RAAL-requisite SR1a Has Landed


Recommended Posts

I am not really a headphone guy but I saw some video’s and read some reviews and people seemed perplexed by the sound quality. The reason I do not really like headphones is that I like the soundstage in front of me and not in my head. I understood that raals image differently is that true?

Back at it this am, listening through the SR1a. 

 

@TubeLover, I'm checking on replacement tubes for the MC275. Do you have any other amp recommendations you'd like me to get in here as part of my evaluations?


What about a class-d amp, they have the power and a “tube” like sound.

The problem might be that it all gets too natural and too fast.

Sorry no experience with them. But the small AGD looks nice, can deliver 30A.

wow that look awesome. I wish I could have listen. 
Are you going to pair sr1 also with the schitt JOTUNHEIM R?

Sweet! I hope the tubes aren't making your Rossini sound like Rosh-ini!

 

Just kidding - I love A-R gear.


Have you tried the Raal’s yet? Love to hear what you think.

Also wondering if all that ribbon speed spoils listening to speakers?

I could not wait for another glowing (sorry, more tube puns) review. Ordered my Raals today, shipping tomorrow from Amsterdam. Want get them before the spike in demand from all the positive review and impressions causes a global shortage.

 

Going to use Ncore monoblocks short term for motive power. Probably go Jot R soon, then look for some exotic amplification later on. 

 

Chris, you probably pushed me over the edge. I appreciate it.


please let us know how they do with the ncore’s?

Is Amsterdam the only place where you can audition them, that you know of? According to google it is?

Do you by any chance know how these ribbon headphones differ from the ribbons offered by HEDD Audio's HEDDphone?


These are ribbon speakers.

What if you have only one power amp for your speakers and the raal. What then, connection wise?

I need to try one in my kraal then!


😁

I must say I am a bit astonished you stil haven’t, you being a headphone guy.

I really thought you would jump on the raal and would write the review Chris is now writing. It really sounds like an amazing thing and even I am tempted for its near ideal sound reproduction qualities, maybe?.  But I also want a Bartók and a couple of Cube audio drivers and audio analysis speakers.

Ted, to my knowledge, your Jotunheim is the only direct-drive amplifier out there that eliminates the interface box.

But on a more serious note, it looks awesome. With what amp did you pair it with to listen to raals? Hope to read the review soon.
Edit: also wondering how it holds up to the Bartók.

 

In the future when funds allow I’ll probably buy or diy a Purifi class d amp.
I think because of it’s un-colored sound and speed in high current delivery it’s well suited for the raal. And pair that with a tube pre-amp to add some tube magic.

I have asked Meitner if I could use the single ended and the balanced output of the ma1 simultaneously and they said it was possible. 
So this is at least for now the plan I dreamed up.

I'd be careful here.  If there is a disadvantage to the RAALs it is that they are too quick already.  That "straight wire" might be more than you bargained for


I have found a couple of reviews where people did that and they were happy with the results. 
In one review they even paired a Nagra classic with a Purifi and a Raal with very good result.

I've been thinking diy Purifi too, the older Ncores worked pretty good into the Raals, but the JotR works better for me. I'm thinking Hugo TT2 (unless that gets replaced Mola Mola stylee) in AMP mode into the Purifi module without buffer. 

 

Question is just how transparent that interface box really is.


Did you experiment with the input buffer opamps? This might be the key to getting the sound to your liking. You can even get tube input buffers it.

The Purifi or ncore is just there to have no sound of it’s own and deliver the drive to the raal. At least this is how it could work in my mind.

My pre-amp has two pairs of rca outputs so two power amp would work.

 

I have searched a bit on the www for 100w tube amps but proves to be expensive.

But for now my Sovereign amps have to do. I really need some experience with other amps.

Sorry it took some time to say something on my new Raal headphones I am not a very good writer.

Second is, I have never heard high end headphones before so I needed some time to get use to the experience. 

The first question I had was if the raals spoiled you from speakers. Well no they didn’t I still like my speakers but the raals do a few thinks better. Bass for instance it is very articulate and very well defined and because of that it sounds more realistic then with my speakers. Not surprisingly if a few milligrams of cone mass, instead of 55 grams (10” ) have to reproduce it. With regards to bass amount it depends on the recording, for me all via tidal, listed below for reference.

 

I would have liked the sound stage a little more in front of my face. The  depth seems to be projected from the drivers to behind your head. It’s like having your chin on the podium with the applauding people behind your head.

All in all these headphones are very nice to have really enjoyable, they are like a stethoscope into your system listening unfiltered to your systems character. 

How much break-in time does the raal needs? And also a clip for the cable would have been handy so you could clip it on your blouse.

 

 

  • José James, Blackmagic via Tidal comes across as a nice bass amount. Very nice
  • Ane Brun, After The Great Storm, comes across as nice bass amount.
  • Kate Bush, Aerial, an endless sky of honey, the birds at at 19:20, the track very nice.

Hi Guys, I continue to enjoy the SR1a every day. I believe I have the absolute best sound I've ever had through them right now. The Constellation Audio Inspiration integrated amp driving them is off the charts awesome. 

 

On another note, and I hope I'm not speaking out of turn, RAAL-requisite sent a pair to Mitch Barnett for measurement and to work with me on creating convolution filters to make the sound even better. Mitch sent me is preliminary opinion and measurements. As the are very preliminary, I'll only post his first two sentences. 

 

I hope he'll write up the whole process of listening and measuring and creating a filter to improve them even more. It would also be cool to see Roon integrate these types of DSP options like it does for Audeze headphones.

 

Anyway, here's Mitch:

 

"Chris, These sound and measure fantastic. I mean they are pretty close to ideal..."


Where would it be best to implement the dsp without loosing SQ? A dsp dac or dsp amplifier or one of those minidsp boxes?
