Still decent sound through my AKG K-271s or my Sennheiser HD-380s. It beats watching Flea Market Flip, Horders, or Walking Dead reruns which my wife is into these days. Chip and Joanna are pretty good at flipping houses. I know...a sad life.

jimtavegia, which "2 newer" Sonys do you use? Over the last few years I put together a small collection of Discmans but at the end of the day I listen to this little gem. Reading through this review I had a tinny background voice chanting "little did he know"(with nice Brit accent like from the movie "Stranger than Fiction"). Who could have imagined that in a few years even Linn and Naim start making CD players, but by that same time Sony gets into the race of making the cheapest Discmans. Portables like D-5, D-25, D-555 will be forgotten and outbid by digital shock protection and, eventually, by MP3.

Sony D-7S portable CD player

There's a race on between Sony and Matsushita, to determine who can build the smallest battery-operated CD player with the most features. Sony currently holds the lead with its second-generation D-7 ($300), about 30% smaller than the first "pocket" CD, the D-5. Most of the reduction is in height; both players have a horizontal cross-section only slightly larger than the CD itself. The illusion of smallness is further enhanced by an angled front panel with beveled edges.

Capital Audiofest Starts Friday

The three-day Capital Audiofest runs July 8–10 at the Hilton Hotel at Twinbrook Metro in Rockville, MD. With new, noon–8 pm opening-day hours designed to accommodate 9-5ers eager to top off their Friday with great sound, and completely renovated rooms that should offer even better acoustics than before, the at-capacity show promises 38 exhibit rooms (including 14 large rooms and one two-room suite), and a combined Marketplace/CanMania with 20 exhibitors total. Put that all together, and you end up with 103 exhibitors and brands combined.

Why Apple Acquiring Tidal Could Be Exactly What The World Needs

Apple is reportedly in exploratory talks to acquire Tidal. Though it's possible that nothing could come of this, and much of the online chatter surrounding this news is processed, regurgitated press release—I'd like to contribute to the speculation by sharing my thoughts: I think it's exactly what the world needs. It would be an intelligent move on Apple's part that would simultaneously benefit listeners, musicians—and of course, boost the high-end audio industry.

Primephonic's Hi-Rez Classical Downloads

Primephonic, a Netherlands-based site that prides itself on its superior classical music metadata, has launched in the United States. Currently devoted to hi-rez classical downloads in WAV (stereo), FLAC (stereo/surround), and DSD (stereo/surround), Primephonic also intends to launch the beta version of its high-quality streaming service later this year.

Kal,
I bought one of these with the power supply and upgraded USB card last year. It works as advertised and as you described. It sounds pretty good, although I have a CAPS server running a similar configuration of software that sounds just as good and cost half as much. However, you are right to point out that the hardware is woefully under-sized for such an expensive box. As long as all you want to do is run Roon Server under AO optimized Win 12 Server it works. If you start trying to add things like Room Correction, UpSampling, or other optimizers - it runs out of gas very quickly. HQPlayer - forget about it! Same for Dirac or Acourate Convolver. It just doesn't have the HP to do any sort of complex processing. It is probably best suited to the be the AudioPC in a dual PC setup using JPlayer and something with a lot more power to do all the heavy lifting prior to sending the audio stream to the SoTM for streaming to the DAC. I never tried it in this config because for me, it's too expensive to use that way. Other manufactuers have put out much cheaper devices for doing this type of light weight streaming.

Kal,
I found this article very interesting. I have two questions around the use of the tX-USBexp:

1. The exaSound e28 advertises “Time–smearing jitter, that killer of realistic temporal reproduction, has been pushed down to miraculously low levels via the ZeroJitter™ asynchronous USB interface.” Since you are using a DAC with an asynchronous USB interface, I am unclear as to the primary benefit of the tX-USBexp. Is the “ultra-low jitter clock” in the tX-USBexp even meaningful when hooked up to a DAC via asynchronous USB? Is the primary benefit the “special filter circuits” and “Ultra low-noise Voltage regulator” that the tX-USBexp also advertises?

2. In November 2015 you wrote an article on the UpTone Audio USB Regen. I know you weren’t able to test this with your exaSound e28, but I am wondering how the UpTone compares with the tX-USBexp. It sounds like they are performing similar functions, but the UpTone can be easily added to an existing server at roughly one third the price (roughly one tenth the price if you consider the sPS-1000 power supply as part of the equation).

Any insight would be much appreciated.

Kal,
Where/how do you get your multichannel FLAC files and other digital multichannel files? I really enjoy multichannel music, but my only real source is via SACD and Blu-Ray (the former I am not aware of how to rip to my computer, and the latter is almost entirely video concerts that I rip to MKV files). I have a large library of 2 channel FLAC files ripped from CD or downloaded from HDTracks and PonoMusic. I would really like to be able to have a digital multichannel music library that is similar to my 2 channel digital music library.
Thanks for the help!

Music in the Round #79

The SOtM sMS-1000SQ Windows Edition with AudiophileOptimizer and Roon: Not only does that very long name require finger-twisting shifts between upper and lower case, it really doesn't tell you what the sMS-1000SQ WE is.

Korean manufacturer SOtM, Inc. describes it on their website as a "music server based on Windows Server OS besides the original Linux [Vortexbox] OS based sMS-1000SQ." I'd describe it as a Windows-based PC that's designed and optimized to manage a database of music files and stream the music to local or networked DACs, and that supports multiple options for file management, playback, and target devices. (Hmmm: that's not much better, is it?)

Samson is indeed, a fantastic pianist. Track down his recording of Gaspard de la nuit - it is truly like no other.

I've had buying an LP12 on my mind all day. I'll have to get over to Overture in Ann Arbor to see one of these creations.

Nice post, Mr.Dudley!, this fella says he's made over a thousand of these plinths, hmm., I would've been selling them back in my Esoteric Audio Salon days ( 1985ish ), I did offer and sell all the various woods LINN offered back then ( maybe 5 different woods ) none were as nice as this man's work. I suppose I'll start looking for a nice Ittok/Asak as well.

Tony in Michigan

ps. My favorite arm was the Sumiko MMT, I had a large collection of Koetsu as well, all mounted on head shells, ready to play ( and sell ). I miss those days. I wonder if Woodsong would make a Record Mat? ( two sided, different woods on each side )

... for another very well-crafted article on something other than "downloads for the masses".

Box Furniture, Woodsong, ... wonderful.

I have an early VPI Classic, with the somewhat clumsy veneer on the angled corners. I have fantasized for a few years that Woodsong will make a new Classic base that looks as good as the rest of the turntable.
