Ears On

If there is a god, and he has a drawer full of headphones, this is what it would look like if the contents of that drawer were strewn along a very long table. I got in some face time with the new Grado Reference 1000 ($995) and it was like wearing a concert hall on my skull.

The largest meter at the show belonged without question to the McIntosh MC2KW power amp. It costs $30,000 but think of the money you'll save on lighting.

The Consumer Electronics Show doesn't start till next week but news is already leaking out. The first dual-format DVD player, handling both Blu-ray and HD DVD, will be announced by LG. Solving the same problem from another angle, Warner will announce a hybrid disc covering both formats, so you early adopters with single-format players needn't fall on your swords (if other studios fall in line). Perhaps the best news of all is that non-portable audio sales may be recovering after a long period of sitting in their room and moping. November figures from the Consumer Electronics Association show home component sales rising a whopping 54.9 percent, beating the 27.2 percent increase of iPods and other portables.

Would I stoop to running a news item just because it comes with a cool pic? If you thought otherwise, how little you know me. Congratulations to the Blu-ray family on the birth of the quad-layer disc, first shown in prototype at the 2006 International Consumer Electronics Show. Existing Blu-ray discs (inasmuch as they can be said to exist) use a single layer for capacity of 25 gigabytes or two layers for 50GB. Double the number of layers yet again and what do you get? A 100GB quad-layer disc that can store up to nine hours of high-definition video, at least in situations where digital rights management would so permit. As the picture shows, the disc actually has nine layers if you count the spacers, the second-from-top cover layer, and the Durabis layer—that's the name TDK has given the specially formulated top layer. Blu-ray players read data at a much shallower depth than regular DVD, so the top layer has to be both thin and hard. Otherwise it would need a protective caddy, like 2003-vintage Blu-ray in Japan. The quad-layer prototype is a write-once disc (not rewritable) and there's no word on when it will become available.

Last week I greeted the somewhat tardy arrival of Blu-ray and HD DVD to my rack. Happy happy joy joy, as Ren & Stimpy would say, but what to do about my reference receiver? My beloved Rotel RSX-1065 (and its seven-channel equivalent, the 1067) has no HDMI inputs. And regrettably, Rotel tells me it has no immediate plans to update its receiver line for HDMI. That means there's no way to get the new surround codecs into the receiver by a digital path at full resolution. As the magazine's audio editor, I am more than eager to hear lossless Dolby TrueHD and DTS-HD Master Audio. I'd also like to plumb the potential of the new & improved lossy formats, Dolby Digital Plus and DTS-HD High Resolution Audio. The only way to get them into the Rotel at full resolution was via the receiver's 5.1-channel analog inputs, relying on the player's built-in surround decoder. That took care of the Pioneer BDP-HD1 Blu-ray player, and I threw in a digital coaxial connection to continue feeding the receiver's old-style Dolby Digital and DTS decoders. But even if I'd been willing to swap six analog cables from player to player, the Toshiba HD-A2 HD DVD player has no 5.1 analog-outs! I had to settle for the digital optical interface, which handles the new codecs at reduced resolution as a backward-compatibility move. This introduced me to a quirk of Toshiba's HD DVD players, which is that they convert Dolby Digital Plus into PCM and then transcode it into DTS. Thus the optical connection lights up the DTS indicator on my receiver even when I'm not playing a DTS soundtrack. Having at least temporarily licked my connectivity problems, I set about upgrading the firmware in both players. Details next time.

In the three previous Rack Attacks I discussed getting, connecting, and updating Pioneer Blu-ray and Toshiba HD DVD players. Now what surround goodness can I get now that I've updated them? Let's start with the Pioneer. Just when I was girding myself to write a longwinded piece, half the information dropped into my lap in handy chart form. (For larger text size, see PDF or JPG.) One surprise, as the Pioneer product specialist explained: "The player internally decodes DolbyTrueHD into PCM for transmission over HDMI. The BDP-HD1 does not have HDMI 1.3 so it cannot send the bitstream over HDMI to be decoded in the receiver." The same is true of Dolby Digital Plus. However, footnote 17 has some good news: Depending on the number of channels, the PCM sampling rate can be 48kHz, 96kHz, or 192kHz, presumably without compression. So even converted to PCM, the new codecs may produce audible improvements over the old ones. Alas, the situation is not so sunny for surround buffs eager to experience DTS-HD Master Audio and DTS-HD High Resolution Audio. Go down the left column five rows to DTS-HD. Footnote 15 has this bad news: "DTS sound is output." I discussed this with the DTS people and they agree with my suspicion that this means the thing being converted to PCM is not DTS-HD MA or DTS-HD HRA but the lower-resolution DTS core signal. Sigh. Now, what's the story with the Toshiba? Find out next week.

Finally peace settles over the rack. I know what my Pioneer BDP-HD1 and Toshiba HD-A2 can and cannot do. Am I satisfied? It's great to know I'll have access to Dolby TrueHD and Dolby Digital Plus, even converted to high-bit PCM, but irksome to realize that firsthand experience with both forms of DTS-HD at full res will lie in the future. And what about the future? At the recent CEDIA I saw players that move forward into new territory, offering bitstream outputs of the new surround codecs for decoding in a receiver. Pioneer introduced the second-gen BDP-95FD ($1000). Of Toshiba's three new third-gen players, only the HD-A35 ($399) outputs the bitstream, and I'm shocked, shocked! that the other two don't. The HD-A35 is also the only Toshiba with a full set of analog-outs. At CEDIA there were many compatible receivers from Denon, Integra, Marantz, Onkyo, Pioneer, Yamaha, et al. Got one in the rack already, with another waiting in the wings, but how tantalizing it is to realize that the full surround capability that would transform my work as a reviewer is still two player swaps away--waiting for the next generation of rack attacks. In the meantime, I've never seen a better picture.
