I'm not sure I understand the extent of the modification.
I spoke toRichard Kern about a month ago,he was very detailed and
explained everything. The swapping out of identical parts in the audio board and power supply for another manufacturers parts seems
like a minimal approach.
Why would you not favor using the 777 as a transport and going digital out to a super high end DAC that has the optional ability to perform algorithms for 24/192 for your redbook CD playback. Isn't
that truly High Rez. Why would one wish to upgrade and still be
stuck with 16/44 playback?
Follow Ups:
So your saying the 5 cd filter selections Sony provides isn't enough; sure, go ahead and add another tone control device. RK parts upgrade and dac and 4 or 5 digital cables to play with...each one bringing something different out in my collection.... yeah sounds good to me.
Go ahead and upsample--going from 16/44.1 to 24/192 (not even a multiple of 16/44.1) will indeed create artifacts and add no new information, though you may be fooled by the illusion it does. I have not been impressed with audio "line doublers".Seriously, the advantage is to take Sony's stock parts out of the signal path and replace them with higher quality parts to hear what these babies can really do. It makes a big difference not just for CD but for SACD which no DAC will improve, of course.
as noted in my response to your other post on this subject. Note, too, that you're dealing with one less connection (i.e., to an external DAC) and two less cable sets (the digital cable to the DAC and the interconnects from the DAC to the preamp--you still need a direct connection from the player to the preamp for SACD playback).Actually makes a lot of cents.

OTOH, upsampling will introduce its own artificats, so it is not perfect but much better than 24/192. That is why I am interested in trying out AudioNote DAC 1.1. It uses gentler analog filtration, so no upsampling or filtration artifacts. Analog filtration is not perfect either, but its the best available today.

gsf,The primary reason would be cost. Richard's mod costs $400-500 while adding a DAC good enough to make a substantial improvement over the internal DAC would cost you $3000-6000+. Also the parts upgrade improves SACD performance as well as Redbook, while if you buy the Dodgson or whatever you hear the benefits only on CD. At least one inmate has noted that post modification he no longer felt his external DAC was superior and moved it to another system.

Agreed.

It doesn't sonically mean it puts the Audio DAC Kit 1.1 in the same peformance class with the Dodson DAC even the Sony 777 itself. Have you ever a/b'ed both?

According to many who compared, AN is waaay better.

No, but will soon enough.

I doubt if they compared the AN with the modified 777.
Adi, perhaps its worth for you to wait revision 1.2? Simon
