Schiit Freya Modes: Subjective vs Objective Differences

Longtime lurker, first time poster here, thanks to all the contributors to this community over the years.

I’m curious if anyone has had experience with a firm subjective impression being negated, or at least complicated, by objective testing.

I recently purchased a Schiit Freya Noval unit and have been driving it hard and testing its output modes for the last month. I very much enjoy it, regardless of the following.

Ignoring the SS buffer for now, my impressions of the passive mode are that it is clean, clear, detailed, and transparent, at the cost of the lower midrange down feeling a little thin, as if the backing band is a few steps farther away from the singer. Vocals are prominent but the soundstage is a tad narrow. The tube mode on the other hand feels a smidge richer and fuller, with male vocals and acoustic guitar in particular having extra presence, weight, and warmth. The bass is more articulate and extended, and a pleasant haze falls atop the presentation, softening harsher details and making the soundstage seem wider and airier.

Or so I thought.

I decided to record the outputs of the Freya with a high end video capture device I use for work that has analog inputs. Using test tones, scopes, and the stepped attenuator, I’m able to achieve a dead-nuts exact level match between the two modes prior to making 24-bit/88khz recordings of a handful of songs spanning different genres. I sync these up in my editor program, and am able to instantly A/B them live listening with my Sundara headphones, sighted or blind.

The result: no difference. No difference as in truly zero difference between the passive and tube outputs. I’ve done this test in a few other contexts with other components before and always find some little detail I’m able to latch onto to establish a contrast, but not this time. Classical, bluegrass, rock, reggae, doesn’t matter: the passive and tube modes give the same output in my test.

Assuming for the sake of discussion that my methods and analyses aren’t flawed, I see two possible explanations:

Either A) The differences exist, it’s just that they are due to the interplay between the Freya and all downstream components in my main listening area, and therefore cannot be heard directly from the Freya to the capture device.

Or the dreaded B) There are actually no differences at all and this is purely one’s brain and ears, the collected influence of reviews and audio forums, confirmation bias, and the imprecision of level matching the modes while listening, playing tricks on me.

What do you all think? Is this something you have experienced as well? Thanks for reading and for sharing any impressions.


Hi @mattw73 , no worries happy to provide an update.

I didn't end up pursuing my findings with Schiit, though I continue to be a happy camper using this preamp and would encourage you to pick one up if you can still get one, especially with the balanced options. It's a steal.

I learned shortly after my last post that my microphone was no longer compatible with my recording software so I put a pause on further recording and have just been enjoying the music.

However, I have a UMIK-1 in the mail right this second as I was interested in exploring convolution filters within Roon and HQPlayer so I might pick this back up and can let you know what I find.

Regarding my experiences in the subjective realm, I've tried out some additional NOS combinations, and I feel there are differences, but they are definitely subtle. Most notably, there seems to be less energy and dynamics whenever you deviate too much from the recommended 2.4A heater current total of the four tubes. Using 4x 6922s just feels too mellow for instance, but adding 2x 6N6Ps to the output side restores the excitement while letting some of the character of the 6922s come through, which with my Bugle Boys, I interpret to be a tiny bit of warmth, with a slightly wider and more holographic soundstage compared to the SS Buffer. As tempted as I am to spend $300+ on a pair of NOS Mullards, I just feel that this application wouldn't do them justice. Luckily 6N6Ps are plentiful and cheap though.

So in short, I think you're right to call this an entry point to tubes, but it's still worth it in my book given the range of features and strength of the solid state modes.

Thank you @nixanthrope , I truly appreciate the response and opinions you've shared.  I have an opportunity to get my hands on the Noval for a used price..and for the money & features it will be hard to pass up. Seems like it would be an easy resell down the road if I discounted the price a little bit. Thanks for your insight on the tube pairings. I actually have a few pairs of old well regarded 6922's I never had the chance to use. Some GE labelled Mullards, Phillips Holland Miniwatt SQ's and one pair of PQ's that I spent a decent amount on many years ago. So a pair of those and something with a little more power seems like the way to go...yet not going over the 2.4 mark. 

I'm glad to hear that you are still using the preamp and enjoying it. Awesome 👍

@mattw73 I think since you're already stocked up with options, it's a no brainer and you should go for it.

Buying second hand might break the warranty, so maybe have a look at some QC issues others have experienced here before pulling the trigger (I personally haven't had any, mine is a good unit):

And if you're stateside, ebay seller "kambremer" has US stock Russian 6N6Ps and 6N1Ps for good prices. For the latter, you can get a matched quad for cheap, which is better than what the Freya N ships with. I also recommend trying 4x NOS 6CG7s which will also give you the full 2.4A.

Good luck and Happy New Year!

@nixanthrope thanks for the heads up and link to some real user issues. Information sharing like this are what Forums should be all about. I'm glad I reached out and you were kind enough to spare a little time and share with me. 

Happy New Year!!
