Hi Everyone, I recently delivery of the SOTM tX-USBultra and posted my impressions on another thread, but here it is again for those interested in this device. Initial impressions of SOTM tX-USBultra: I got delivery of my unit yesterday, then I plugged it in my system in the evening. What I did is to critically listen to 3 or tracks on my system with configuration (1): (1) Nimitra (JS-2)>>Curious 20cm link>>Intona>>Curious 20cm link>>RUR (LPS-1)>>Curious 20cm link>>Brooklyn DAC. The system simply sounded fabulous, music just flows with a sense of realism and 3D especially after installing my two dedicated circuits (one for digital and another for analogue) Here I would like to mention that I upgraded my AO from version 2.0 to 2.10 and it made a significant improvement, then I upgraded to the beta AO 2.20 and the sound went to another level (more transparent, wide soundstage and better separation). Then I removed the RUR+LPS-1 and replaced them with the SOTM tX-USBultra powered by the second rail of the JS-2 at 12V (my unit has the 12v option) so configuration (2) is as follows: (2) Nimitra (JS-2)>>Curious 20cm link>>Intona>>Curious 20cm link>>SOTM tX-USBultra(JS-2)>>Curious 20cm link>>Brooklyn DAC. just out of the box without any burn-in, configuration 2 clearly elevated the sound of my system in all directions, most importantly to me, a sense of feeling that the music is so real and so clear you feel that the notes are sharper and more defined in the soundstage, a veil taken off the music! (a cliche but it accurately describes my experience) I didn't try to power it with the VR MINI because I use it on the Brooklyn and if I change this configuration, then it won't be A/B comparison anymore. My logic now is that I can improve it by freeing the JS-2 from feeding two units and keep it only to Nimitra and get a dedicated PSU to power the SOTM tX-USBultra, but too early now to make any decisions before I get my DC ammeter working. So (RUR+LPS-1) will be staying with me for a short time to do some A/B comparisons after 1 or 2 weeks when the SOTM tX-USBultra has settled in my system and most probably will be listed for sale. My learning is that isolation by ultra-capacitors is important but super clock with a good LPS can be more important. I hope this helps others on a similar path
For sale is a SOtM "Trifecta" of SMS-200ultra Special Edition, tx-USBultra Special Edition and SPS-500 PSU. Included is a D-Link 5 port switch modified by SOtM with upgraded caps and components, which uses a clock output from the SMS-200ultra. These have taken my system to the best it's ever sounded. I am sadly selling to fund some unexpected non-audio related costs. These are about 1 year old - I am the original owner, purchased directly from authorized SOtM dealer Crux Audio. Condition is conservatively a 9/10 - they've been only installed in one place on my audio rack and never moved aside from one trip back to Korea for upgrades (see below), with a total of maybe at most 10 plug/unplug cycles. Rock solid reliability and stellar reviews throughout the web!

Asking $900. SPS-500 - upgraded eABS-200 EMI absorption material (+$20) - upgraded Evox capacitors (+$100) **Included with the SPS-500 is a 30cm 7N UPOCC copper Y DC power cable (+$300) Retail $500 + $420 upgrades = $900 Asking $650. Total = $3970 retail. Asking $2600 as a bundle, with individual prices as above. Shipping and Paypal fees (if any) are the buyer's responsibility. The upgrades a few months ago took the trifecta up another notch which I did not think possible. This brought up even more detail and realism in the sonic picture, with some improvements in midbass and soundstaging as well! All original packaging, boxes and accessories included. Serial numbers available on request to confirm with SOtM regarding update status, if desired. I'm located in Maine, with local pickup welcome!
