ECP 3F Ravenswood (my sad attempt at trying to capture the beauty of this LOL) Aesthetic/ non-sonic related: I chose Bocote for my choice of wood and amorphous for the transformer option. IMO Verite already had plenty of body and warmth, so I thought the amorphous was the better option (for me at least). When I saw @atomicbob ’s spalted-maple 3F, I wanted to find the wood that was just as unique-looking, exotic (but NOT endangered) wood. After a couple email exchange with Doug, I ended up with Bocote, with its tonal contrast to the silver body and unique grain pattern. I originally wanted Ziricote to match my Ziricote Verite, but the upcharge was a bit much. Suffice to say, Doug did a wonderful job creating a beautiful piece of hardware that looks just as beautiful as it sounds. I first found out about Ravenswood/3F through SBAF back when I was a lurker. Seeing Marv and other friends speak of this amp with such high praise, I became curious about this amp. I’ve never heard of ECP and the price tag initially threw me off a bit, but I decided to take a leap of faith and do a blind purchase. I did a similar thing before with ZDS and I was quite happy with the sound. I still regard that amp as one of my favorite tube amp and reference quality for stage width and depth. It took me a while to save up for this amp, but when there’s a will, there’s a way Throughout the waiting period, I’ve had my moments of doubt, but after talking to many of the members who have heard the 3F, (@jexby @Gaspasser @Phantaminum ) all reassured me that I would be getting a real solid piece of gear. Aaaaaand yep, they were absolutely correct. This is a spectacular headphone amp. I never thought I would write such a positive review about a solid state amp since I’ve always preferred tubes, but here I am. Listening chain: Eitr > Gungnir Multibit A1 > ECP 3F Ravenswood > Verite + Verite pads | Auteur + AL pads | Elex | JAR600 General impressions: Something I noticed immediately was how good the dynamics (both micro and macro) were. The bass on the 3F is robust, fast/snappy, full of energy, and renders bass with some cajones. Bass doesn’t sound one note and quite multi-layered. The 3F allows the headphones to operate at full potential in terms of transients and slam. I didn’t think ZDT Jr’s bass was that bad until I heard the Verite+3F. It’s made me want to listen to EDM again. vocals and instruments sound textured and effortless. Instruments are well separated and really easy to pick apart complex music. Images just pop out of nowhere and you can see images float around. I thought the imaging on the Verite was one of its weak points given its price tag, but with the 3F it was no longer an issue. Like others, I noticed that I listen to 3F a bit louder than usual, but without a hint of fatigue. Excellent clarity and presence: treble is well extended without timbre issues or sharpness. lively sounding and really grips the music. Slightly reduces the rough edges while maintaining the energetic nature of the headphones. The slight sense of hollowness in the Verite is ameliorated by 3F. Wide sphere of sound, but lacks a bit in depth compared to TOTL tubes. I think amps like ZDS and Starlett will pull ahead in this category. However, I wouldn’t worry too much about this as the amp still holds its own very well and is not a flat wide pancake-stage like Jotunheim. Pairing Notes: Auteur+ 3F: If you’ve read my Auteur review, you know I much I liked the synergy with this. Synergy that made me think of selling the Verite for an Auteur. Really lets the biocellulose bass shine, with the right amount of presence, clarity, dynamics without a hint of sharpness/sibilance. Verite+ 3F: Another synergistic pairing. Slightly less.. I mean by a hair less than Auteur, but still an excellent match. Verite’s inherent qualities to throw 3D, life-like stage, zippy transient, and resolve are realized with 3F’s pinpoint imaging capabilities and sense of immediacy. It doesn’t feel like I’m listening to a solid state amp. Elex + 3F: As this amp was originally intended for Focal headphones, I wanted to at least try it. As expected, great synergy. The Elex is a bit tipped up and bright for me, but with the 3F, it slightly reduces that edge while maintaining the liveliness. This pairing didn’t get a lot of head time since the synergy was far greater on both Auteur and Verite. I don’t know, maybe Nickel transformer would have been a better match or I guess it just didn’t capture some of the emotions I’ve felt with ZMFs. Still highly recommended if you’re into the Focal sound. JAR600 + 3F: Actually scales quite a bit with the 3F, but now I can kind of understand why @ColtMrFire preferred his T3 over the 3F. At Least with the JAR600, while I was able to hear and appreciate the technical prowess of the amp, but it was a bit too dynamic and borderline-shouty at times. I’ve never heard the T3, but with the JAR600, I would pick the ZDT Jr. over the 3F purely in terms of synergy. I think this just shows how important synergy is no matter how great the gear is. Closing thoughts: I feel like recently my impressions have been a bit too positive, at least in the last few impressions, but I have to give credit where credit is due. Like others have previously stated, it’s a fantastic sounding solid state amp with robust, tactile bass, excellent sense of dynamism and immediacy. While it doesn’t completely negate all the drawbacks of solid states such as expansive sense of stage depth, it still holds its own in terms of sheer technicalities and emotional involvement. One thing to be aware of for future/potential owners is no matter how great the 3F is to make sure to feed it with a headphone with the right synergy such as ZMF and Focal. I personally would not pair it with the HD600/JAR600. The synergy with the Auteur and Verite was noticeably better (at least for me) compared to Elex and JAR600. Anyways, I hope more people get to hear this amp, because it surprised the heck out of me. I never thought I would enjoy a solid state amp this much. I only have the 3F+ Verite/Auteur to blame for all the late nights of musical enjoyment.
