DACs and bass response?

Bass and power supply are linked in every way. This is because they share the same frequencies. The latest DACs are now using switched mode power supplies to great advantage at ultra high frequencies in order to get power supply noise far far away from the audible range.

Well, sort-of.  The real story is that the regulation on SMPS responds much faster than most LPS.  It has little to do with the 50 or 60Hz, more to do with the devices used, the "Q" of the storage capacitors and the technology used for regulation. 

LPS can also respond very fast, if the circuit is designed for it and the output device is really fast.  I provide such a fast LPS for my converter and reclocker products.  I also use SMPS in my Overdrive DAC.  They both can work for digital.

@shadorne: the reasons I haven't tried the benchmark are 1) complaints that it's a very complex component (not exactly plug in and play) and 2)  that it sounds thin/lean. You seem to be very technically competent, so let's set aside complaint #1 and focus on #2. I'll assume that you haven't found the sound to be wanting in this regard. Would you mind listing the source, amplification and speakers you're using in conjunction with the Benchmark? 

@audioengr,

Thank you for your feedback and sharing the link. I guess that’s one way to promote external reclocker by taking a subpar DAC/Streamer. I do not know about anyone else but IMO, SONOS connect box is a piece of crap. It’s also one of the most antiquated streamer/DAC in their lineup.

May be you can post some measurements with Bluesound Node 2 or Aurender N100 and Synchro-Mesh reclocker.  Also, what degree of improvement justifies the cost of external reclocker and digital cables?

Having said that, I do recognize the importance of a quality digital source and DAC that employs best designs attributes to minimize or eliminate jitter within digital domain.

I would be open to try an external reclocker between my two sources Aurender N10 / Bluesound Vault 2 and ARC DAC9 in near future. At this time, I am very content and happy with fabulous sound output of my digital setup.

The final jitter will be exactly the same, no matter what the source is. you can literally compete with a $20K transport using a $300 transport and a $1400 Synchro-Mesh and Dynamo power supply.  The input jitter to the Synchro-Mesh is totally unimportant. 

The Sonos is very popular and many folks like the interface well enough.  With the Synchro-Mesh reclocking, the Sonos actually sounds as good as any of my $3K digital interfaces, including USB and Ethernet.

I would be happy to if I had one of these on hand.  So far, everything I have compared with the Synchro-Mesh has much higher jitter.

When you are ready, I have 30-day money-back on most of my products, less shipping. BTW, I also now offer a truly world-class S/PDIF BNC/RCA cable for $499. My whole career in audio has been devoted to achieving the lowest jitter.

Steve,

“The final jitter will be exactly the same, no matter what the source is” - Agreed.

“You can literally compete with a $20K transport using a $300 transport and a $1400 Synchro-Mesh and Dynamo power supply”
- That’s a pretty bold statement, what have you tried and compared in that range to arrive at this conclusion.

“Input jitter to the Synchro-Mesh is totally unimportant” - Agreed.

“The Sonos is very popular and many folks like the interface well enough. With the Synchro-Mesh reclocking, the Sonos actually sounds as good as any of my $3K digital interfaces, including USB and Ethernet”
- Wyrd 4 Sound offers an somewhat similar internal upgrade for lot less. Once you add the cost of Connect, Mesh w/Dynamo PS, extra digital cable, you are already at $2250. It would be interesting to compare this setup with let’s say Aurender N100.

I wonder if anyone else from our esteemed community can chimed in with their experience with Mesh / Dynamo PS.
