Has anyone tried upsampling with the Panny?

Just curious in anyone has tried a DIP, GW Labs Upsampler or the Perp Tech unit with the digital input of the '45. I'd be curious to hear how that worked if anyone's tried it.

I'm planning to try software-upsampling some .wav files to do a 44.1 vs 96 comparision with my XR25 - hopefully within the next couple days. I don't have an external hardware upsampler box - I'll be playing the .wav files from my PC via an M-Audio Delta 1010 card.

The oversampling filter used in the TI modulator doesn't seem to be very good - it's only spec'd at 50db stopband attenuation - so there's at least some reason to think external upsampling might help.

Cool. I'm anxious to see how it works. I'm also wondering if the Panny will retain the 24 bit depth while applying DSP (primarily curious if you can upsample & apply PLII).

Does the Panny do upsampling to 24/192 khz on all external sources?

I just ordered a Panasonic SA-Xr45 and a Panasonic DVD-F85 DVD-Audio player from onecall.com.

Not in the sense that an external box does. The digital signal is passed to the Equibit modulator at whatever rate it came in at. Internally, the modulator will oversample this in a similar fashion to a conventional DAC, but doesn't appear to do it very well.

Hopefully you'll get it. In the last week or so lots of reports of the XR45 being discontinued have popped up.

I only have the XR25, and so I don't have DLPII, but I'll try Neo6. I think I remember Wayne saying you couldn't use party mode on higher-rate signals like the 96kHz pcm track from the Chesky DAD's, so processing might be turned off altogether.

The '25 does DPL 2.

I think there's been a run on the '45s - They are just outta stock. The replacement won't be out until the fall.

The DVD-F85 was almost impossible to find in black, although the silver was available.

I ordered the units from Onecall.com who I have ordered for and they have a pretty good reputation for honesty. But you never know until the unit arrives at the door. LOL.

Thanks for the info on the upsampling.

can the panny receive a 192khz source? i've read that it can take a 96khz input but nothing about 192khz.... I'm looking at two different soundcards for my computer and one can upsample up to 96khz while the other can upsample to 192khz and if the panny can only take a 96khz signal, i might as well save some money.

I just received the Panny 45 and I also purchased the Panasonic DVD-85F which itself has double remaster. When I have both the remater on from the Panny 45 and the DVD Player, the remaster from the 45 turns it remaster off, becasue the DVD player is sending a signal of 176.4khz, but I do not know the bit depth.

It appears as if the 45 will accept 192 signal. This is also eluded to in the manual.

So far the 45 sounds fine. The OSD is only active using the composite monitor output, and not the s-video monitor out. Weird.

As reported here and on AA, the 45 reads, excepts and even displays a 192hz signal from a player such as the Philips 963sa which actually outputs a 192hz signal from its digital out.

So any source that actually outputs a 192hz upsampled signal will work on the 45.

I was using a Assemblage D2D with the xr-45, the sound quality improves (detail, soundstage) at the higher sampling rates out of the D2D, both when used dierctly into the 45 and also upsampled to higher rates and then going through Behringer stuff before the XR-45.

Hi,
I use a Panny rp82 for video and Redbook cds due to it's re-master (upsampling) feature that goes to 88.2. I do not use the dvd-a portion of this player as I have a mltidisc JVC for that. The dvd-a has to be turned off for the upsampling to work.

There's also one small thing in the Panny's manual. It says to check to see if your prepro recognises 88.2 because although many recognise 96 most don't recognise 88.2. I use a Denon 5800 which only recognised 88.2 after the 2003 upgrade.

So do I, it's a very good match plus the RP82 has great video.
