Twister6 posted a review of the Vega single dynamic driver (DD) IEM over on Head-Fi. Not surprising, the bass is great. Delivering bass with small number of balanced armature (BA) drivers appears to be a challenge which is likely why we have seen the rise of DD/BA IEMs over the past couple of years. The DD delivers the bass and lower mids while the BA drivers take care of the mids on up. Twister6 has comparisons of the Vega with various other IEMs. A very nice review.
Unfortunately, the Vega retail for $1,299 with used going for around $700-800. These price ranges open up a number of other IEM solutions.
Pros: BASS, resolving detailed organic sound, unique shell material, premium ALO cable, leather case, accessories.
Cons: the sound is eartip depended, the bass quality could be source dependent.

Twister6 posted a review of the $1,000 dual DAC DX200 digital audio player over on Head-Fi.
Pros: neutral revealing signature, dual ES9028Pro DACs, DSD512 support, Android 6.0/WiFi/Bluetooth, 2GB of RAM, leather case
Cons: single microSD and 64GB of internal storage, battery life due to high power AMP module, firmware is almost there.

Currawong has posted a review of the Utopia on Head-Fi. As with comments from other reviews of the Utopia, you must have a TOTL ecosystem to support these headphones. Poorly mastered recordings or average amping will make the Utopia miss its mark as a true top-end headphone i.e. Stax SR009. What this means is that you will need $4,000 for the Utopia plus a chunk more change on your amp/DAC/cables/power purifier/turntable/Hi-Res (and well mastered) media. My ears are no longer capable of supporting this sort of expenditure.
The review includes comparisons with the Sony MDR-Z1R, HD-800, MrSpeakers’ Ether Flow and the HiFiMan HE1000 V2.
Pros: Incredibly resolving of music and upstream components. Incredible driver speed and ability to perceive width, depth and the movements of sounds.
Cons: Incredibly resolving of music and upstream components. Sound a bit closed-in if not used with a top system. Bass a bit weak and has phase issues.

EZE99 posted a review of Noble’s Dulce Bass IEM over on Head-Fi. This is the replacement for the original 5 BA driver. Included in the review are comparisons with the Dunu DK-3001 and Earsonics SM64 IEMs.
Pros: Amazing Bass, clear audio quality.
Cons: Fit, Slight compromising of treble and mids
Review of the Dulce Bass
Zelda provided us with a review with the dual BA driver $199 IEM from Brainwavz. From the review the B200 is a better IEM than the single BA B150 but Zelda believes the B150 is a better value as it is half the price. Personally, I would look into the 1MORE, Easy LZ or even the Echobox Finder IEMs.
Review of the B200
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.

HIGHRESAUDIO TO STOP OFFERING MQA
HiFiChris posted a review on Head-Fi of the Mini2 IEMs. Priced at around $100 for the dual balanced armature drive IEM these gems are really small. They might be ideal for folks with narrow ear canals as the Mini2 only has small silicone tubes which insert into your canals ( with tips of course). Take a look at the review by clicking the link below.
Pros: detailed, coherent, tonally well-balanced, precise, inexpensive for what it is and delivers
Cons: nozzles are basically flexible silicone tubes
