But is it the femto clock that's responsible for that particular sound difference, or is it the whole package? ; )
As far as I can tell, no one has actually compared solely a femto to non-femto Geek device before, so the conclusion that the femto clock makes a big difference in sound isn't exactly accurate.
I knew the non firmware upgradeable display was going to bite LH in the butt. They should have done more extensive beta testing I guess with all the anger over delays they had to make a hard choice on who to please. On the other hand, I can't wait to receive my quiet naked geek
snip3r77 he's talking about the geek out which only has usb. but if you're talking about the pulse, only the usb uses the built in clock, coax and toslink use the clock from the source device.. I think.
Quite the opposite really.
For USB, the master clock is the DAC. (hence benefiting from femto in the Pulse)
For SPDIF, AES/EBU and TOSLINK, the master clock is the source. (hence it will not benefit much from femto in the Pulse, rather in the source)
Here is a relevant post by Larry:

This quote of Larry's is in reference to the Geek Source. I seem to recall it was determined elsewhere that the femto in the Pulse was used for all inputs. I'll try and dig up the original post.
Pure DAC vs DAC/Amp so what I can say is that They were similar in extracting detail. I had the Xfi unit so I had the Femto's in both. I did prefer my W4S but I attribute that somewhat to familiarity and that it did have the Vishay's in place already. It was more precise.
I am really interested to compare the infinity once it arrives!

Given the same DAC Chips, it was more about increased top end air and detail. I would relate that to the Vishay's in the W4S vs no Vishay's in the Xfi. Both were excellent. the W4S just went farther in that iteration.

Same family of DAC chips, but not exactly the same chip. Unless I'm mistaken, the W4S DAC2 uses a single ES9018S "Classic SABRE32" series chip whereas the Pulse X uses a pair of ES9018K2M "Mobile SABRE" series chips.

I owned the original DAC2 for quite awhile and it is an excellent performer. Looking forward to hearing what the Pulse X sounds like.
