the RME is modded (power rail caps and looking to possibly tap i2s from it) but i've become interested in buying a denon SACD player, upgrading the power supply and modding it to supply high rez DSD to the buffalo32 and also using it for movies of course. now how much of an improvement will I see do you think?? I mean i'm not looking for percentages or anything like that, but a nudge would be great. I can already realize hires out of the MAC and the convenience of having all my tunes at my finger-tips is great, I wont get rid of this as an option, I will simply use the denon as another input. but is it worth the time/expense??
thanks in advance, looking at a 2900 or 2910
From the analog outs it's a good jump up in SQ but it's tied to recording quality more or less. The great SACD recordings will sound terrific. Any upgrades to a units PSU is a good idea in my book. The beating heart of the beast is the PSU IMO...improve this and everything down the line reaps the benefit
I plan on improving the 3910's PSU sections when it arrives next week among other projects currently on the go. I'm not sure you can tap the unlocked DSD stream from inside the player. I'm taking a guess here but I bet the stream is hardcode locked inside the SACD/DSD processors with the only data link approved for use being the iLink pathway. It looks for a Denon ID string to shake hands before enabling the stream to pass (you'd have to hack the microcode of the DSD chip if that can even be done). That's just a guess since I could not find any relevant info on the net. I wonder if the RS232 port could be used...hmmmmm not that I'd take a crack at that myself. I'm definitely not a skilled hexx/code monkey.

Btw, the 3910 does a DSD-to-PCM conversion by default out of the box. There is a menu choice that changes it to Direct DSD, which sounds better. FYI
Unfortunately as jpelg rightly points out SACD/DSD is a locked protocol when it's comes to the digital outs (HDMI or SPDIF/TOSLink). The only way to get a pure DSD signal from these players is to use the proprietary iLink output which is only compatible with other Denon products (usually receivers of the same brand as the SACD player). I don't think HDMI 1.1 carries the SACD signal although it is activated (and still locked unless it sees a Denon enable product) via HDMI 1.3. It's a little confusing to say the least but somewhat straight forward.
I need to read up more on this so please don't take the HDMI info as correct as I'm not 100% sure about that.
At any rate it's good to know the 3910 has a menu toggle for DSD pure or DSD to PCM (available only through the 2.0/5.1 analog outs like DVD-A).
