I wish I had the dosh for this and the power supply. Those filters seem like some next-level engineering. Another listen at AXPONA is in order for sure. Thanks for the review and your succinct conclusion- a great way to spend 1/3 to get $10k sound.
Doesn’t it work without Cardas Clear Beyond Belief cables?

Elvis Costello just approved of the latest iteration. The cables work fine.
I had liked to see measurements published comparing between HYPSOS and the wall-wart supply.
Or maybe just clearly mentioned if there aren’t any differences.
BTW: There’s a little typo in the underline of Fig. 18: “… output power into 8 ohms” should be 100 kOhms.
"The distortion in both output types was extremely low at all audio frequencies, and the second- and third-harmonics lay at or below a vanishingly low –120dB (0.0001%) into high impedances (fig.19). This was the case with both the HYPSOS and wall-wart supplies.
Even when powered by its wall-wart supply, the Ferrum Wandla performed supremely well on the test bench with both analog and digital inputs, especially with the HQ Gauss reconstruction filter. It boasts very high resolution, very low distortion and noise, and a bombproof output stage."

I agree with you, it is very interesting to compare with and without things. On a slight tangent: pre and post "break in measurements" of things, especially speakers, could be very enlightening!
Cheers.

The only difference I found and wrote about was that the random noisefloor, which was already low with the HYPSOS supply, was 6dB lower with the wall-wart. All other measurements were identical.

Thanks. I have fixed it.

"was 6dB lower with the wall-wart. All other measurements were identical"
No need then to blow $1200 for the Hyposos power supply, the wall wart should be better, looking at the measurements.
Any wattage specs on the wall wart??
Cheers George
I'm wondering if you tried using the Wandla as a preamplifier. Can it do double duty, or would you still need a separate preamp to get great sound if your other source is, say, a phono preamp?

The Wandla's measured performance as a line preamplifier is beyond reproach.

I continue to search for that next level with my fairly large CD collection, within my $ comfort zone of course. This Wandla would be stretching it, but I am really intrigued by the filter and voltage flexibilities and their impact on sound.
So... Herb, you auditioned many streaming selections in 16/44.1. Helpful.
For you, and others with streaming experience, what have you found with streaming versus CD's in general? IOW, can I generally extrapolate Herb's 16/44.1 streaming experience to what my CD experience might be?
Currently, depending on the disc, I switch between my old Marantz SA-8004 on board DAC and my MHDT Orchid R2R DAC. Both are quite nice. Both leave me feeling there's more to be had from my CD's. Friends, please tell me to knock it off if I'm just falling victim to audiophilia nervosa...
Meanwhile... thoughts on getting the most out of my CD's welcomed.
Speaking personally, I play files and stream music in all resolutions rather than play silver discs. It's easier, consumes far less space, and sounds great. As to which sounds better in 16/44.1, file playback / streaming the same files from Qobuz or Tidal / playing the discs, it depends on the quality of your playback software and hardware. On my system, the order of sound quality, with the best on top, is:
Files stored on my Innuos Statement Next-Gen's internal SSD
Files streamed from Tidal and Qobuz
Files sourced by my NAS which is powered by a Ferrum Hypsos hybrid power supply.
Note that my streaming network is highly optimized with an optical interface and top-quality ethernet, USB, and power cables. It has taken a lot of time and money to get where I'm at.
Short answer: There is no absolute "this sounds better than that." You need to experiment and listen.
I hope this is helpful.
jason
But in a more immediate sense, what I am really after is how to optimize what I currently have, i.e. a few thousand CDs (along with probably 3K LP's, and a hundred or so reel to reel tapes).
I have heard enough goodness out of the variety of affordable DAC's and players I've owned that I can tell there is more to be had. The greatest change (mostly, but not always, for the better) I've experienced has come from the R2R ladder DAC rabbit hole. More analog sound though at times with the loss of some detail and vitality.
So, because of the significant differences experienced, I suspect I can do still BETTER, but my budget is not 5 figures deep for DACs, dedicated transports, separate power supplies, etc.
I guess my real question is this then: based on the experiences of my fellow music lovers reading this, what have you found (IF anything) that generally takes CDs to the next level? And, by the way, my food chain upper end in toto for DACs, USB cables, S/PDIF cables, power cables, etc. runs to maybe $5K for the sake of my marriage, budget, and conscience.
I have been tempted to jump into the Benchmark pool, the Bryston pool, and some other pools, but hesitate because, though auditions and 30 day trials abound, I have found that I really have to LIVE with a piece of gear for the long haul to truly know...
You pays your money, you takes your chances. For that reason, and that fact that most DAC reviews don't spend much time on CD reproduction specifically, I reach out.
No expectations, just sharing. Thanks for the feedback thus far...
Mark in Santa Cruz
I'd check out Herb's reviews of lower priced DACs. Also consider that the very first power cable in your chain has ramifications totally down the line.
Easiest solution. Many of your CDs are undoubtedly streamable, and some of those streams will be hi-rez. Put Qobuz, Tidal, or Roon on your computer, get a better cable interface, and connect to a streaming DAC.
Here's to long-lived relationships, with music helping to magnify the joy.
jason
And this brings me alllll the way back to what motivated me to write in the first place: this DAC under review by Herb is quite intriguing specifically because of the fact that the user has a lot of options to shape the sound.
Maybe I should just take the leap... (insert shrug and forehead smack emojis here).
See my assessment of the Ferrum front end at the Warsaw show. I was surprised by how good it sounded. You can always go with just the DAC and then spring for the Hypsos later on. If you don't hear the difference immediately, perhaps you can return. I'd check with them.
Taking a flyer on a Wadla with the ridiculously gracious encouragement of my wife along with Herb and Jason.
We shall see... er hear. Looking for endgame DAC for CD's. Perhaps?
And thanks for the tip on Audirvana. Will check it out!
Will charge you for the restock fee the last time I checked when I bought my HPA4 and when I returned cables that I didn't need. Important note to factor in when buying from them. You should be quite happy with their products, though I realize you would be looking at DAC3 family.
Thanks Glotz.
Hopefully the Wandla is a winner in my system and a return or resale is unnecessary.
Was leaning toward trying a DAC3 but... the flexibility of the Ferrum as extolled by Herb tipped me that way.
Also, research quickly revealed that an in-shop audition of this kit is nigh impossible anywhere near me. So I'm jumping in!
Now I wait in suspense to learn if it gives you what you want, or if the entire experience leads you to question the feedback and opinions of HR and JVS. Once your new baby settles in, please send an email and let me / us know. If you can't find our addresses, write us c/o stletters@stereophile.com.
Thank you,
jason
You're a good cheerleader JVS.
Over the many years, I've never been misled by wise ol' Herb or the late, great Art D. As for you JVS, I've never really had the chance to test your audio judgment and wisdom, mainly because I'm in a much lower audiophile price orbit. But your feedback here was a good nudge.
Will report back when the new unit is broken in and making music. I'm looking forward to some fresh deep dives into my Mercury Living Presence boxes in particular, followed by a lot of Bill Evans, Joe Henderson, Lee Morgan, and many more.
This is a great hobby and dare I say family, conflicts, warts, and all.
Do check out Tom Fine's latest remasterings of the MLP catalogue.
if my first set of notes got to their intended recipients or if said recipients care, but either way, here's a retry
Since I wrote the below, my listening has gotten much more extensive of course, and I'm pretty excited by what I'm hearing. So early impressions below, more to come.
Oh heck, preview of the more to come: clarity and vitality I have been wanting, soundstage GALORE, high end extension, musicality. One latent concern...
I'll keep any readers, or the ether, in suspense on that.
From a couple weeks ago:
Life With Wandla, Part 1 (per JVS invitation)
I have a new crush and her name is Wandla.
My wife's OK with it, she's a Polish DAC. Wandla that is, not my wife.
My impressions thus far (early, early in the relationship) include the following:
1) Holy Kumquats! High end extension and detail in spades compared to my back-burnered MHDT Orchid and Marantz on-board DACs. Or is it digital etch and glare that shines at first then quickly grows wearisome?
TBD. Much break-in and filter experimentation ahead.
2) First listens to a couple of MLP monos from big CD box #1 were not promising. Kubelik's CSO string section bailed out in favor of several dozen sharp-clawed cats with tiny little chalkboards.
However, several hours break-in later, Joe Henderson and buddies (from the great Mosaic box set) provided a sweet and open top-end. Hoping that Kubelik's strings will return. Sooner than later.
3) SOUNDSTAGE. Silly deep and wide (even outside the the width of my Falcon LS3/5a's) Never have I heard such breadth, depth, and layering from CD's. Switching back to the Marantz, everything collapses overbaked souffle like.
This could get interesting. It's already fun.
Mark in Santa Cruz out.
I'm very happy for you. May the fun increase.
jason
PS. When I have a product that requires break-in, I try not to listen at all until break-in is complete. First impressions are often not lasting impressions. Nonetheless, sometimes I can't restrain myself.
though I do enjoy hearing a component evolve over the first dozens / hundreds of hours. It's a rather fascinating process to hear changes over this time from a static piece of electronic kit. Still a bit of a mind bender to me.
So, I tend to play a lot of music in the house with a new component only settling in to listen closely periodically to "check in." Ferr instance, listened to an old gem last night, Al Jarreau's "Tenderness." Oh. My. Goodness. Once again, space, room, expansiveness galore, even in my small listening space. Bending the laws of physics, one disc at a time...
Planning to get back to the old, offending (and early) MLPs today or tomorrow to hear whether the cats are still around or the string players have returned. Perhaps it's just the recording and my MHDT DAC higher frequency softness tamed the harshness. TBD.
Thanks for listening, er, reading.
OK, I give in. The Ferrum Wandla is all the reviews make it out to be and more.
I've never heard CD's with so much body and soul, and warmth without sacrificing detail and vitality.
And, as I have mentioned, sound staging galore, including height like never before in my system with digital.
So glad I took the leap, and this without even going to the Hypsos PSU.
Yet.
And to add to the fun, this piece of kit comes from near the epicenter of my heritage - northern Slovakia / southern Poland.
Well played Wandla for the great work and stupid high value, Herb for capturing and communicating the essence of this piece, and JVS for the nudge (or shall I say benevolent shove :) to dive in.
Your Orchid dac is similar to the Pagoda save that uses the TDA1541 chip while the Pagoda uses the PCM1704 chip (which I think is the better) but the way both are implemented leaves a lot to think about, as the distortion figures are through the roof at nearly 1.5%!!!!! and below 80dB dynamic range. I would look to a new dac that is at least <.005% to get more enjoyment from your CD collection.
Cheers George
streaming = casual
vinyl = natural
cd = intense
