    Jaikoz Music Tagger 10.0

    I'm kind of lost with Jakoz tagger V10.0. Tried a few things for about 15 minutes, and here's what I found. For trial, I loaded an album that was tagged with MP3TAG using Discogs ID system. This works quite well, the actual version of the album as a code can be tied to their database. It's a little extra search to look up and ultimately over several albums reduces errors and also great for versions. When the same album is loaded into Jaikoz, the first entry is marked 0. Only software people start at zero, everyone else starts at 1, cause 0 is nothing. Electrically, 0 is a value and is important, but not music, omg. This album has 24 tracks, not 23 if you scan down the list..but the summary at the bottom of the page as 24, oh wait, Song No:23, so which is it? I have not seen an album track start at zero, ever. Don't confuse people. Also missing are the track numbers, so how to verify that the tracks are in order numerically and by description. The lookup album at Discogs doesn't work, just flashes the screen and nothing, perhaps a setup issue, dunno. The Uninstaller icon appears on the desktop, and clicking it opens Jaikoz, doesn't uninstall, bit of giggle. Bitdefender reported an intrusion into a Documents file of another application, a VISIO extension program of symbols. Keep your nose out of folders that are not of your own kind is the blunt message. Screen shot added. What's with all the 1's adjacent to the artist, Genre and others? No right click from File Manager? I'm not sure about 60,000+ tracks when it has trouble with 23, sorry, 24. Jaikoz doesn't grab my attention as a workable piece of software. Still lost.
  3. Independently used Musicscope to verify. Samples were LRA 2.8, Anniversary 5.8. Ask Roon how they work out their DR is the next step. Stored elsewhere is a 1987 copy local AU edition with sibilance as a bad bonus, "your housssseee deep in the desssert", just a mess. Wasn't until years later acquired a US origin CD and the sibilance was under control. The anniversary edition has "If it be your will", fantastic track with deep bass and piercing guitar, now that's a nice bonus.
  4. The Jennifer Warnes samples were downloaded and compared. The track is 'Bird on a Wire' from the 'Famous Blue Raincoat: The songs of Leonard Cohen' album. I play this album reasonably regularly and am very familiar with how it sounds, in fact, quite amazing. Downloaded sample files are rubbish. Roon reports DR 2 compared to the ripped local version of DR9 (I think it's the anniversary CD in the library). The dynamics are lost and all three, A, B and reference are horrible. The B version has a focused centre compared to A of the 10s I could stand listening. That's what I noticed right away, by the time the reference was played, there was something really wrong and couldn't listen any more. Played the ripped CD and that's more like the memory I have of the track, full of life, vocals front and centre and music spread from left to right, just classic. Have not answered the poll, the sources supplied are of insufficient quality to determine anything.

    Article: McIntosh RS200 Wireless Speaker System

    Not one photo shows the rear connections. It certainly looks quite a large device, pity it couldn't use height more instead of width, horizontal placement and table space is premium these days. For the amount of gear inside, the term compact is open to discussion.

    Mutec 3+ USB Midi Issues

    Chris would have mentioned that the USB front end current consumption on the USB input on MC-3+USB is a little on the high side? I can't remember now the exact number, but it is more than 200mA. A search here may reveal the exact amount. Even though the AC power is on, and you've tried USB3/2 and USB C each one has enough current capability, there's still a problem. A suggestion is to supply the 5V not from the computer, but from an independent power supply. Although the MC-3+USB has galvanic isolation, there's still some benefit to use a clean 5V from AQVOX (for example), where the supply is some 1000mA. The USB ports on the Mac are also shared with other devices internally, so each one robs a little more power every time. It's also possible that the USB port can be forced off due to energy saving schemes.
  7. For the Intel NICs there is a transmit buffer and a receive buffer and both maxed at 2048. If one buffer is 1024 try the same. At this stage where you're going to decide on a different OS, the same network card is fine. I have the JCAT card, it's a minor/small difference in resolution improvement but the main thing the JCAT allows a direct connection to the network streamer, and the network using Windows bridge, that's it, no need to go through multiple switches or routers, direct line of sight. Unless you have a three storey home to wire through. IMHO Windows Server does a good job of transferring audio data, for network streamer, you don't need any audio extensions, that's what crippled Windows 10 pro for me in a recent update, the SQ was unbearable.
  8. Well, that's what the man says " In almost all cases performance is improved only marginally when enabling network interface offload features on a PC. Offloading tasks from the CPU to the network adapter can help lower CPU usage on the PC at the expense of adapter throughput performance. " See also the other post on increasing the transmit and receive buffers.
  9. See also this post.
  10. Troll, I experienced stuttering on DSD256 files over the network, and thought about the network card to see if some settings would improve, it might be restricting data for reasons unknown. See this post for the optimisation of Network cards posted November 12. References are linked. Following the suggestions, the stuttering cleared and noticed, DSD file transfer speeds from one server to the other had improved. So far, here are the NICs that I've used the recipe with. Intel I210 Intel I217-LM Intel i210 Intel i350
  11. Did you try to disable all the offload functions in the network interface card? Made a huge improvement to my throughput of data.
  12. I wouldn’t mind to try optical to insert into the copper Ethernet line to the U1. The hesitation is trading what leaks through the copper versus the leaks added by the FMC, both of them. The cable to the U1 is about 35m from the Server which has a JCAT NET card. The sound is really, really engaging, so adding more bits should make it worse? Different matter if there’s a direct connection to the Lumin via fiber though. There’s no media to convert as this is accomplished in the SFP without the additional step.

    CD player and DAC compatibility

    If the CD player’s output is working and both DACs don’t play either, then the only issue is the cable. simplest and cheapest is the SE bnc output with any RG6 TV feeder cable with the adapter connector. 5m max length. The output should be is 44.1 so unless it’s 384 or something silly?

    So how does a $12.99 DAC sound?

    Update - sure as eggs if the power supply is changed, the muddiness is gone, only to be replaced by a top end that's too prominent. The PSU as an experiment was a 216 PP3 and 2 x AA batteries to achieve 12.4V. Worked fine for a while, about 45mins or so, then the terminal voltage dropped to 9V, so it was time to stop. Bass tightness improved quite a lot to a point where the blur between bass and drums is gone. Mids & vocals, can discriminate well, the top end though is too bright. There's that glare coming from something mixing with the output. Would a stronger PSU work to tame that treble, possibly. The ENOG2 is now a different animal, I may have found that DAC with the volume control after all. For the four different 'consumer' sources, the ENOG2 is a vast improvement over the Prozor, now to find a 2A + 12V linear power supply and tame that treble.

    So how does a $12.99 DAC sound?

    A month on under the bridge to compare a DAC that costs 13.8 times as much as the Prozor. Enter the Geshelli Labs ENOG2 with a plastic case, priced at USD179.99 (on special), totally made in the USA (FL). One of the very few DACs that support XLR as well as RCA outputs at this price range. Inputs are SPDIF Coax or Optical, the coax shoots to 192 PCM with no DSD capability or USB inputs. The supply includes a 12Vdc SMPS which contributes to the sound rather negatively. Tracks to evaluate the ENOG2 were Jennifer Warnes 'If it bee your Will' from the Inpex release of Famous Blue Raincoat, and Lydian Collective 'Loops' both Redbook. Jennifer Warnes has a very clear voice with a LOT of depth and control. The ENOG2 detuned the voice somewhat, almost adding jitter, well a certain roughness or veiled presentation, the guitar wasn't sharp as if tonally injected 3rd harmonic distortion. The instrument seemed 'far away' miked rather than close up. 'Loops' has distinctive drumwork, provided by the excellent Sophie Alloway, she goes to town in the middle of the track, using everything, the transients are super quick and praise to the recording to pick this up. Well, the ENOG2 doesn't quite understand Sophie's drums, and mixes the mids and bass like beer batter (all the one colour) the outcome is mush. The ENOG2 struggles with complex, high transient music. Could try a battery instead of the 12V SMPS, that muddiness is often a sign of a PSU that contributes negatively to the sound by adding garbage on the output lines. Alternatively a linear PSU with 500mA at 12V won't stretch the budget too far. Is it better than the $12.99 Prozor? Yes, but not for main listening sources, nowhere near an engaging experience. The output volume on the Prozor is now irritating being very low, I'm now on the lookout for a cheap DAC with adjustable line out presets.
