Upsampling DACS: Take the Pepsi Challenge


HAs anyone used 2 of the following 3 relatively inexpensive upsampling DACs: Perpetual technologies, Bel Canto, MSB Link 3 with upsampling upgrade?? I am trying to sort out the details of the new technologies. The Perp Tech can "interpolate", while the others do not. I am under the impression that the "24 bit" part of this new technology has to do with s/n ratios aroung 140 db, which is great, but a little useless considering the other equipment in the system. The sampling freq is the part that has me all aflutter, because it seems to be getting closer to analog quality "infinite sampling" if you will... What do you think? Has anyone compared these dacs?? Thanks, gang.

It's interesting, the emotional truth at the core of music has nothing to do with the quality of the sound. Maybe that's why alot of musicians don't have audiophile quality systems. The music really is only in your head. Deaf people have composed symphonies and I bet they "hear" it better than most people.
OK, guys, read the thread topic, and please stick to it. ALso, BE NICE! Otherwise, I'm gonna put all of you in "time out"
All I did was try to stick to the thread topic, and yet it seems someone using a woman's name doesn't like that most audiophiles simply like "gadgets" and how things work, besides their love for music. I won't apologize for this, and I am even proud of it! It's in the nature of most men to be curious about the workings of the physical world (and it doesn't seem to be that way for most women). It helps them appreciate it better...whereas those who aren't curious about these "tidbits" very often seem to have little or no appreciation for them. (I.e., on interstate highways, women driving their SUV's...aren't thinking about how heavy an 18 wheeler is, so they very often drive in their large blindspots, only thinking about staying around the speed limit...rather than foreseeing the possibility that the trucker might suddenly need to change lanes. Don't tell me any of you haven't seen this a billion times, as well!) It's all a question of personal prioroties and observatonal logic/natural curiousity). And, I feel that my views on audio in general are representative of perhaps 80% of "audiophiles". Also, we don't listen to music because we don't love it...
WOW! Lets get back to the topic(s). I too am very curious about the latest developments in DAC technologies. Carl, maybe it would help us layman if you could explain upsampling using an analogy (like when math teachers use a pie to help students visualize the concept of division)... it might seem silly but it would help get us out of the abstract world and into the physical world where things are easier to understand. You would be doing us all a great service if you could find a way to clarify this once and for all. Anyway, I do have a friend coming over this weekend with the Bel Canto DAC1, so I might have some more to say about that product early next week.
I emailed MSB yesterday regarding the Link DAC III's ability to INTERPOLATE AND UPSAMPLE. The response was as follows:

Thomas, We do have this available, we call it our upsampling upgrade. It does smart interpolation and upsamples the signal to 24/96kHz as well as 24/132kHz.

This upgrade is $199.00 and can be installed by the customer at any time.

Thank you for your interest, Scott Rust MSB TECHNOLOGY This information lead me to order a Link DAC III with the upsampling and interpolation chip. When I asked the Scott why does MSB not state anything about Interpolation on their website, he said "Nobody Knows what Interpolation is". Anyway. I have Pioneer DV-414 as the transport and the Link DAC III will complement it. I just thought I would interject my ignorance or 2 cents which ever is worth more!
