Super Best Audio Friends

These are ortho iems with a different form factor and slightly lower price than the Timeless. And a different tuning. This will be a brief introduction to their sound to be followed up by better impressions by all of you on the loaner tour



They are just as resolving as the Timeless, but I can see how people would say they are more resolving. They have sharper transients, but I don't think they are actually more resolving of information.

They are also tuned higher, with less bass and more treble for a much brighter, airer sound. I find them too bright for me unfortunately, but I think with tight sealing tips some will like this presentation. It woks well for acoustic, jazzz and classical. They seem kind of like the HD800 of iems to me. They are in fact quite resolving. When there are no cymbals to be splashy in classical or instrumental music, I really like them, they sound spacious and airy for an iem. I could actually see people listening to classical music on these and really enjoying it due to the extra presence in the air region and spacious soundstage. Bass is tighter than the Timeless with more texture and definition but there is also less bass than I would like, and less quantity than the Timeless by quite a bit.

The original Schiit Mani was put through its paces on changstar back in 2015. No, it didn't win the shootout. However, it held its own against much better competition, only to lose against the Franken TC-750 (partially DIY). Looking back, perhaps I've been unfair to the original Mani. No doubt it was a high value. However, it just wasn't good enough for me. That is good enough to work as a secondary phono pre on my VPI Classic 4 table which supports multiple armwands. I know, it isn't quite fair to expect a $150 to do justice to a $10k table. It isn't quite fair to expect a $150 phonostage to keep up with a cheap commercial unit modified with boutique caps and a beefy LPS. However, I can DIY and I'm a cheap bastard. I have high expectations even for $150 gear. To be fair, the original Schiit Mani has provided many vinyl noobs (and returnees) with hours of listening pleasure at a bargain price and with better performance than more expensive entry phonostages from already well established names.



No doubt, the Mani 2 would be better. What I didn't count on is that it's a helluva lot better. I can name two phonostages priced about $1k which I own or owned which the Mani 2 easily bests. A big reason for the improvement is this: DC coupled, that is no coupling caps in the signal path (excluding the RIAA network caps of course).

ETA, the project started by @E_Schaaf and @tommytakis, have come out with their next headphone. For those of you not in the loop, ETA is aiming to produce high quality, affordable dynamic-driver headphones through 3D printing that compete with the more traditional big-name dynamic driver companies. Their first headphone, GenG, debuted here not long ago to generally positive reception, though there were some criticisms of the tuning, soundstage, imaging, and overall build quality.



The Mini is ETA's latest headphone. This is a bit of an odd one, as it was originally planned to be a limited release that simply used the rest of the GenG drivers. However, after some fiddling with it, Ev decided that it would make sense as the "entry-level" ETA headphone because of both difficulties in producing the other model they were working on, called the "Supra", and a break-through in the design of the Mini.

I wanted to get my hands on the Diablo because of a singular use case: a transportable AIO for full-sized headphones, specifically the ZMF Verite Closed (and to a lesser extent the HD6xx). I'm sure people will have other use cases which they want explored. I will do my best to cover them if asked; however I won't make my usual extended efforts because I lack time these days.This unit will be going on loaner, so sign up if there something about the Diablo that you want to evaluate that I did not cover sufficiently.



The measurements will come later. I feel doing subjective testing under controlled conditions and an extended period of time first is better than measurements first. Doing measurements first can result in confirmation bias and cause me to do dumb things like crank up the volume with the HD650 at 105db and proclaim that I hear -88db THD+N distortion from the amp, when in fact I'm hearing the -23db THD+N distortion from the headphone.

No more speculation. I feel I shouldn't really say much because I'm modding Audeze headphones. But I will say a few positive things.



Best stock Audeze I've heard as far as clarity and resolution
No midrange recession
More open sounding than previous Audeze's

The Humminguru (HG for the rest of the review) is a fully automatic, one step process ultrasonic record cleaner. The HG originally started as a Kickstarter campaign in Dec 2020. Shortly after fulfilling campaign backers fall of 2021, I bought one of the first retail versions in Nov 2021. The HG is produced by Happy Well Tech (a subsidiary of Happy Well International Enterprise LTD) out of Hong Kong. They also own and operate the factory the HG is produced in, located in Zhuhai China.



I’ve cleaned just over 300 records now with the HG’s and have just a little over 150 to go. It’s dead simple to use and the fact I can set records in and do other things is important to me. I just couldn’t get on with manual cleaning. It demanded too much attention from me. Can’t drink fabulous Belgian ales if you have to use both hands the entire time. It’s also pretty darn quiet, so I can listen to music or watch the playoffs while cleaning a batch of records. It is a little on the slow side, so if you have thousands to clean, you may want to consider something that cleans more than one a time. The price of entry is cheap too; around $465 shipped to the United States via FedEx. I love the Humminguru. It’s been a great investment for me.

Thank you SBAF for letting me hear these dongles. Its great to actually be able to hear them before purchasing. Here are my thoughts after a brief listen to both dongles. I don't think any prolonged listening is going to change my opinion, so I'll happily send these out to the next person on the loaner list.



All listening was done through either PC usb to Zen Pro, or Iphone 13 Pro to Zen Pro Balanced. I made sure to keep the dongles on until they were warm to the touch.

amb Ɣ2 technical measurements

Standard Prologue
If you are unfamiliar with audio measurements please use a search engine with the query:
"audio measurements" or "audio measurement handbook"
Look for publications by Richard C. Cabot and also by Bob Metzler, both from Audio Precision. There are other useful publications as well. These will provide basic knowledge.
Interpretation of the following measurements is beyond the scope of technical measurements posts.



Ɣ2 is eminently listenable. USB implementation is dated, however spdif + external power supply allow the Ɣ2 to perform its best. A far better auditory experience than the Original Generation ODAC.

By popular request, I've put the MIL boards into the Yggdrasil, let it warm up a few days; and these are my impressions after a few days on and off listening - at times wondering why my DAC sounded so "off", only to have to remind myself "oh, this is the MIL, not LIM".



I did this because I wanted to give the MIL a real shot. Not the quick shot I did before where I listened to it, said to myself meh, and moved on. By real shot, I mean more than my typical bullshit where I listen for three seconds and proclaim it to be shit. @insidious meme can attest to such stories. The funny thing is, I've never changed my mind. Additional listenings never helped. The most important thing in assessing any piece of audio gear is the control the variables: know the recording down to the specific master, know the amps, know the headphones, and maybe the cables (if you believe cables make a difference). People think I have great ears. I merely have a lot of practice, honing my skills with blind tests, and do a lot of little things (like what I mentioned above) to make it seem I am strong with the Force.

TL-DR. A platform to realise the sound potential of your 46mm drivers. Incredible build quality. Lightweight



I haven’t seen any reviews of this headphone online, so wanted to put down a few words. First, I should say that the complexity can be very daunting when you read about LTS. @Tomislav_L started an LTA project with several headphone designs, and it’s possible to make your own, buy DIY kits from him and assemble them yourself, buy complete assembled headphones or have customized versions made. And then there’s a choice of materials, mostly between 3d printed plastics or CNC’ed aluminium for selected parts.

If I recall correctly, Stax released the SR-L700 Mark 2 (hereafter called L700.2) a couple of years ago. I kinda completely ignored any electrostatic product news that time -- as my estat game seemed over in 2015 and I thought I was done with Stax.



However, I should have not ignored the L-series lambda lineup (at least its first revision, mark 2) which I originally thought was just a renaming or gimmick. After being thoroughly filled with wonders and wows for four straight days by the loaner pair, I’m almost about to pull the trigger on L700.2 for myself. These things are good.. Very, very good in almost every single way I can think of. They scratch nearly all Stax itches I had previously.

I knew Yamaha’s vintage models were frequently mentioned and loved by vintage ortho fans, but when I could borrow an actual pair from @Philimon, my expectation was far from being high. How can I have a hope for the combination of small drivers (for ortho), supra-aural drivers, and small closed-back enclosure? The list of such keywords sounds like a huge acoustic disadvantage. Well, I wasn’t 100% wrong. What I didn’t expect, however, was I ended up getting my own pair. OMG.



Before jumping into my thoughts, let me explain a little bit about my on-ear headphones history. I don’t think I have much experience with this type of headphones. Many years ago, I happened to hear B&W P5 and Beats Solo2, and liked them both. Grado couldn’t impress me but cut through via F-cushion equipped Hemp. For a stable daily driver, however, the former group lacks technicality while the latter was painful in ergonomics. So, that’s where I started my time with Yamaha’s vintage on-ear headphones.
