The DigiBUSS is going through a small change right now.  Nothing huge or mind blowing, just a production change to accommodate component availability.  It does not effect SQ, just allows me some attitude in component sourcing.  The difference is +/_ 5Hz in the LF turnover frequency.  I can't hear the difference, I'm just trying to allow for components being 12 weeks out.

Parts sourcing is one of the hardest things a small manufacturer like me needs to contend with in providing the best gear that I can.  I try to stay on top of availability issues.  I'm just glad I caught this one.

The Digi continues to amaze me and my customers.  RFI is running rampant in our systems these days.  I is more than curious that the elimination of it cleans up a system so much.  My greatest accolades are coming from people that have analog front ends.  Seems that the elimination of RFI in the head amp is extremely important.  Makes perfect sense tome.

I hope that those of you that have the Digis will post your results and also suggestions for making it better.  Same goes for all of my products.

At this point all I can say is: Go Denver!!!  I just want to see Peyton get that which has always eluded him...  He truly deserves it.

A few words on my experiences using the DigiBUSS.

I have the DigiBUSS circuit built into a customised MiniBUSS with a defeat switch, making comparisons very easy.

After giving the MiniBUSS several weeks burn-in period with the DigiBUSS circuit engaged, I disengaged it. Suddenly there was an added tizz, a flattening of the sound-stage and image depth, and an added quality to the music that made it seem less natural. All this was quite obvious, though not dramatic, never the less detracted from the listening enjoyment quite significantly, and I soon had to switch the circuit back in to resume my listening pleasure. I found what I heard quite surprising, as I was expecting something much more subtle, and all this after the MiniBUSS and two of the excellent LessLoss Firewall Modules, which together made a substantial improvement!

So, for the price of an inexpensive tweak, Dave offers a very worthwhile addition.

   Could not agree more. If one owns a digital anything the Digibuss is a no brainer. TV and cable box as well just stunning color.
    It is like buying a new DAC or CDP IMHO. Selling like hotcakes

Have my DigiBUSS on order from Dave. 

Should be very interesting with the MS-3 Music Server and dspMusik digital crossover.

Having very nice success with my DigiBuss now between Uber and digital components.  I swear I could benefit having a couple more elsewhere in the house where things are generating lots of badness.

But, Dave, I gotta say... 'Go Panthers!'.  It's not often we North Carolinians get football bragging rights.   Should be an interesting game.

Thank you for your observations on what the DigiBUSS concept does when used in your system.  I'm very pleased that you are pleased and appreciate the review.

Your use of the word "tizz" is one of the best terms I have heard in conjunction with digital noise.  That sense of graininess is a white noise component in the extreme highs.  It not only pollutes the power supply rails and ground plane in equipment, but uses more power than one would think in reproducing it.  It is hard on tweeters, too.

A little more info about Mr. Massarano's special unit. We talked for some time about what to build for his 250VAC application.  Ended up with a hybrid of a DigiMini(MiniDigi?)BUSS using Schuko receptacles.  We settled on the GigaWatt Schukos and I have to say that they are exceptional in build and sound quality.  Well worth the wait.  For any of you Nervous Guys that live where Schukos are the norm I highly recommend them.

Mike, Charlie.  SB 50 will be very interesting.  Cam and that offense vs the Big D of Denver.  I just hope it is a good game.

Could be brutal...

Remember that the DB was designed to quell the SMPS digital nasties.

If you can, get all of the wall warts together in one location on the opposing branch circuit to your system. You will still get noise on the neutral, but you will have 'some' attenuation on the hot.

You are right about additional noise suppression for D-nasties, no matter what you use.

Noise just sucks.

Newbie here.  My DigiBuss should arrive next week. It will be installed between my UberBuss and my digital front end. Also have full loom of TWL PCs in the system.  I'll report back with impressions.

Thanks to rollo for breaking it in for me while I'm away on vacation :thumb:

  Hey Don welcome aboard. Break in takes a bit longer than anticipated. Still changing after 150 hours my customers are reporting back.
   The Uber Buss took a little over 400 hours to stop changing and when it did OOOh la la.
