Hmm, can you use the bluetooth adapter via motherboard usb port? If device shows up then it seems like a configuration issue. 

 

Solved. Bluetooth needed a reboot. :)

In January. There were no further changes from beta. There will be 2 scripts available: one for 2 active ports and one for a single active port which is what you have now.

Marcin

It's about time, Felipe. Can't wait to hear your impressions on the card itself and comparison to SOtM, after proper running in and delicious LPSU juice taken care of. Congratulations!

Hello guys. The USB card finally arrived here. I've already installed and started the burn-in process. I'm very impressed with the construction. In addition to the famous Crystek clock, I've seen that the USB connectors are Amphenol. All of the highest level! How can I get the new firmware?

 

The sound seems much better than the onboard USB connection and considerably superior to SOtM tx-USBexp, but I've heard just a few songs, and without proper burning there's no way to have a solo opinion.

Having the new firmware or not, you want to give the card enough burn-in time. Perhaps this is a good time to experiment various jumper configurations and power supply. Congrats and enjoy!

Hi FelipeRolim,

 

did you compare it with just the SOtM tx-USBexp or with the combo tx-USBexp + clock sCLK-48.0 with SOtM mBPS-d2s 9V battery PSU  ?

Hi thuanb. Yes, I'll respect the burn-in time, because it's important to extract as much as the USB card can deliver. Besides that, the warm-up time, at every system wake-up, is very important. About power supplies and jumper configurations, for now I'm using the own linear power supply that I built for my computer (internal MOLEX connector) and the filters in mode ON. For future, I'll try to change these filters and try another power supplies, especially external ones.

 

Hi FelipeRolim,

 

did you compare it with just the SOtM tx-USBexp or with the combo tx-USBexp + clock sCLK-48.0 with SOtM mBPS-d2s 9V battery PSU  ?

 

Hi DC. I haven't compared anything yet, but I don't have the clock and the battery. The clock is very expensive, and I didn't bought it because I was looking for a more "definitive" solution. This is why I bought the JCAT USB Card FEMTO. Regarding the battery, I know how it sounds, and I don't like it. For years I adopted batteries as a reference in my system, and among them, I met mBPS-d2s. Based on the linear power supplies I had at the time (all DIY), I noted that the batteries worked better with sustained notes of wind instruments (flute, violins, saxophones), nylon string guitars, soft feminine voices, while the linear power supplies always worked better on dynamic, high complexity and/or velocity sounds, such as drums, orchestras, guitars, steel string guitars, among others. Use a 20000mA power bank adapted to power the JCAT externally and you'll be able to see exactly what I've described. Li and NiCd batteries sounds practically the same, but ZiC's for aviation are much better and harder to beat. The SOtM battery has no differential. By removing the switching circuit between batteries, there's virtually no difference whatsoever. So, I started to study the sonorities of the batteries and the power supplies and try to optimize the linear ones, until finally I was able to build something that brought together the best of both things, and this is the supply that I currently use in my computer. The problem is that now this power supply I built is very difficult to overcome, so I'll need a lot of time to develop something external with 5v that has the ability to play better.

 

Yesterday I enjoyed a lot the system with the JCAT USB Card FEMTO. No doubt it has better detailing, much more precise sound stage and much more delicate sound. However, I still notice the typical sound of something without burn-in. I have the impression that there's a lack of articulation, of body and of dynamics. The sound is extremely clear, but there's still a little bit of wealth I had with SOtM, what makes "sound" sound like "music", hehehe. After 10 hours of playing, I thought it improved and these characteristics started to appear, but I didn't identify if it was the burn-in time taking effect, or if the ears got used to it. I need more time to define clearly.

Hi Felipe,

 

Thanks for the report!

The 'wealth' will appear once the burn-in is completed and, especially, once you load the new firmware ;)

 

If your DAC does not require 5V via USB ports, I'd recommend removing all jumpers from the card. 

 

Regards,

Marcin

Hi Marcin, unfortunately my version of the Ayre QB-9 needs the 5v via USB cable. I believe that only the QB-9 DSD is dispensing, because it identifies the signal via data path. Mine, which is the QB-9 192/24, needs the 5v signal to exit the standby mode. I've tried doing this with SOtM and it doesn't work, unfortunately. Anyway, I'll do the test later. Thank you! I'm waiting for the firmware!!!

As an alternative you can use a dual lead / separated usb cable (JCAT Reference for instance), and use a separate 5V power supply for your DAC. Then you can remove all jumpers and get even better SQ. So I've done, because even my DAC needs 5V.

Hello Tomslin. For now, I don't intend to change the USB cable. I'm using a Curious Cable and I like a lot its sound. Actually, I want to upgrade the DAC this year, so, I think that's a better choice, at least for this moment.

Many thanks for your comments FelipeRolim..

 

I asked you this because I'm using the SOtM combo on my audio PC with many satisfaction for about 4 years, now.

I've compared the mBPS-d2s with 9V PSU and I prefer the mBPS-d2s (more natural sound, better sound stage etc....). 9V PSU is not bad but I've found a little more brightness and sibillence with it than with the mBPS-d2s.

​It could be interesting to compare my actual SOtM combo to the JCAT USB FEMTO card.

I don't know many USB cards, just SOtM tx-USBexp (without sCLK-48.0), Paul Pang USB v2 and JCAT USB Card FEMTO. The worst, between these three, is the Paul Pang. I've already wrote about Paul Pang gadgets and I really don't like anything that he sells. It's a charlatanism. Regarding SOtM, I also don't know how much a dedicated clock could improve the sound, but, despite a few things that I hope that the burn-in and the new firmware solves (such as Marcin said), the JCAT is the best USB card that I've already hearded. The sound is in another level of detailing and fluidity, there's a lot of extra information in every music, the sound stage is incredible, but I miss a little of realism. I'm sure I need to give the card the right time so that it can work to its fullest, so any opinion is now premature.

 

About batteries vs. linear power supplies, the vast majority have the sound very close to what you described, so you heard correctly, in my opinion. This is exactly what I used as a reference in my linear power supply, so that after a lot of work I can make the sound go perfectly between aggressiveness and gentleness, speed and delicacy, hardness is subtlety. It was fantastic and, at this stage, the power cable is of fundamental importance. I currently have very good cables, Nordost Valhalla, Transparent PowerLink MM² and Purist 20th Anniversary. Only the Purist, among the three, collaborated so that the PC delivered all the best that a linear power supply and a battery can offer. I honestly think that we shouldn't disregard the importance of a power cable, even if it is to power a 5v power supply that will be connected to the USB card. Try it, you may be surprised.

 

I also think that everyone should compare, wherever possible, the batteries with linear power supplies. Differences in sound can greatly help define the "approach" we want.

 

PS: SOtM has literally abandoned its computer products and is dedicating itself to selling peripherals that, in my opinion, have little or nothing to do with true digital audio. Even a driver update they sent to tx-USBexp, which I've used since 2015 without an update. I sent them an e-mail questioning, and they told me they were satisfied. Since I wasn't, I changed the brand...
