  1. The USB-TXultra does not have a similar cap, the power goes straight from the power input board to the clock board. Since SOTM doesn't make a "Neo" version of the USB-TXultra, so it's going to be hard to replicate one.
  2. The filter cap in the power input board is only applicable on the SMS-200 and SMS-200 Ultra. That cap is the only difference between the later Neo models and the originals.
  3. The factory cap is 25mm tall, and that Mundorf appears to be 50mm tall and 35mm wide (https://www.mundorf.com/audio/en/shop/capacitors/power_caps/mlytic_ag/MLytic-AG/?card=2481), so I don't think it will fit even if you extend the leads and put it sideways.
  4. The Nichicon KA series cap you used is an excellent general use audio cap, but the Nichicon KG series cap that I listed in my original post is Nichicon's highest grade cap for this application. The KG costs twice as much, but it's a direct fit on the board, and it's specifically made for high end audio power supplies. Parts Connexion is great for boutique parts, but they only carry a small percentage of Nichicon's product catalog. Digikey and Mouser offer significantly more choices, faster shipping, and better prices. Anyone can order from Digikey and Mouser, and there's no minimum order.
  5. I'm offering my SOTM sPS-500 power supply for sale. I bought this unit new from Canadian Authorized Dealer in August 2017 to use with my sMS-200ultra and tX-USBultra (both of which are sold). This power supply is extremely versatile as it can be set for 7Vdc, 9Vdc, 12Vdc, or 19Vdc output voltage, and it can provide enough power for just about any digital device (50 watts). This model currently retails for $500 USD, I'm asking $385 USD. The unit works perfectly and will come with all original boxes, accessories, and documents. Buyer to cover shipping costs from Calgary, AB, Canada (T3H 0R6).
  6. I’m offering my fully upgraded Singxer SU-1 USB digital bridge for sale. This unit is in excellent physical condition, and has the latest firmware installed to support DSD512 playback via i2S. I will include the original USB provided by Singxer (which is decent) as well as a generic IEC cable. Most members of this site are probably familiar with the lengthy thread that discussed various parts substitutions and upgrades which can significantly improve the performance of this otherwise excellent unit. I ended buying two SU-1's to experiment on so I could compare different parts combinations and determine what sounded best. This unit has my final “recipe” and it has been an essential part of my playback system for several years. I spent approximately $125 USD on parts upgrades which include Belleson and Dexa precision voltage regulators and various Panasonic, Nichicon, Wima, and Vishay capacitors. I’m only offering this for sale as I bought an SU-6 at much greater cost. I’m asking $350 USD / $480 CAD + shipping from Calgary, Alberta, Canada (T3H 1L5). I have extensive feedback on US / Canuck Audio Mart, Audiogon, eBay etc.
  7. I’m selling my SOTM TX-USBultra Signal Regenerator / Re-clocker. I was surprized to discover that this device significantly improved the sound of my system which was based on the superb SMS-200ultra network-endpoint / streamer. This unit has the optional 50-ohm external clock input (a $100 option), is in mint condition, works flawlessly, and will ship with all the original packaging and accessories as shown in the photos. These units can be configured internally to function on a variety of DC voltages. This unit came from the factory set to operate on 9V DC, which is also what the original wall wart power supply provides. Currently this unit is set to function at 12V DC, which some users have found to improve sonics. If the Buyer plans to use a high-quality 3rd party power supply, I suggest leaving this unit at 12V. I can change this unit back to 9V operation on request; it requires some soldering expertise so some users may not be comfortable doing it themselves. I’m asking $650 USD / $900 CAD + shipping from Calgary, Alberta, Canada (T3E 1L5). I have extensive feedback on US / Canuck Audio Mart, Audiogon, eBay etc. See my other ad for the matching SMS-200ultra Network Endpoint / Streamer.
  8. I’m selling my SOTM sMS-200ultra Network Endpoint / Streamer. I bought this brand new from an authorized Canadian dealer in August 2017. This unit pre-dated the “Neo” version, but I have since installed the Neo / Evox capacitor myself. This unit is in mint condition, works flawlessly, and will ship with all the original packaging and accessories as shown in the photos. These units can be configured internally to function on a variety of DC voltages. This unit came from the factory set to operate on 9V DC, which is also what the original wall wart power supply provides. Currently this unit is set to function at 12V DC, which some users have found to improve sonics. If the Buyer plans to use a high-quality 3rd party power supply, I suggest leaving this unit at 12V, but I can change it back to 9V on request. More information on the cap upgrade and voltage settings can be found on the thread I started here: https://audiophilestyle.com/forums/topic/57483-sotm-sms-200-neo-upgrade-diy-capacitor-details/?tab=comments#comment-1023710 I’m asking $800 USD / $110 CAD + shipping from Calgary, Alberta, Canada (T3H 1L5). I have extensive feedback on US / Canuck Audio Mart, Audiogon, eBay etc. See my other ad for the matching SOTM TX-USBultra USB digital audio regenerator / re-clocker.
  9. Sorry for the late reply. If you're handy then I'd go with the Kemet, but the Nichicon is a much cleaner fit. That's a good question about which electrical qualities matter most. The Kemet is rated to handle very high ripple, but unless you're powering your SMS-200 with a super crappy power supply, that isn't likely to be needed. The original Elan Tonerex is an "audio grade" cap (a notion of which makes some electrical engineers cringe); generally audio caps have poorer overall specs than other series, and they usually physically larger. The Kemet is the biggest, so maybe that's what matters most! As for upgrading to a regular SMS-200 to Ultra, adding a tx-USBultra after your SMS-200 should get you the same results. That said, I was surprised to discover that adding the tx-USBultra after my SMS-200ultra resulted in a significant improvement in my system.
  10. The internal change is only required on Ultra models, as it pertains to the sCLK-10Ex clock board. I'm attaching a picture that was provided previously by SOTM which shows the positions on the board you need to look for, along with pictures of my own boards (my SMS-200 ultra has rev 1.3 and my tx-USB ultra has rev 1.2). For rev 1.3 boards, you just need to remove one or two jumpers. For version 1.2 it's necessary to remove a blob of solder that connects two solder tabs on the board labelled as R342. I highlighted jumpers with red circles, and the solder points with blue.
  11. I bought the original sMS-200, and then upgraded to the Ultra as soon as it came out. When the Neo version was released I couldn't bring myself to buy yet another new model device, nor was I keen on shipping my unit away for an extended period to have the Neo upgrade performed. Initially, the details of Neo hardware changes were scarce, but later it became known that it was a capacitor change on the power supply input board. It took some time, but I was able to find the specifics of the Neo capacitor, and I also researched couple of other alternatives which may be easier to obtain, and quite possibly be better capacitors. I'm posting this here in case other owners are interested in the upgrade for themselves. It should go without saying, but opening your own SOTM device will probably void the warranty, and if you don't have a reasonable amount of experience with a soldering iron, you could easily damage your device. To cut to the chase: the Neo devices use a 3300uf 25v cap in place of the 2200uf 25v cap that is in the original models. Below are the complete details of the original caps along with some alternatives. A) Elna Tonerex 2200uf 25v – The original non-Neo Cap This is a high-quality capacitor from a respected Japanese manufacturer, and it has less capacitance than what is used in the Neo. I was unable to locate the datasheet for this particular capacitor, but Elna markets Tonerex branded caps for audio applications. B) Nichicon Gold Tune KG 3300uf 25v – A good alternative cap choice for someone who wants to upgrade their SMS-200 to Neo electrical spec. https://www.mouser.ca/ProductDetail/647-LKG1E332MESZAK This is high quality audio grade cap from a premiere Japanese cap manufacturer that is the correct value for the Neo upgrade. The nice thing about this cap is that it is a direct fit for the SMS-200 board (“snap-in” solder leads with 10mm spacing). The datasheet for this cap indicates it was designed for high quality audio power supply applications. C) Samyoung KMG 3300uf 25v – The cap SOTM uses in Neo products SOTM uses this cap if you pay SOTM for the $30 Neo upgrade. I don’t know how to source this cap aside from SOTM Dealers. Samyoung is a Korean capacitor manufacturer whose products are used throughout the SMS-200 and other SOTM products. The main downside to this cap is that it’s lead spacing is tighter than the original Elna, so it won’t sit flat on the board; hot glue or silicon can be used to secure it in place before soldering. The datasheet for this cap indicates that it's a general use cap, so no fancy pedigree here. D) Kemet PEG226 3300uf 25v – An alternative choice that could be similar or the same as the SOTM “Evox Upgrade” https://www.mouser.ca/ProductDetail/80-PEG226HJ4330QE1 This is a very high-quality capacitor which was previously sold under the Evox Riva brand (Kemet bought the company). SOTM offers an upgrade for $100 USD that is referred to as the "Evox" capacitor upgrade. I have observed that SOTM has used Evox PEG224 series capacitors for power supply filtering in some of their other products, so it stands to reason that they are using something similar in the Neo Evox upgrade, however this is speculation on my part. The PEG226 is basically a super duty capacitor designed for high ripple current applications and harsh physical environments. This cap is an axial form factor instead of radial, so some minor contortions are required to install it. Due to the bare exterior of the body, I recommend covering both the leads and the body with heat-shink to ensure it cannot short out against any nearby components. I went with option D, as shown above. I secured the cap in place with 3M thermal adhesive. I also used this opportunity to covert my device to 12V operation. While it wasn't night and day, I do think my player is sounding better in it's new configuration.
