I received my Analysis Plus digital coax cable this week and inserted my Pioneer Elite DV-58AV universal player (modified by Ric Schultz)to use as a DVD-A and odd format transport, feeding into the Playback Design's digital input and DAC.
First, I played every DVD-A that I own. Most are 24/96 but "iRobot" is 24/192. The PD had no trouble locking into any of the DVD's signals. For a while I kept the analog-out of the Pioneer hooked into my Rowland integrated via unbalanced RCA so that I could bypass the PD and truly compare the two. Well, all sounded better through the PD, even "iRobot". I wasn't sure what to expect because when the digital signal was captured the screen would change from "44.1" (expecting CD I guess) to "COAX 48kHhz", even with the 24/192 disc. I'm not sure what was going on and I guess I'll need to write Andreas unless someone on the forum knows. I suspect that the sampling rate may have been limited to 48 kHz by the Pioneer. I can't find anything clear in the Pioneer's manual and specs, regarding its digital output; however, it says under "Compressed Audio Compatibility", "Sampling rates: 32 kHz, 44.1 kHz and 48 kHz." So, I suspect that's the highest digital-out offered by the Pioneer, no matter the disc's capacity.
Let me talk briefly about Redbook, where I'm certain there's no down-conversion, just straight 44.1 into the PD's DAC. I used three cuts off Jennifer Warnes CD "FamousBlueRaincoat" listening to "Joan of Arc", "Ballad of the Runaway Horse" and "If it Be Your Will". Those tunes give quite a range of deep bass, great vocal, atmospheric out of phase images, depth and width. Earlier in the thread I talked about the Pioneer's Redbook vs. PD. It was no contest, with the Pioneer showing a much smaller image in width and height, much less richness in the mids and deep bass and all made worse with a glare over the top. Using the Pioneer as a transport and running through the PD's DAC really narrowed the gap dramatically. The main difference was in solidity of bass and the image size was now only slightly smaller when using the Pioneer transport vs. the PD's Esoteric transport. It was actually very good and would put the Pioneer in a top echelon. Said in other words, about 90% of the gain from the MPS-5 is in its DAC. Using a fairly mundane transport gave me much of the gain of the full MPS-5 treatment on Redbook. The PD's Redbook performance is truly astounding, lagging only slightly behind SACD (see my separate post on that matter elsewhere in this thread).
With DVDs the story is a little different. The sampling rate of the DVD didn't seem to matter. I found the "iRobot" final cut "Genesis" was astounding on my Pioneer. It's very thick and complex, with lots of out of phase signal creating a huge 180-degree wide image. When I ran that DVD through the PD's DAC, the image got taller and the bass got more solid, but it wasn't anywhere near as dramatic an improvement as with the CDs. The Pioneer is actually a pretty darn good DVD player. (Remember, Ric Schultz beefed up the input and output stages and put in a Superclock 4, among other things). Still, there was a major gain from going through the MPS-5's DAC.
Unfortunately I ran out of time before I could mess around with music via USB. I'll try to get to that in the next week. Hopefully when I plug my laptop into the MPS-5 it'll recognize it the laptop as a player. I've never sent a music signal out the USB, so any advice would be welcome. (It's a Windows PC running XP with Media Player installed. I can easily add another program if needed). I'm not sure how valid this'll be, because I assume that a computer music server will have a much higher grade sound card.
