That is... sub-optimal.

Off to faff about with hideously expensive HDMI to SPDIF extractors, then, and weed through the morass of 2-channel analog out plus TOSLink devices clogging the search results. Feh.

The only thing which comes close is an HDMI to 4 AES/EBU extractor -- only $2400! If you can find the bloody thing, that is. Yay.

HDMI-2A - ARVUS

Everything else has TosLink for multichannel -- compressed of course -- and RCA analog outs for downmixed two channel.

If anyone else has a better idea I'm all ears.

I do not follow this thread but, if it is relevant, there is a nice 8 channel USB-AES3 IO from miniDSP, the U-DIO8.

I could cobble together an HDMI to 8 AES output kluge from various silicon vendors' development boards, but every one of them cautions that'd work only for non-HDCP streams. Near as I can figure USB isn't crippled with copy protection / user harassing -- yet -- so USB interfaces are a relatively clean design.

In other news Arvus tells me the HDMI-2A does work with HDCP streams, and it's $1750 plus shipping from New Zealand

I think what you mean is

" That doesn't match my requirements "

Consider that it has no HMDI or video related input at all.. you do seem to be hung up on the fact that its I2S input uses the same connector as that used in video connections... however it is an I2S input for I2S. A similar situation would be if someone saw lots of XLR sockets on the rear of their analogue pre-amp and was complaining that none of them were AES/EBU digital inputs.

I mean what I said. With all due respect, the unit is 95% of the way to filling my requirements, so if the HDMI connector doesn't extract audio streams from video then the specs are suboptimal for my use, not a show-stopper since I've already found an alternate solution.

In any event, T Bass looks to have something rather nice. Ta!

It's gotten better, even though my engineering skepticism is yelling burn-in isn't real. Perhaps I'm hearing stuff not obvious from the git-go since my ears weren't used to the unit.

Anyway, the system's grown a newfound sense of s-c-a-l-e. Cool Struttin' by Sonny Clark lives quite comfortably in the room, as do Joni Mitchell, Joe Jackson, Bittersweet, and lots of friends.

Now remember the speakers have one RS-150 and one 27TDFC each. A demo to a fellow working on the house provoked the question "Where's the woofer?" "You're looking at it" He was gobsmacked, a testament to nCore's ability at plumbing the depths with aplomb.

Once again, well done. Even the chassis is brilliant, with the front panel and power button setting the right understated tone.

Thanks for the extra enthusiasm

I've got these amps up on my website now for those who are interested. I'd rather not start a discussion about the amps on someone else's thread though. If anyone is interested I had a thread here or I can be PM'd

Thank you should also go to David for bringing the attention of you guys, his potential customers, to my amp. Thanks.

Hi, Im not sure, were the project stands to go into reality, I dont went through the whole chat, but:
if I can help funding this to get it going, Im very interested as well, its sounds unreal good, that finally a HighEnd DSP Preamp might be available.
Kind regards Lars
