Hi, Everyone.
This is my first time back posting on the forum again in about two and half years, and this amp managed to drag me back in (so to speak). A little background first.
Last time I was here, I was finishing up my senior year going back to college full time for engineering as a second career. At the time, my main setup was a Bifrost 2 -> Burson Soloist 3XP -> Hifiman HE-6SE v2. I ran into some financial challenges that required me to sell off most of the equipment (although I kept the BF2). Soon after, the forum start strictly enforcing a rule against non-PayPal sales in the classified section, which limited my ability to buy/sell used gear, thus any future new equipment purchases carried a lot more inherent risk. While re-building, I tried to stick to semi-affordable gear, especially things with options to tweak the sound. Aside from that, a lot of my time was focused on graduating, and then transitioning to new work after graduation, so not as much time for journalizing my headphone hobby.
Along the way, I picked up a Burson Funk amp, Chord Mojo 2, and then impulse bought an HE-1000 Stealth about six months ago after the price dropped to $1,400. I'd been content with those for awhile, until I decided finally scratch a curiosity itch with the V222 after noticing Drop still had some ready to ship units at $950.
Now, this is significant because I've held a long time bias against Violectric amps for many years because of some listening impressions I had at a meet maybe 7 or 8 years ago. My experience then (with the V200 using HD800) was that the amp was polite and inoffensive, but seemed to cover everything in this velvety softness, and it didn't seem as resolving and spacious as I hoped at it's price point.
That being said, my past experience with meet impressions has been problematic at best. Often times, gear that impressed me at meets (Beyer T1 many years ago , Focal Elear most recently) eventually soured on me when owning them over time. Conversely, some gear that I didn't find very engaging in a meet, ended up being among my favorite I've owned. (HD800 the first time, I've since bought it twice).
When I finally decided to pull the trigger on the V222, I was a little nervous, although Drop hasn't given me problems with returns in the past. I just wasn't sure if I was overhyping it in my mind based on a lot of the comparisons and impressions I've read. Thankfully, those concerns and my biases were completely unfounded. This thing rocks!
I received it earlier this week, and it's been quite an addictive listen. My experiences so far align with much I've read on the thread so far. I don't find it too warm and there's definitely nothing overly soft or wooly (at least in balanced mode). The bass.....yes, theres a perception of large and powerful bass, but what really caught me off guard was just how controlled and fast it is, while maintaining the quality and impact. I want to say this is a very rare trait in amps that aren't stratospherically priced, but there's also a lot of new amps I haven't heard and it's a more competitive market than ever.
The other thing that really surprised me is just how well it synergizes with the HD-650. I mean, I expected that based on what I read, but even that didn't prepare me. I've had my HD-650 for maybe 8 years or so, and when I got it, it was already well used. It's my long hauler that stays with me when times get tough. It's also been mutilated by modding (no rear spider, 2 adhesive sorbothane peices on each magnet. With the V222, the HD-650 takes on a strong sense control, impact, and effortlessness. Yes, it's still an HD-650, it's still warm some mid-bass congestion and no amp will change that, but I think this may be the best I've heard it on any equipment I've owned, although it's been a long time since I've owned my most expensive/high-end equipment. The HD-660S also sounds decent with it, but it doesn't seem to scale as well as the HD-650 in this case, perhaps due to the 150-ohm impedance instead of 300-ohm.
The HE-1000 Stealth also plays well with the V222, with the typical traits that have been covered: a touch of romantic harmonics in the midrange, deep and controlled bass, decent enough sense of space and soundstage (not closed in or claustrophobic by any means). As others have noted, there is a bit of extra perceived energy somewhere in the upper midrange. This is more noticeable with the HE-1000 Stealth. I think that this may be a combination of some of the tuning of the harmonics, and the powerful macrodynamic impact of this amp. I've never used software volume-leveling before, but I thought about it a few times with this. Some tracks that start with high intensity have actually startled me a bit (the dynamics, I mean). I don't find the upper-mids to be too much to be grating though.
Compared to the Burson Funk I've been using for awhile now, I expected this to maybe be a sidegrade with a different flavor, but it exceeds it in almost every way so far. I went back and forth a few times, and haven't had any desire to go back. My funk is upgraded with SparkoS op-amps and Supercharger (power supply) as well. That puts the total price close to the discounted V222. The Soloist 3XP might be a more fair comparison, but it's been over 2 years since I've owned it, and I didn't have the Supercharger with it. The Funk maybe has a little more air and sparkle in the highs, but I don't really miss it. The V222 is a more engaging listen across the board.
As far as sources, I've found that I lean more toward listening with the Mojo 2 rather than the Bifrost 2 with the V222. It was the opposite on the Funk, where I preferred the Bifrost slightly. The BF2 gives you a tiny bit more texture and sharpness on the leading edge of transients, but seems to hang onto sounds just a little bit long. The Mojo 2 seems more even handed and a little dryer, which works well with the V222s slight harmonic richness. It does make me wonder though, how the Qutest I once had would pair with it.
I also wouldn't mind trying the iFi Neo iDSD with it (or iDSD2 now I guess). I reviewed the original one awhile back, then bought it after to compare to the BF2 (using the Soloist 3XP) and then returned it. Back then, the BF2 just barely edged it out in comparison to the Neo iDSD and an RME ADI-2 (which was my current DAC at the time). I also tried an older iFi Zen DAC v2 I've had laying around for awhile, and while it didn't quite keep up with the Mojo 2 and BF2, I thought the iFi house sound was a pleasant tonal match with the V222.
Now...one minor complaint is that of the notched volume knob potentiometer, since it gives the drawbacks of a stepped attenuator without the benefits (aside from remembering a volume-level position). I think I understand the logic behind it, though. It does create the psychological effect of making it feel more premium, like you're dialing in a precision instrument. Maybe it's a German obsession with making things have satisfying tactility, like the deadened thunk of closing a luxury German car door. The other caveat is that it didn't quite have the same magic for me on the single-ended output. It's much softer and polite and a bit less macrodymamic, and lacks that iron-grip control that I find so engaging. In other words, probably closer to what my old memory of the V200 was, which makes sense.
Otherwise, Fried has nailed what I consider to be an ideal set of engineering compromises with the V222, giving us the excellent balanced output stage and high operating voltage while removing additional costs that may not deliver as much benefit relative to the added cost. Very well done.
That ended up being a little more wordy than I intended originally. Here's a photo of some of the gear to balance out the wall of text.
