First impressions time! Remember that these are first impressions from 1.5 hours of listening. I've heard so many amps that I can form reasonably cohesive first impressions according to my own baseline rather quickly. Extended listening will be required for a deeper analysis.
My immediate impression was: Wow is this thing clean! I've never owned an amplifier this clean before, and it struck me immediately.
Compared to almost every amp I've ever owned or even heard, this is incredibly resolving, detailed (micro and micro), and dynamic. It's really quite neutral. Some people might consider it a bit warm, but my amp experience has been pretty warm and I don't perceive it as at all warm. With the stock tube, it's a little crisper and brighter than I prefer for extended listening (I'm allergic to treble and love bass).
I swapped the stock tube for a 6N23P-EV after an hour because I tend to like those tubes and had one laying around (bigger bass than the Genalex. I was a little disappointed in the good-but-not-great slam of the LC until I swapped tubes).
The loop out makes A/B testing with the Eddie Current Super 7 fairly easy. I didn't volume match, just set the knob to my preferred listening volume for both.
Cavalli Liquid Crimson compared to almost every amp I've ever heard:
Cavalli Liquid Crimson compared to the Eddie Current Super 7 (with my mods and tube complement):
- A little bit more detailed
- Better blackground
- Cleaner
- More aggressive
- Brighter
- A bit thinner
- Slightly inferior timbre
- A bit dryer
- Soundstage not quite as deep
- Crisper
- Marginally less slam with the 6N23P-EV
From the bullet points, you might expect me to have a clear preference for the Super 7. Note that I have this paired with a Sonic Frontiers SFD-1 MKII SE+, which has marginally relaxed treble and nice slam. My headphones are the Sennheiser HD650 and JVC HA-DX2000, both noted for their slightly dark tilt as well as a bit of thickness to the sound. It complements my gear quite well.
I could rewrite the bullet points coming from the other direction.
And I will.
The Super 7 compared to the Liquid Crimson:
- A little less detailed
- Slightly grayer background
- A bit less clean
- More laid back
- Darker
- A bit thicker
- Slightly better timbre
- A bit wetter
- Soundstage is slightly deeper
- Smoother
- Marginally more slam
I have no idea which amplifier I prefer.
The cleanliness of the the Liquid Crimson is out of this world. It has an unbelievable blackground with a total void between notes. Inky blackness would be absolutely the wrong description--that implies there is something occupying the space between notes. The empty spaces in music are devoid of all matter. The Liquid Crimson presents music from an absolute vacuum.
It's very unlikely that I'll be able to convince my wife to let me keep both amplifiers for more than a couple of weeks. I've now spent retail on a Cavalli Liquid Crimson after getting scammed on one a few months back, and my Eddie Current Super 7 now has enough mods and tubes that it ought to be worth a fair bit more than I originally paid.
Since all I need to do to listen to either of the amps is flip the switch on, the ultimate test will be: Which amp do I use the most over the next week or two?
