Beware of MQA!

A press release from Highresaudio announced that they are stopping their streaming of MQA encoded music due to the fact that MQA inherently does not reproduce the original signal and therefore isn’t lossless.  Further, the folks behind MQA state that their solution retains only those aspects of the ultrasonic signal that were significant to audible sound quality. So by default the resulting MQA encoded music will not match the original.  Others in the music industry have voiced similar complaints.  Further, it is unclear to me on whether you can apply any quality control to the data stream being sent.  I am holding to my original position that MQA is an approach to attempt to coerce hardware, software and streaming vendors to license this new proprietary solution rather than using the existing open standards.

Schiit Audio Jotunheim Headphone Amp/PreAmp Review

Chris Martens posted a great review of the outstanding and innovative Jotunheim Amp/PreAmp over on Hi-Fi+.  BTW, there are optional DAC and phono modules.  The Jotunheim provides single-ended, balanced and RCA outputs.  It is all around an outstanding solid state machine.

Chris Martens has a review of the X1 IEM over on  It’s a nice IEM, very light and compact with a pleasant sound signature.  I purchased one as part of Echobox’s Kickstarter campaign for ~$79.  If memory serves me.  The current listed price is $199 which I think is a challenge since there are so many great hybrids in the sub-$150 range.

Schiit Audio Yggdrasil DAC and Ragnarok Amp Review

Chris Martens has a review on Hi-Fi+ of the outstanding Schiit Yggdrasil and Ragnorok DAC/Amp stack.  This is the high end of the Schiit line and they are outstanding.  I have spent several hours over the past year listening to them at various meets.  They aren’t cheap and the aren’t gimmicky.  They are simply excellent products and a good price.  One of the best price performing stack on the market.  Someday and might be able to purchase these but for now I revel in my Bitfrost/Valhalla stack.
