Before I start my impression, I just want to thank @E_Schaaf and @ChaChaRealSmooth for making this possible. I’m grateful and feel privileged to be able to audition gears in my setup without committing to expensive purchases. I happen to get both the Pathos and the Euforia delivered to my house on the same day so I had a busy weekend trying to write impressions. My setup: Gungnir Multibit A2 Gen 5 > Auris Pathos / ZDT Jr. | Valhalla 2 > ZMF Verite/ HD650 Overall tonality seems to be similar to that of other tube hybrids like Lyr 3 and LP. I didn’t hear any glaring faults, but it didn’t amaze me with any outstanding qualities. Aesthetic reminds me of Focal Stellia with those holes (aka trypophobia trigger box), BUT looks more pleasing than LP. LP looks atrocious imo. Unit gets warm but not hot to the touch like valhalla 2 or scorching hot like ZDS. Versatility: you can fine tune the gain level to match your headphones: place the volume knob at the middle and increase/decrease the gain until you’re at the appropriate listening level to properly match each headphone to their respective impedance. Handy dandy amp that takes balanced, 3 RCA (I think) and tape out. Decent macrodynamics but lacks in microdynamics. I don’t find it as engaging at least with my setup. Maybe it’ll be different with planars? I think this is the amp’s biggest weakness if I had to pick. Good clarity. Verite didn’t sound veiled or dark. Treble is well extended with plenty of sparkle and lacks harshness or stridency. Bass is not bad, but didn’t sound as tight and authoritative as Jotunheim. Lacking a bit of slam? I wished the mids were a little more forward. It’s a bit laid back/polite for my taste. HD650: mids are not as forward and aggressive sounding as ZDT Jr. Smooth treble. Overall tonality reminds me of lyr 3 Lacks a bit of body and warmth. stage is meh. I was hoping for a bit more at this price point. Verite: Valhalla 2 sounds noticeably slower when I listen with the Verite. Fast passages are clearly defined and incisive. No over smoothness Headstage is smaller and lacks a little bit of depth compared to Valhalla 2 Overall resolution is about right for the price point. Verite pads helped with the macrodynamics but still found it a bit lacking in the microdynamics. Also vocals do not sound as smooth with this pairing. Smoother overall tonality than Val 2. No sharpness or stridency in vocals ZDT Jr. has noticeably better macro/microdynamics. Although the stage is rather smaller, there is more contrast between the quiet and louder passages. Andromeda: Hissssssssssssssssssssssssssssssss. That is all. LOL (even at the lowest gain) I wasn’t able to tube roll since I don’t own any extra tubes that fit this type. S-Booster LPS: oh wow, I like this a lot. Increased sense of immediacy and stage slightly. Music sounds a bit snappier and immediate. Maybe it’s placebo… the change is more apparent when I listen to classical music. Doesn’t sound as constraint as with the stock power supply. I spent most of the time listening to this amp with the Verite. I thought the synergy was better than with the HD650, still not amazing or anything. S-booster led to some surprising results, but I feel like I would need more time living with the unit to do a proper evaluation. Overall, I think this is a technically capable amp for the price, but I don’t see myself reaching this for this amp if it was mine. Maybe I just lacked the headphones with the right synergy, but I would rather have the Valhalla 2 or ZDT Jr which is more affordable and engaging to listen to.
