Review : 10/28/2017


Hey Everybody,
Just wanted to share that I have in for review a product from Dignity Audio out of Hong Kong that is imported by TAS Audio located in Brooklyn NY. TAS Audio is owned/run by Allan who's a good guy and offers great products at very reasonable prices.
The product in for review is called the PPT-50 (power purifier transformer) which only can deliver around fifty watts, therefore you only use it with pre-amps, CD players, and DACS, not power amplifiers.  It weighs around 2 pounds and has a nice black case with the on switch on the front plate and on the back plate one outlet for the power cord to your piece and another for the power cord to the wall socket. 
I found more impact when I put it on the Micro-ZOTL, using Audio Archon power cords, then my CF-010 DAC. It added a touch of more air around individual players, a slightly larger sound-stage with more space between players, and added a smidgen of image density.  It did no harm, but added on these postive changes.  Not a sonic earthquake, but when I took it out I missed what it was doing and put it back in.
Now, the PPT-50 costs a whopping $150.00 plus shipping, with a two week trial period!  I have spent more on NOS tubes with less of a positive change.  I have a hunch, since my pre-amp and DAC are tube based the positive changes I heard might be even greater if your front end is solid state. Either way I'm keeping mine because of what I shared above.
As stated before the Elf's and DI's are conduits, so any changes upstream will be easily heard through them. Highly recommended!
