I have a SR1-a and the matching amp the HSA ordered and arriving in the next 2 weeks. My current favourite Headphones are the Abyss Phi TC's driven by a custom MSB Dynamic HP amp, with an MSB Select DAC and the Taiko Extreme. After having read your review and being a Wilson guy myself I cannot wait for them to show up!!

 

I will report on the sound of the matching HSA amp when they arrive. Better start a Thread on this ASAP, thanks Chris.

 

PS Also getting a custom set of DHC (Double Helix Cables) made up for the SR1-a's they need to be the same impedance as the standard cables.


what dac will you be using to feed the HSA amp?

This thread will work perfect -

That Taiko Extreme is... extreme...  While understanding this is a relative thing, is it worth that much money?


No electron left behind...

Worth is of course relative, but we’ll have a full review very soon. As in about a week or so.

Chris!!!!!!!! I just bought Meze Empyrean+Chord Hugo TT2. You're supposed to give me a "heads up".

Dying to experience these. 

Excellent review. Honestly I want to read superlatives if its warranted.


At least you could still use the great Chord TT2 to feed the required amp for the SR-1a.  😉

I think if I bought these I'd get an old Mark Levinson 332 to power these up. something big and bad.

I had my pair for about a week.  They were awesome, just as Chris reviews.  But the dynamics that Chris notes towards the end of his review were too much for me--the speed combined with the range was often like an explosion.  I was constantly fidgeting with the volume to avoid a headache, and I thought I would hurt my hearing over time.  It was like owning a Ferrari for a week.

Really now more than ever think I need to give these headphones another try.  I seem like the only one who didn’t like them on a short initial listen at CanJam NYC with the Schiit amp using the built in dac.  I wonder if my initial unfavorable impression might have heavily been influenced by the dac inside the Schitt amp???  Maybe the amp is good and the dac is so-so (or worse)??  Has anyone listened to these headphones with the Schitt amp using the built in DAC and/or done a comparison using alternate DACs?  

 

I think my use case would likely involve a Hugo2, but it would be interesting to go balanced into the HSA amp (or rca into the Schitt) using a very high quality dac or a set up using high quality tube amps into the amplifier resistance adjustment box.

 

Does anyone know how a potential buyer can get a demo?  Guess I can just email the company in the first instance unless someone knows a quick source (e.g., The Cable Company??).  Plenty of time to test headphones these days 😂

Listening to them now as I type this. Using the same APL DSD-SR DAC that I used for much of this review and the Schiit Jotunheim R headphone amp. The Schiit amp I received doesn't have an internal DAC. I can say that the sound is very good and nothing like your experience at CanJam NYC. Sure, it's a bit different without the built-in DAC, but the major difference is likely the environment.

 

I'm going balanced out from the DAC to the JR amp. All powered via 512 Engineering transformer. 

 

Getting a good demo is difficult during normal times, but now you're kind of on your own. Have to hope someone will ship to you and accept the risk of having it turned into B-stock if you don't like it. 

 

As much as we want to listen to flagship headphones, DACs, and amps at an audio show, and get results that mean something outside the show, the environment just isn't like our homes. it leads us to conclusions that may not be valid outside show conditions. 

 

I've long thought that CanJam exhibitors should contract with a soundproof booth company to bring in a bunch of booths to use as listening stations. I've taken a couple hearing tests in these booths over the years at audiologist's offices. They are great and really keep out the noise. There are portable versions as well. not sure if it makes financial sense, but it would certainly lead to great demonstrations of their gear.

I am sure you are correct on the demo.  Incidentally, I did reach a dealer within 1.5 hours of NYC (my home), and can likely demo in a few months (Covid issue) with the Schitt amp, then sometime thereafter with the HSA-1a, which the dealer anticipates ultimately having in store.  I’ve done a lot of reading since your review, and folks who own the HSA-1a speak very favorably about it as exceeding other amps (with and without the impedance box) by a substantial margin.

 

I am also interested in effecting some EQ for low bass and sub bass frequencies, which seems to work with these headphones. Aside from Roon and HQ Player, I am not sure how to do that, which is not ideal for me because I would be using this setup with a transportable rig (Hugo2 and 2Go as source) so no Roon server and no computer to run HQ Player.  Any ideas??

 

Bottom line is that if these things made you like headphones, they must be good 😂

I recently received a pair along with the Jot R amp and they are a revelation! I absolutely love them and they are addicting in a way. There are still times when I prefer the Meze Empyreans, because the SR1a earspeakers require your attention at all times, but most of the time it's the SR1as. They are so transparent and so musical; a clear window into the performance and instruments. 

 

They might replace my speaker listening when I really want to listen to music because my room is not optimized. With the RAALs I just sit down, put on the music (Roon) and go. Deep bass is the only thing lacking (i.e. Daft Punk), but otherwise bass is clear and fast and real. My Harbeth P3ESRs also can't go deep, but they are musical in a similar way. 

 

I read another review that included a prototype Jot which they described as "brittle" sounding at times. I have only heard the RAALs on the Jot R and I'm curious top hear other impressions vs amps. I can only imagine that introducing the "middle man" converter would take a slight edge off of transparency, but perhaps better amps have their own qualities that are appealing. 

 

Like I said, a revelation! There's no going back.

The header accepts votes from anyone scoring the review. I know this is confusing. I would’ve given these 6 stars if possible.
