    Schiit Happened: The Story of the World's Most Improbable Start-Up

    My idea of a perfect USB interface is that it would make all USB sources sound equally good, so USB on a Raspberry Pi will sound just like USB on a $5000 streamer. Well, nothing is perfect but my hope is that Unison moves the ball in that direction. This might imply that Unison is not of much...

    Schiit Happened: The Story of the World's Most Improbable Start-Up

    I might be interested in a well priced spinner if the new Unison USB cards have two inputs. The input on my Gen 5 card is taken. Even though the CD transport will probably have other connectivity options, USB is where they are differentiating this device so it would be a shame not to use it.

    Discussion on the Darko video suggests that Jason thinks it's good. Someday bits will be bits, as they should be.

    Dragonfly Black with Raspberry Pi

    I've had a lot of luck running my Dragonfly Black off my Mac. It sounds great. Yesterday I tried running it off the USB port on a Raspberry Pi v. 3 with Volumio loaded. In this configuration the music sounds more distant, almost like it is coming from down the hall (I'm using amp / speakers...

    Dynamic Range Compressor in VLC - WOW

    Someone tell me if I am wrong about this but I think that another effect of dynamic range compression is that there is a reduction of volume difference between loud, lead instruments and softer, background instruments within a given passage.  This can result in the loss of depth.  This might be...

    Rational reasons to love vinyl

      This is probably the best analogy I've seen to the vinyl thing.  I'll be quoting you on this - even though I know you're trolling.

    Rational reasons to love vinyl

    I've been listening to vinyl again for the last two months and I can say that the most rational reason for loving vinyl is that you like to play records.

    Rational reasons to love vinyl

    Is it possible that the analog stages of many CD players just aren't up to snuff?  I believe the science of why CDs should sound better yet I prefer the sound of my turntable rig (with its $100 cartridge and $100 phono preamp) to either my CD player or my USB powered DAC.  The DAC I can...

    HRT DSP / iDSP

    You're right. It's orange, brief, and not very bright. Seems to work though.

    I think it's the amps that will be gathering dust for a while.

    Reply to review by 'charlesc' on item 'Grado SR325is Headphones'

    I've been listening to new SR225e's for about 2 weeks.  I'm used to Senn HD598s so it's quite a bit different.  What I am finding is that I'm getting ear aches which is obviously a problem.  I've been using a couple of different small amps (Modi/Magni and microStreamer) but am now testing them...

    limits of usb powered DAC/Amps ???

    Thanks for both your posts.  I will probably have to read them each several times.

    limits of usb powered DAC/Amps ???

    Hi.  According to Wikipedia the max power that usb can provide a device is 5V, 0.9 amps.  Does this limitation only present an engineering challenge for DAC/Amp designers or is there a definite, line-in-the-sand practical limitation on the ability of a USB powered device to power hard-to-drive...

    Marantz CD5004, upgrade amp, dac, both

    Recently I have used both the cd5004 and Modi playing thru a Magni and HD598. My impression is that the marantz has a warmer, laid back sound. When I first started testing the Modi it seemed a little harsh compared to the marantz but as my ears and brain have adjusted I've begun to like the...

      Thanks. Nice comparison.  Very helpful.  Not sure what I'll do when the time comes.

    Sennheiser HD 598 Impressions Thread

    I've been assuming the HD650 would be my next (and last?) upgrade but the HE400i has become a distraction. I have no real complaint with the Sennheiser sound, I've just never heard anything else.

    Sennheiser HD 598 Impressions Thread

    Around here, HD598 owners are expected to think about upgrading to the HD600 or HD650 but is anyone else thinking about the HE-400i?  With the HD650 selling below $400 the Hifiman is more expensive but, on the other hand, it shouldn't require an amp upgrade.

    Lossless vs 128kbps mp3 vs 320kbps mp3 blind test

    If I said that I can tell the difference between 256k aac and alac what I would mean is that sometimes I can tell the difference. Doesn't a test like this require you to be able to tell the difference consistently to pass? It seems that even if you can only tell the difference 10% of the time...

    I can't hear difference between DAC anymore

    Lately I have been switching back and forth between a Modi (using ALAC files) and a Marantz CD5004 CD player.  What I think I'm hearing is that the Modi is more forward and detailed while the CD Player is smoother and more musical (probably not a great term for discussion purposes).  My...

    Headphones fast and slow

    Hi, I've been listening to my HD598s for about 9 months and like them a lot.  The thing is that I keep reading how they are slow but I don't know what that means.  Can someone please describe how the sound of a fast headphone would be any different than a slow one? Thanks

    The scientific merit of Pono

    The people that believe that will keep on buying iTunes and the doubters can buy Pono.   For me, while casually listening I believe I can tell the difference yet I do terribly on AB testing.  Sure, I may be delusional but it's also possible that once I've listened to the same piece of music 4...

    The scientific merit of Pono

    I think this is true.  Pono doesn't need to be better than CD quality, it just needs to convince some iTunes users that it might be better than 256k.  For my money, with disk space becoming so cheap it just doesn't make sense for me to purchase any music that is of lower quality than CD (which...

    I'm currently using CD Player plus Magni and it sounds very good.  Tomorrow night I'll be able to try MBP + Modi + Magni.

    Schiit Decrapifier released - USB power isolator

    Thanks for all the work you put into this. In case you aren't completely sick of this project, I would love to know your impressions of going from iDecice to Modi both with and without Wyrd. You da man!
