APL 3910 owners, has anyone tried APL upsampler?

Hi,
I spoke to Alex today. He told me only a couple of people have even listened to it. I got the impression no one has yet to receive it. I will be sending mine in to have the upgrade. i can tell you if Alex says it is better yet for redbook, you can take it to the bank. The only hesitance I had was how could it be better? Once again, if Alex says there is improvement, I believe it. He has always been very honest with me.

Thanks Tom, it's probably too early to expect any feedback yet.

After reading so many positive posts on Audiogon and AA I just can't wait to get my APL-3910. The only decent player I heard in my system was Audio Aero Capitole II and it was very, very good but I think APL 3910 should sound better.

Kaaos, Your right, you will be AMAZED at the improvement over the AA. I am shipping mine back to Alex next week, uuggghhh, I hate to part with it, but I will let you know after I get it back. I have found out over time, I just do what Alex suggests, as far as digital goes. Now, if the guy just got his amps, and speakers going, maybe I could stop searching....remember, the APL really comes into it's own after 500 uugghhh hours.

I thought i remembered reading comments from Alex saying something to the effect that "upsampling does nothing" and is "strictly marketing", etc... Am i confusing him with someone else??? Sean

Based on a search of the archives, Alex is not a fan of non-linear conversion, often refered to as 'upsampling' ie 44.1 khz to 96 khz etc. Referring to APLs website comments he is technically ony performing linear coversion, often referred to as 'oversampling' ie 44.1 to 88.2 etc. The difference between the two methods is that non linear conversion in a binary based system like digital must by definition involve truncation of bits at some point in the conversion. Linear conversion does not involve any truncation of the original signal.

This makes sense to my brain and confirms what my ears have known for much longer. I have never liked any implementation of non-linear conversion. Players and digital remasters that upsample the redbook standard to 24/96 have rarely sounded right to my ears.

In general terms Alex's oversampling implementation doubles the sampling rate and the takes the bit rate to 24 bits.

Hope that helps
