From http://ultimateavmag.com/features/807hdmi13/

Read the full article for more detailed info. But here's the conlusions:

"What This All MeansFor Now

The conclusion about this sometimes confusing situation is that these first HDMI 1.3 players cannot pass either Dolby TrueHD or DTS-HD Master Audio to an HDMI 1.3 receiver over HDMI in full resolution bitstream formeven though this is a stated specification for HDMI 1.3. This appears to be a limitation inherent in the first HDMI transmitter 1.3 chips [a limitation that appears, in initial testing, to apply to Sony's PlayStation3 with regard to Dolby TrueHD, as well -Ed.].

Information we have received suggests that there are now new or modified chips that can do this, but we're not aware of a player currently available equipped with the new chip. That applies to the two players here, both of which were clearly designed and built months ago, well before new chips were available."


I think this will further delay some high end audiophile surround processor companies from implementing HDMI for multi-channel audio while this is sorted out.

the Toshiba XA2 passes bitstream HD audio using its 1.3a interface, I assume the toshiba A35 will as well once it's released.

Some BD players do too, most notably the 1400 from Samsung and perhaps others. So the chips are out there and are in devices that have been shipping for a few months anyway.

This simply emphasizes what we already knew... those with high end pre/pros are only need HDMI 1.1 or HDMI 1.2 LPCM via HDMI as a holdover until all this gets sorted out. Remember, LPCM over HDMI 1.1 will sound identical to bitstream passed over HDMI 1.3....so who needs HDMI 1.3?? Fortuntately Halcro and Lexicon have filled this need.

There are more than a handful of [op amps] that sound so good that most designers want to be using them as opposed to discreet transistors. Dave Reich, Theta 2009

I've seen on post that suggest jitter may be higher transmitting LPCM over HDMI than passing bitstream. Look at the Lumagen Radience thread.

Never become so involved with something that it blinds you.

Jeff,
How is your ssp100 performing after the latest updates? Glitch free? Also, how does your ssp100 compare sonically in 2ch and surround compared to other high end AV processors? Thanks.

Jitter in the context of HT, to me, is immaterial.

Addidi...I am eagrly awaiting it to be shipped.

Prior to the upgrade, how did the SSp100 compare to Meridian 861, Theta w/extreme dacs, any idea? Was the sound bright? Thanks.

The samsung 1400 can pass bit stream.
