  1. Now I got your message. It seems that it is a bit too early to go for large SSD's for USB use. I will rest my case to see what the future will hold.
  2. Thanks for comments, @rando I'm not looking for a "lower endurence memory". I'm looking for a reliable memory. I do not consider HDD as reliable. I thank the Lord that I have been very meticulous on making backups since I started ripping my music library (which took 3 years). If not, my files should be lost long time ago. I buy new HDD every 3-4 years to be on the safe side. I do not trust them. I use SSD for other purposes in the sizes 250 - 500 GB and they work great. The only SSD of 4TB I have found is the Samsung but it is only available as SATA. If there are other ones or better ones I'm open for this as long as they solve my need of space (4TB to cover my files) and sustainable quality plus that they must work with USB. You also say that USB interfaces is the least concern. I do not agree as this is the main issue I have read about including from the Swedish supplier who can't give any guarantees. I should appreciate if you could give a hint on how to solve it. If I read you right, you opinion is that Samsung 840 Pro is not a quality product. Please correct me if this wrong. Any other experiences and/or recommendations out there?
  3. I'm tired of HDDs that I replace every 4-5 years (just in case). I'm thinking of buying this Samsung 4TB SSD to be used as a mobile disc for my music library that today comprises about 3.2 TB. I use a quite fresh HP laptop as my server (win 10, SSD 250 GB, i5...) and only for music using JRiver. It works great. The question mark is how to use it with USB. I know there are interfaces like them from Plexgear and Delock (both with separat power supply). At the same time I hear sayings that they only work with smaller SSD's. Other considerations?
  4. I have friends on the continent that are very satisfied with Qubuz. Especially for their classical catalogue. In the Nordic countries (Sweden, Denmark, Norway, Finland) itbis not available for one or another reason.
  5. Recording companies like for example BIS make their recordings in pcm 24/96. They also sell those files for download. Discs are sold as SACD which means the files are converted to DSD64. This is also possible to do in many music servers like JRiver. Some can also do the conversion on the fly during Playback. Question 1: Generellay speaking are there reasons to beleive that it is better to convert the pcm file to dsd first and then play it versus do the conversion on the fly? Why? Question 2: Are there any differences between professional conversion eqipment/softwere (pcm -> dsd) and programs used by Roon, JRiver, Foobar etc? How? Question 3: More and more dac's convert all formats to dsd. Generally speaking, what are the big difference on their solutions versus use a pc/laptop/mac to do the same? Question 4: Conversion on the fly requires more CPU than playing "strait". In my case the graph shows average 10-12 % CPU versus 7-8 % without conversion on the fly from 16/44.1 to dsd64. In your opinion, how big processor is really needed? Celeron is known to very stable but can't match i5 and i7 in "power". 8GB or 16 GB?
  6. I started with JRiver v16 (as I recall). I have also tried Monkey and Foobar but stayed with JRiver, currently v. 24.0.55. The sound discussion between bit perfect media players is a "no question" for me. If there is a difference it is minor and nothing to make noise about in my view. When visiting friends using JRiver I see many times that they have set up Windows wrong. Some are not using the correct firmware, others convert DSD-files to PCM, some have not enabled Wasapi's Exlusive access or have older versions etc. My sound has improved a lot since I started with JRiver but the main reason for this are other things in my view. Some examples: I have bought a new laptop with more internal memory and faster processor I started with Win Vista and now run with Windows 10 Pro Windows 10 seems to have worked with their "audiophile" properties and can now handle 24/384 as default (if desired) I have also spent some time to set up Windows priorities in a more appropriate way using the advices from Brad Robinsons "Glitch Free" guidelines among others, which I found here on ComputerAudiophile. Another possibility is to install the Swiss Audiophile optimizer that is also used by SOtM. My laptop is dedicated for music only. For other use I need a separate laptop. The sound is far better today than before. There might be some changes in JRiver that contributed to this but I'm quite sure that the main reasons are to be found elsewhere like in the other changes I made. One good example is the stability, which was a big issue before including glitches. It is completely gone. The last 8-10 months (since I made the changes above), I had not a single dropout. JRiver is the same... It is very easy to "blame" everything on JRiver, Foobar2000, Audirvana or whatever is used. In my experince the real nirvana comes with a good supporting system like how Windows is set up, processors etc. To get sound from your laptop is not complicated but to take full advantage of it takes some workload and efforts. Some hardwares like SOtM is selling ready solutions including an optimized "pc" in a hifi look using programs like "Audiophile Optimizer" that sounds very good. Using a Windows laptop you have to do it yourself.
  7. Thanks for your comments. The latest update on this "glitches issue" is that I've been in contact with Jim White at Aesthetix. Jim says that they have mainly worked with Mac but for sure it should alsonwork in the PC world. They will make test using JRiver, Windows10 and see if the get the same issues. So for now the status is "wait and see".
  8. You have to look into the Romulus/Pandora Signature edition. Highest DSD rate is DSD128 and JRiver transfer it as DoP. True Native DSD Romulus and Pandora Signature offer true native DSD 1x and 2x functionality over USB and 1x DSD over SPDIF (AES/EBU, RCA Coax and TosLink). The entire DSP processing section is replaced (pictured above, click to enlarge). The new section includes an advanced Xilinx gate-array which allows the DSP to be completely bypassed for pure DSD 1x and 2x operation. No alteration of DSD data occurs. Many DACs in the market that claim to play DSD actually convert the data to PCM and thereby completely lose the purpose of DSD operation.
  9. I have no issues with pcm 16/44.1 -> 24/192 or DSD64. But on DSD128 I get small popping sounds or "clicks" every 10-20 seconds through the entire album. If I convert the file to DSD64 it is gone. Anyone who has any idea on where and how to find the source of this? I use a 4 years old PC 8GB laptop with AMD processor (only for music), Windows 10, JRiver MC24, Transparent USB cable to my Aesthetix Romulus Signature CD/DAC. Your pieces of advice are most welcome on how to proceed to find the source for this.
