  3) I finally dumped Jriver(the bits are bits Jplay-ban stuff was a "bit" much) and switched to HQPlayer. I love this player and it is soooo right for the micro. I am  upsampling dsd to 256(quad). It is nice to see the blue lite shine on the micro. I am still playing with settings and hope to find a way to play octo-speed.

 
Could you elaborate please on HQPlayer vs JRiver?
I'm using JRiver MC20 to convert on the fly ripped-from-CD-FLAC files to DSD (4xDSD is about the limit before stuttering starts, yet to fully try all the buffer/sampling options). And this sounds better than staying in PCM mode, despite the laptop's processer working increasingly harder as the DSD sample rate goes up.
 
In what ways can HQPlayer improve on this? Is it by inherently better SQ with any option, or does it allow more options?
 
JRiver on Windows doesn't seem to give options of converting to DXD, so haven't tried that yet (or even understand whether that's even possible).

Where Jriver is a multimedia player and mid-fi audio player that developed DSD capability as a later addition, HQPlayer was developed for this. It is high quality audio player with an impressive array of filters and upsampling algorithms that allow you to maximize your dacs capabilities. When paired with the micro idsd's advanced dsd capabilities, the possible setting combinations you can try are mind boggling. This player is a tweakers paradise. I have just begun to figure out a few settings and look forward to trying many different combos. What I have come up with plays quad dsd at a very high quality. I will continue to try more combos and see if it will successfully upsample to octo-speed. 
 
I have played pcm natively and upsampled with very good results. I will try this weekend converting my pcm to an upsampled dsd format. I will post results on that venture.
 
DXD is 352khz, 24 bit PCM. I think you can upsample to that in Jriver. My results of upsampling in Jriver were not so impressive and my on the fly conversion to dsd was not good at all.
 
Jriver's library capabilities are so much better, but it can not compete with HQplayer as a pure high quality HD audio player.

Got my micro this week and tried DSD for the first time i my life. I downloaded from Oppo's site, "Vision of Her" by David Elias in DSD64-2.8 Mhz format in pure DSD recording and could do an A/B comparison to the same song in WIMP HIFI (aka Tidal) in FLAC. Holy Moses! I just took a trip to Nirvana! DSD just killed flac! Flac sounds flat and dull in comparison at least with this song and of course the flac version could be a "bad" one but nevertheless...This was a real game changer for me and from now on, life will not be the same 

 How can I go back to flac?

Hi,
 
Just checked with the technical guys.
 
End of this week/early next week is when it will be available to all.
 
We try our utmost to test, test and re-test before things get released into the wild.

firmware for what, i am sorry am i missing out on some news here
 
is that a new product or a firmware update for idsd micro?

Hi,
 
David Elias (whom we know personally and is a super nice guy) made his recording at the Super Audio Center in Boulder, CO.
 
Hence when you listen on the nano/micro iDSD, you listen to a native DSD recording on native DSD playback. The PCM (flac file) came from DSD and as such has been transcoded before it arrives at your ears.
 
Now you know why we make a big song and dance (no pun intended) about keep the chain native all the way through,
 
PCM recording > PCM playback.
 
DSD recording > DSD playback.
This is grossly simplified but you get the gist of what we are striving to achieve.

 
 
Knowing what we know, we are actually format agnostic.
 
We love lager (PCM) and we love bitter (DSD). If it has alcohol (music) in it, just pour it down our necks.

This makes me want to buy everything you make and will make!

Thank you but you haven't seen our whisky collection in the AMR Showroom.
 
Now that would blow you away much more than our technology.
 
This is our current favourite:
 

 

This is the officier supplier to AMR/iFi. So we dont mind giving them a plug.

Kilkerran WIP 6th Sherry Bottling Note

The 6th release of the Kilkerran Work In Progress series follows the style set in the previous release of actually being two whiskies! Both are single malt Scotch whisky, though one has been matured in bourbon casks and one has been matured in Sherry casks. This is the latter, the seductive Sherry cask-matured Kilkerran single malt.
 
 
 
It is eminently reasonable at £36 a bottle. But the scary thing is this whisky is extremely smooth 'n seductive. Fifity Shades got nothing on the Kilkerran WIP.
 
We challenge anyone to have one "nip" and NOT want more. When the tunes are flowing this whisky is a gushing. We can neck one of these bottles in one listening session. Scary.

 

 

[bavinck]

You throwing in a bottle with orders for amps? hehe.
 
I think whiskey is a better analogy to your products than fine beer, and I love both way too much!! (beer and whiskey that is).
 
This month I am buying my X5, next month I hope to get your micro idsd.....maybe with a bottle of whiskey.........

I agree that HQPlayer has superior up-/re-sampling capabilities but the lame UI and lack of library functionality coupled with the relatively high price tag makes it a tweakers tool only.  Jussi really needs to improve this product to make it more user friendly IMHO.

  Today I played around with the filter settings of iDSD micro, monitored by simple USB oscilloscope (Velleman PCSU200). So line output of the micro iDSD goes direct to USB oscilloscope input (1 Mohm input impedance).
 
Line Output setting: Direct
Power Mode: Normal
Polarity: +
RCA Cable: Wireworld Luna 7 (50 cm)
Adapter: Monster RCA to BNC
 
 
Here are the screenshots if you guys interested, showing only the left channel:

This link does a nice job explaining in slightly more detail what we are seeing (hearing) with the different filter types.

Hi,
 
In principle, yes.
 
If there is no USB audio actually playing (but with a USB Cable attached) the iDSD micro will automatically select SPDIF and check if there is any signal, if so it will play this.
 
That said, some Linux based Computers ALWAYS play a signal (even if it is actually silence) so the iDSD micro never gets the "no music on USB" condition and cannot switch over. In this case the iDSD micro will also never go to sleep. There is no such issue on OSX and Windows.
 
So the more pertinent question is how the USB part works of the vendor of your player box.
 
Cheers.

 
Unfortunately I see this behavior (SPDIF is ignored when USB is connected but not selected) on OS X if I'm running BitPerfect or Audirvana+.

i was wondering since the firmware can be updated can there be a possibility of changing sound signature by changing doing changes in firmware
