Greetings,
Wanted to introduce myself to the head-fi community. This is literally my first post to these forums. While I may be new to head-fi, I am no stranger to high-end audio and have been involved directly in the music software industry for many years. I am an engineer and a musician.
First off, I want to thank this dynamic community. The knowledge accumulated here is amazing. I've been very quietly benefiting from this group for a long time. It has served a great reference for me during those "difficult to reason through" purchase decisions. Not all of us have the time/means to travel around the world to audition the latest and greatest. But above all, I appreciate the honest and respectful community here. Thank you.
So it is time for me to give back just a tiny bit, and would like to relate my personal experience purchasing/owning a HeadTrip.
First off, I don't think writing up a review is particularly helpful (but I would be happy do so if there is a request). There is so much subjectivity here: differences in perception, differences in memory, differences in expectations, differences in the ability to even describe what we are hearing, and finally differences understanding/interpreting what someone else has written. That said, I am grateful to the reviewers of this particular amp, otherwise I would not have owned one.
Let me concentrate, instead, on what is not subjective.
I went through a 6 month evaluation process talking to different boutique manufacturers (EC, Wells, JPS Labs in particular). I did the due diligence by abusing the graciousness of my local audio-shop in SF (AudioVisionSF, a big shout out of thanks btw), and scheduled multiple, controlled, listening sessions where the only variable was A/B of amp to amp (modulo cabling at the store which was unavoidable). Nothing was "double blind" of course, but I tried to remove as much expectation-bias from the experience as I could (probably not possible). I focused on trying to find amp and headphone combinations that allowed me to "suspend belief" and just "drift into the music" (meaning: nothing in the presentation would jolt me out of the illusion). I quickly decided that the Abyss Phi CC was the right headphone for me (that is another story). However, I started at a place where I simply assumed that tubes were where I would end up. I moved up the great Woo lineup (WA22->WA5->WA33). By the time I reached the WA5 and WA33 I was convinced I was near my end-game. On a lark, I moved over to the Simaudio Neo340i. This was important for me, because the smoothness of the presentation from this SS amp completely randomized me - it meant tube amps were not essential to achieve that allusive musical warmth and general musicality. That said, for my tastes, the 340i was just a bit too smooth. I could have easily lived with it, but now, since my expectations were randomized, I figured I had more research to do.
At that point it was time to contact EC and Wells. EC has wonderful equipment, but they were not local to me, so I set up an audition with Jeff Wells. Just as before, I quickly moved up his line up (Milo Reference->Headtrip->Headtrip Reference(prototype)). While the DACs were different (Chord TT+Hugo2 previously, and now Denefrips Terminator), I was able still able to use the Abyss Phi. Finally, I was able to listen to my carefully ripped redbook content (as I did in SF as well).
Just as in the Woo lineup, there was a noticeable bump in sound quality/presentation. In relation to the Headtrip, the Milo was marginally less revealing, but was definately "warmer/darker" in a pleasant way. I could have lived with either unit. When I tried the Headtrip Reference prototype (the one with the clear front panel you've seen in all the show reports), there was another bump in resolution. Both the Headtrips had this silky (but not sibilant) high end that I find pleasing. Combine that with the extra power output and the Abyss's unique LF capability, I was stunned by the slam on the aggressive music I tend to listen to. Perhaps things were just a tad too dynamic and edgy for string passages ? Maybe, but I assumed I could correct that with a DAC and cables later on. When I moved over to trying Jeff's Lampizator it was obvious that I could.
So I was sold; however, I really did not want to pay for that truly beautiful case work used in the Headtrip Reference. Jeff had a solution, he said he could do a one-off build where he would drop in the Headtrip Reference electronics into a regular Headtrip case since I had one of the older cases in his workshop. I also asked him to make one custom modification: add an attenuator bypass switch so I had the option of using the attenuator from my preamp without going another set of resistors. Jeff was accomodating, I spoke with his tech just before the build and we sorted out how that should work. Finally, we negotiated a price for a unit which was significantly less than the reference, but a very fair bump above the regular Headtrip base.
Weeks later, to cut to the chase. I am truly happy with this amplifier & headphone combination. I obviously have not heard everything out there (and never will). In particular, I've never heard great stats yet (with their own amplifiers), so I cannot comment. My personal bias is toward a more micro-dynamic, forward sound such as you would get from a great pair of ATC speakers. This pairing gets me as close to that as I think is possible with current technology. The collaboration between JPS Labs and Wells Audio works.
Finally, I wish to address something that I've seen in some other wider reviews. For what ever reason, there is a certain background animosity that I've seen developed towards Wells Audio. I think this is unfair. I have no idea why that is, but I have seen former owners of the Headtrip, be literally "talked down" from owning it. Perhaps there really are better combinations out there, but I would say, trust your ears. Also, when doing research, you'll see quite a few people who've sold off their units (many on this thread). You might be tempted to interpret this as something is wrong here. It made me hesitant for sure. If I hadn't had the opportunity to actually listen, I probably would not gone down this path. This is unfortunate.
So this is why I am writing this. Jeff Wells produces an amp which is exquisately calibrated/tuned for use with the Abyss Phi. He is a pleasure to work with. He is accomodating about making modifications. His internal electronics layout is *exactly* as he posted in the previous message in this thread (e.g., clean). Yes, he maybe using controversial technology (bybee), but I do not care. If you buy this amp, you are really paying his ears in effect. His sense of aesthetic. This aesthetic just happens to match mine very well. Your ears are obviously different
Finally, I realize I'm a complete newbee in this community. If you are reading, why would you listen ? Well, I'm hoping I've touched on enough of the objective parts of my experience over the last few months to lend just a bit of credibility. I'm also not hiding behind an alias
My experience with the Abyss+Headtrip has been that positive to risk the spam and the hate (lets hope not). I have absolutely no connection to Wells Audio other than I spent 8 hours auditioning his equipment locally.
All the best. Please PM me if you have any questions.
