The photo above shows the UpTone Audio USB REGEN with the power cable the USB cable is not shown in photo. http://uptoneaudio.com/products/usb-regen   I'm using a Surface Pro 4 Intel Core m3 (fanless) tablet to stream Tidal tracks (Flac 1411 kbps - Lossless) (16/44.1 khz) into the UpTone Audio...

all999, your profile image, Beats By Dre. you should think about changing that just saying

Sorry it wasn't up to your review standards, Beats by Dre, but I'm not on clock here   http://www.digitalaudioreview.net/2016/04/audioquests-dragonfly-red-puts-high-end-daps-on-notice/   and   http://www.audioquest.com/wp-content/uploads/2014/04/Phase-Noise-Jitter-Report-0317-14.pdf

Nobody said HiFi was cheap, spending $200 dollars on HiFi doesn't get you very far these days. The AudioQuest DragonFly RED is one of those rare exceptions, I think it's the best value on the market today. The second best value in HiFi for under $200 is the UpTone Audio USB REGEN. Put these two...

Rolling the tubes to the Gold Lion GZ34 / U77 for rectification and a matching pair of 6DR7's was a reasonably priced roll that sounds nimble to my ears. I got the GZ34 from https://www.cryoset.com/ The 6DR7's are from Woo Audio stocks. I'm using HiFiMAN HE 400 planars, my source is the...

I don't think of myself as a Head-Fi enthusiast anymore. I have become kind of a head audio snob. Most of the head gear that I have reviewed so far has now become irksome with long term use. My DECWARE Zen Head amp now has touchy jacks in and out and the plastic slide off battery cover is fail...

I took another look at the stock Shuguang Electron Tube 274B and the Valve Art 274B rectifiers and now I'm thinking they are identical although the VA 274B seems a bit heavier. After a month of heavy use the Valve Art 274B now has a faint vibration/hum noise, I don't like that at all,   

  I got the 10% percent discount and free shipping November promotion. The Woo Audio WA6-SE needs no introduction, Woo Audio has the products and the path to the summit of head-fi on lock. This amp looks great and it kicks butt, like a Shaolin master from Wudang mountain. I'm throwing my Schiit...

  Volumes have all already be written about the pro's and con's of the Samsung Galaxy S5 smart phone so I'm going to skip right to my point. I've been mulling over the idea of purchasing a USB noise and power filter to go with my AudioQuest DragonFly for weeks. Instead I renewed my contract...

  ^ I'm streaming Tidal HiFi (lossless CD quality - FLAC-based 16-Bit/44.1 kHz) via line out dock to my portable headphone amp and cans, in this case the DECWARE Zen Head, Grado GS1000e    I've been using the iPad 2 as a source for years and it still rocks! The price is way down for a new...

http://www.audioquest.com/usb_digital_analog_converter/dragonfly-dac   "Fixed Output Feeds Preamp or Receiver" just knock that hard edge off this DAC with a good amp. The mids on DragonFly paired to the mids on the Valhalla2, matched with the mid-centric Grado = Lit-Up iridescent coloration =...

♫ But then I fooled around and fell in love, I fooled around and fell in love, yes I did . . . with the AudioQuest DragonFly

Your average Universal Serial Bus port was not designed to be a dedicated audio serial bus port. You can call it RFI/EMI, voltage ripple, packet errors, timing errors, noise, jitter, static, pops, clicks, glitches, dirty signal... whatever you want to call it and what whatever combination of...

I was also impressed straight out of the box with the DragonFly line out to amp, without the tube amp the SQ falls flat and fatiguing to my ears. The digititis is not my imagination or a faulty / funky unit, the problem is jitter. I've been mulling over the idea of adding a jitter reduction...
