The Hestia is a 60 stepped relay attenuator. The flagship Denafrips preamp, the Athena, has the same specs with lower distortion numbers. The Athena by the way looks to be two Hestias in one box - one Hestia per channel. The same way the Hattor Big preamp just doubles up on the stepped attenuators when you step up from the Hattor Mini. I only mention this because I was originally going to buy the Athena, thinking bigger was better until I studied the specs and pictures a bit more - mainly noticing that despite double the number of relays the number of volume steps remained unchanged. I seriously doubt the two preamps sound any different. Folks at ASR might be willing to pay for the lower distortion numbers though. New, it will cost you about $900.

Introducing the Sennheiser HD800 S Mordred from Excalibur Edition. Nope, you can't have this. At least not in the USA. It's my understanding that this limited edition headphone is sold out. It may be possible for folks in the USA to buy from Europe and have them shipped here. I hate reviewing stuff that people can't have, but at least this is interesting.



By the way, the HD800 S Anniversary Edition seems to be quite different from the HD800, and by extension, a little different from the HD800S. It's still an HD800 in terms of soundstage, timbre, transients; but the subjective tonal balance seems a bit different. I could be dreaming though. Will put this on the bench to confirm, but my sense is that the midrange dip is more evident, the 6kHz is no longer existent, but the highs are still up there. Also, the bass quality seems more in line with the HD800 than HD800S which sounded thicker to my ears (this is a good thing).

I'll post measurements over the weekend, but will start with subjective impressions and usability notes. In a nutshell, if I had an entry-level phono setup, I would immediately buy this over anything else on the market for less than $800, heck make that $1500 even. The fact is, the vinyl-nutjob world has been dominated by the www.orfas.org for far too long. Basically, anything below $1500-$2000 for a phonostage from well established brands will be a severely nerfed product.



With the ZEN Phono, the "nothing better until we spend much more" argument is still valid, but there's also buy this because it's actually very very good. To be honest, the $149 price is absolutely shocking. With iFi, I would expect $399. But heck, let's see iFi bring it on for the masses. I hope iFi sells thousands and thousands of these.

This has turned into a rather long review roundup because I kept writing impressions about an iem and then I’d find a way to make it sound better and write a new review. For a couple iem’s this happened a few times. But I’ve decided to include all the reviews because it is great testimony to how challenging it is to review iem’s or compare impressions. There are so many factors with iem’s that don’t exist with full size headphones- (tips used, the way the tips fit - depth of insertion, how tightly they fit affecting the seal, the way the iem’s sit in your ears which changes how the tips sit in your ears, and the source used which is an especially big factor for BA iem’s with wacky impedance curves causing them to change FR with different output impedance). So I’ve left them in to give important evidence of how fickle the sound you get with iem’s is. If this was a full size headphone review roundup I would only have one review per headphone.

List of rhythmdevils recommended neutral iem’s in order of price not including aftermarket tips:

• Surge+ dynamic waterproof iem 40$ now on sale otherwise 50$ - ever so slightly warm, great tonality.
• EDC3 100$ on drop.com with optional modded Symbios F Peel tips if stock tips are too small - neutral
• Sony M7 500$ now with Sony sale otherwise 700$ With Azla Sedna Earfit Light (NOT short) - neutral
• CA Androeda 2020 1,099$ with Penon Audio tips (see review for link to tips). - warmer than neutral but extremely resolving and fast
• CA Ara 1300$ with Azla Sedna Earfit Light Short tips - the most neutral iem I’ve heard with deep insertion.
• CA og Solaris 1499$ with normal not original or + or ++ tips - neutral

The Apollo is a hybrid DD + 2 BA IEM. I don't know if the world has changed much, but typically hybrid IEMs that use two or more different types of drivers have always had integration issues.



Where I will start is that I do expect the band members, or the drivers in this case, to play as a band and not as individuals. I don't expect the timbres of the different drivers to sound the same, as this is impossible, even with multi-way speakers. However, I do expect that the frequency ranges where the drivers overlap and hand the signal off, to sound cohesive and as seamless as possible. This is just one of my pet peeves, whether it comes to multi-driver speakers or IEMs (sometimes I wonder if folks outside of SBAF notice such things concerning overall cohesiveness.) The good news is that California Audio Technology or CAT, manages to pull this off with their Apollo hybrid IEM. The driver integration is on-par with another hybrid IEM that pulls it off decently, the Campfire Audio Solaris. That's two IEMs in my book (there may very well be more today, but I have not gotten my ears on them yet).

I received this unit from @Armaegis a long time ago. Being as it may I only recently opened the box. It's been incredibly busy at work with all this SARS 2.0 issues and so on. However, I'll do my best to review this unit. In many cases I start by listening the unit and then proceed to capture random measurements. This time I did it backwards. I started taking measurements first. I also took pictures. But I'll upload those some other day.

Balanced full scale in this unit seems to correspond to 6.22 Vrms, and so this will be 0 dBFS which in the plots that will follow is dBrA (referenced to 6.22 Vrms).

THD characterization at 4 Vrms are shown below:


We get THD+N of 105 dB (A-weighted) with 3rd harmonic slightly dominating the 2nd harmonic. Note also the delta-sigma modulated noise is effectively suppressed above fs/2 = 48 kHz.

Through a few chance encounters I became very interested in vintage audio and started collecting old audio equipment, manufactured long before I was born. These experiences forever changed my approach to audio in general, and this year I decided to return to playing with headphones, with a focus on vintage and out-of-production models.



This thread will chronicle my experiences with a few select models I have had the chance to own and hopefully serve as an inspiration for others who may find themselves a little bit bored with the state of the modern personal audio market. For members who have been around longer, some of this may be 'been there, done that', but please feel free to contribute your thoughts on any models discussed

Gaudio Labs is a Swiss company new to the IEM scene. You might have read a little about their beginnings and design process here at SBAF on Nico’s thread:

Their first two in-ears, Nair and Clariden are of premium build with ergonomic aluminum alloy bodies. They have a natural silver anodized finish with acrylic logo inserts on the faceplates. The nozzles are polished stainless steel. Everything is machined to look and feel premium, and frankly Gaudio succeeds fantastically. All the kilobuck brands out there need to take notice. This is how it’s done. The look is somewhat reminiscent of Campfire Audio’s industrial build but possibly taken to the next level, particularly in regards to ergonomics and weight. And I can’t say enough about the ergonomics. I was able to give Nico feedback on a very, very early prototype a long while back and a large piece of that feedback was the fit. It was pretty painful. I’m not sure how he went about tackling the fit issues but these housings fit superbly and I have zero complaints. This is an excellent universal housing with custom-like fit. Bravo.

As much as I couldn't imagine to become a grado fanboy, I didn't regard myself as a potential customer of v-moda headphones. .. at least until this year. I know Tyll loved them (during IF's good old days he wrote multiple posts showing his big love). But when I actually heard them, I thought I was too noob basshead to rock with vmoda.



A few years have passed since then. Many things changed. Grado became my top go-to headphones, sennheiser could terminate long love-hatred relationship (in a positive way), ... and I am about to ramble about v-moda headphones, Oh, well...

But later I found some of v-moda's older fans hated m200. That's quite promising green signal as I always believe criticism from fanboys and parise from skeptics are the most sure things in the world.

In short, this is the tube amp that I had wished I had started out with when I was near the beginning of my headphone audio journey many many ago. I instead went in a few other directions from all the HF buzz - all the wrong directions - but this is a solid entry level transformer coupled tube amp. (Note that this is the first version that uses 6DE7 tubes).



Honestly, I don't think there can really be such a thing as a bad sounding output transformer coupled tube amp. What is comes down to to how much performance do we get for the price. At $1300, the Woo Audio WA6 SE is high value. I'm still kicking myself for going off in various random directions early in my journey. I remember reading about the WA6 SE on HF and almost pulled the trigger. (BTW, the construction of the chassis is bonkers solid.)

This is the 3.1 version of the Mysphere, or the "portable" version which is supposed to be easier to drive from modest sources. Depending upon who you talk to, the Mysphere 3.1 is either the less technically strong or the one that is neutral, fast, an detailed. The Zout of the amp I'm using is less than 2-ohms. The 45 custom is transformer coupled and has a little bit of feedback. I also tried it out from the Motu UltraLite's headphone output, which had no problem driving the Mysphere.



I spent some time listening to them for a few hours to get a subjective impression without the "benefit" of measurements. The drivers were oriented fully outward during both subjective and objective testing. (What's the point to keep them closed in like regular headphones!) In my time, I noted the following characteristics:

I learned from @Gazny about a new “startup”, if you could classify it as such, known as Nectar Sound. They were producing electrostatic headphones out of their garage, but touted the experience of an electrostatic, while keeping the redeeming qualities in dynamics that I wanted, primarily impact and bass. I quickly reached out to Sajeev, the owner to inquire about his headphones, and upon talking to him learned that Bottlehead had created a tube energizer to match his headphones. I quickly pulled the trigger since it seemed to be exactly what I wanted, and with a higher end amp from Bottlehead it would be a good investment for other electrostatic headphones in the future. The price of the headphones are $600.
