A 40 Hz sine wave is about 28 feet long - 20 Hz is 56 feet and 80 Hz is 14 feet. This is why bass is considered to be "non directional."

It's fun to have people listen to one's system, then show a subwoofer behind the listening position. It sounds like the bass is coming from the man speakers.

At my place, on many songs, bass is very localized behind the speakers. It's a very eerie effect. This is both in my mancave and living room.

There are many examples. Here are two. I can "see" all instruments, including the drums, being projected in the volume of space between the back of my speakers and the front wall.

Mojo - Thanks for the link. Spotify has been downloaded to my laptop. I also ordered a Yamaha CDS-2100 CD/SACD player. The measurements at Australia's top stereo review site are off the chart good for both CD and SACD.

It's a $3500 unit that compares favorably to gear from Luxman and Esoteric, which are all over $10,000.

Included is a USB input to access the DAC from one's Laptop. Spotify will now be as good as any CD production.

My daughter is getting married on the 20th - after that, things will start getting serious. Looking forward to you getting yours as well.

Congrats on your daughter, Craig. I'm kind of worried now. I think you're telling us that sources become the ultimate limitation with the actives. We may need direct digital into the DSPs.

Those Esoteric units are beautiful. Another really beautiful rig set THE GRYPHON but stupid expensive as well.
They're so sleek while still massive and bold at the same time.

Think we are getting into the pride of ownership territory here ...
I doubt big heavy, beautifully built, optical media transports add much over cheaper versions ...

As the timing and accuracy are all in the electronics

Mojo is right ... the farther down the audio chain it stays digital the better off you are ...
at least in theory .. digital audio can be screwed up by bad digital processing and the final d/a convertion ... so the first component might be the best place to go analog ...

Even if the DSP had a digital port, what format would it support and how would that connection be made via a receiver?

Axiom could support direct digital with the Air platform but use cases would be limited.

On a different topic, Craig how many vortex ports are on the back of the actives? The passives have two.

Rich, jitter in optical discs is real and affects sonic quality. The jitter is found in playback equipment and also the production process. You can have a player with very low jitter due to stability of the servo and transport, but if the disc was produced with poor jitter, sound quality will be affected. And vice versa. The laser generator and optical pickup are also prone to various effects.
