp/DAC. Again, not a fair comparison. I have not put myself to a blind test, but one will be interesting.
I tested that the optical output works. This is useful if you want to use an external DAC or external 2-ch tube preamp. Anyone know if there are other digital outputs on the AV40 like a USB/SPDIF? I have not had time to test the under documented connectors in the back panel. It is a pity if it has only optical as we are limited to 92Khz.
