Here's a summary of my notes I took from my time spent at the Schiitr with my ZMF Verite (VO) a couple weeks ago. Hoping this serves some people to get impressions of how the VO pairs with various Schiit amps. All listening was done with the Verite lambskin pads, and any amp that features XLR output, only the XLR was tested.
- Jotunheim (+ Multibit Card) - Hi-Gain 9:30 o'clock - Nice dynamics. Bright. Nice detail resolution. Very nice slam/impact, bass transients are fast. Layering and separation could be better, can get congested sounding. Black background.
- Asgard 3 (+ Multibit Card) - Hi-Gain 12 o'clock - Not as dynamic as Jotunheim. A bit lacking in sub-bass, full and present mid-bass. Somewhat busy and congested. Treble seems uneven, although not as bright as Jotunheim. Slam is good, but not as fast as Jotunheim. Stage is more 3D than Jotunheim, felt similar to ZDT Jr in this regard, more frontal depth to stage. Seemed "powerful" but didn't have full control of driver.
- Valhalla 2 (+ Bifrost) - Hi-gain 11 o'clock - Slight noise from tube + scratch from volume pot. Highs are dry and pronounced. Bass has quantity but also bloomy. Stage depth is good but imaging is blurry. Poor dynamics. Mid texture is good and engaging. Highs uneven, somewhat aggressive sound. Upper-mid dip of Verite is more noticeable here. Feels V shaped.
- Lyr 3 (+ Multibit Card) - Hi-gain 10am - Coherent sound. Significantly rolled off detail. Lacking snap and speed. Poor micro-dynamics. Flat stage, poor imaging.
- Mjjolnir 2 (+ Gungir Multibit) - Hi-gain 9:30 o'clock - Major improvements to separation and layering. Powerful and full sound, while maintaining excellent detail and texture. Very articulate and fast. Bass texture is great, slam is excellent. Micro-dynamics are superb. Mostly linear sound, although some songs felt slightly bright. Pleasantly airy. Nice stage width.
*As a side note I felt the Gumby is creating a good deal of the sound improvements with the Mjolnir 2. I tested both the Gumby fed into Jotunheim, and the Jotunheim's MB Card fed into the Mj2 as well. The layering and separation of the Gumby is clearly superior, as well as detail retrieval and staging. However, the Jotunheim was unable to deliver these improvements in the same fashion that the Mj2 was. Tonally the Mj2 was superior to the Jotunheim when paired with the Jotunheim built in MB card.
Overall I spent about 3 hours listening to the various amps and DACs.
In order of preference I would say; Mjolnir 2, Jotunheim, Asgard 3, Lyr 3, Valhalla 2.
The Lyr 3 suffered from too much detail roll-off to be worth considering with the Verite in my book.
The Valhalla 2 had that least linear sound signature with too many other faults.
The Asgard 3 was generally "good" but didn't excel in any area other than nice stage depth.
The Jotunheim had a lot of positives but it was definitely bright, but since the Verite isn't a brighter headphone I think this pairing was good.
The Mjolnir 2 (with or without the Gumby) had the least negative adjectives in my notes, and the most positive. The Mj2 seemed to have the best control of the VO driver and nice stage benefits of having tube (hybrid) design.
*Another side-note: FWIW, I've previously owned the Modi 2 Uber, Modi Multibit, Magni 3, Asgard 2, Valhalla 2, Jotunheim. I wouldn't call myself a proponent nor opponent of Schiit products. I have had success and enjoyment from owning their gear over the years, but I wouldn't go out of my way to own their products either.
Since my visit to the Schiitr I purchased a used Mjolnir 2 and have been enjoying it. I have a Liquid Platinum coming in the mail tomorrow as well and look forward to spending a good amount of time comparing those two.
Cheers.
