I would be surprised if the analogue and digital outs on the SDP-55 could be used simultaneously in a mixed fashion. Seems to me they would be two separate pathways, but you never know.

It could be done using Dante to XLR convertors but I did a quick search and, at least for results I found, I would be concerned about the quality of the DAC's in those convertors. I doubt they'll be the same quality as those in the prepro.

That would be a shame, and IMO make the feature useless for most people. The primary use cases I see are
1) Dante -> front or bed amps + analog heights
2) opposite of above
3) analog main zone, Dante other zone(s)

My thought is opposite - just like the Marantzes ask if a channel is XLR or RCA in setup, I’d expect the JBL to ask Dante/XLR/RCA.

IMO this prepro lives or dies on the worth of Logic16 as a 2ch upmixer regardless, but Dante if implemented well is a nice feature too.

A lot of Crown in Indiana talent bolted Harman after the Samsung takeover to form their own amp company. I don’t remember the name off hand but IIRC their focus is network enabled amps.

Nah... This AVR is squarly set at the "Pro" crowd and I can't wait
Dante will be used when the AVR is in studios, theaters, labs, live production, and event venues which use consumer playback devices and HDMI Audio extraction is needed.

Seems to me those with active speakers and/or that own amps with DSP are an exceedingly small group, and those mixing analog and digital even smaller. Wouldn't seem worth the development costs, but just a guess.

Would be cool if you're right. We'll see soon enough .

Was just informed there be “crossover by pairs”.

Will try to get more details.

Interesting, I would have thought the Dirac Live Bass Management module would set the optimal crossovers on a per channel basis as part of the measurements/calculations.

"By pairs" would be the right way to do it. That is the way D&M does and also Emotiva.

Even righter would be by individual speaker, since bass rolloff freq in one of the pair could be very different due to asymmetric placement, which many of us are stuck with.

I don't know if I'd agree -- while it may be right in one sense, it may be wrong in another. Would a left speaker crossed at 40hz and a right speaker crossed at 120hz have similar tonality? I'd think, for example, an 80hz sound moving from left to right would get screwy. Now, I don't know if that's a realistic difference (40hz vs. 120hz), but if it's closer to 70hz vs. 80hz wouldn't it just be better to pick 80hz for both and be done with it?

OK, you convinced me

Also might give better-matched phase response between the two to have the XO at the same phase freq.

Dirac has mentioned somewhere about phase matching speaker pairs.

I think these prepros are nailing everything critical for me. I can't think of anything worth an extra 10k+, that's for sure.

A Members Only Trinnov jacket paired with a set of Top Gun sunglasses is surely worth $10k, no?

No jacket, no sunglasses, but you do get the most configurable RC on the market. The vast majority of folks may not need/want that, but some do.

It seems like Elan will be making some amps implementing Dante:

I am sure this has circulated by now but here it is again...
Note I am not sure if this will be part of future firmware or a billable option at this time.


Dirac Live Bass Management Makes Residential AV Market Debut at CEDIA 2019 August 21, 2019

Dirac Live Bass Management aggregates measurement and location data from each subwoofer to determine how a system’s bass is distributed throughout the room. It then identifies gaps in the sound waves and distributes bass evenly across the room. Furthermore, the solution corrects the low-frequency sound waves produced by the speaker pair, so the bass produced by each speaker is in sync with the system. All of this processing enables the subwoofers to be positioned anywhere in the room – wherever most aesthetically pleasing – without sacrificing performance for design, or vice versa.

Dirac Live Bass Management, the first in a series of modular add-ons for Dirac Live, is available in two versions: Single-Sub, for single subwoofer home theater systems, is priced at $249, while Multi-Sub, for systems with more than one sub, is priced at $399.

The M10 BluOS streaming amplifier and C658 BluOS streaming DAC will be the first two products from NAD to feature Dirac Live Bass Management. Depending on one’s specific system, customers will have the option of purchasing the Single-Sub or Multi-Sub options. StormAudio is set to incorporate Dirac Live Bass Management into its full line of processors and amplifiers while Arcam and JBL Synthesis are slated to incorporate it into the majority of its AVR product portfolio.

"Whether an audiophile, a movie buff, or a casual TV viewer, every customer deserves the best performance from their system,” Thorin concluded. “Dirac Live Bass Management delivers just that, and we are excited to showcase it to the residential AV market at CEDIA 2019.”

As an FYI for those comparing to the Monoprice HTP-1, I emailed them and asked if the assignable speaker outputs include active crossover and delay settings and the answer was No.

Still trying to find out if the SDP-55 can though as my front 3 speakers need active x over inc parametric EQ & delay applied.
