Impressions:
First, a quick visual analysis: Both tubes seem “new” despite the GE being NOS, which is to say it’s perfectly clean inside. Up against a flashlight, the internal structures of the Genalex seems more complex than the GE. Another difference is that as soon as the amp is powered on with the GE tube, it lights up right away and is brighter than the Genalex. I’m also not a huge fan of the gold lion printed on the glass of the Genalex. Both have similar chrome tops. So, not that it matters, but looks slightly favor the GE. The gold pins on the Genalex are a nice touch, however.
Last night I had a chance to go to the SchiitrMeet where I quickly plugged some MrSpeakers Ethers into a Gungnir/Mjolnir stack to test out the Florence tracks that had underwhelmed me the night before. In short, they seemed up to stuff. So ya, maybe it’s not fair to compare $200 headphones with a $100 amp to $1500 speakers and more than $1000 worth of electronics (with dual subwoofers no less). But, in that spirit, I decided to start with some Florence and the Machine for my listening sessions again.
I picked “Big God” because I love that song and I didn’t listen to it in Part 1. Starting with the Genalex, I immediately thought it sounded pretty good. The bass went deep, had good definition and impact. Florence’s voice was clear and had good dimensionality. Switching to the GE, there were several changes. Within the first minute of the song, I thought that the soundstage was shallower. At around the 1 min mark, there is some echo in Florence’s voice that on the Genalex sounded like the echo in a room. On the GE, it sounded more like an echo affect that was flipped on digitally (which to be fair, is probably the case). At around 2:20 I thought the bass sounded stronger on the Genalex, and at 2:40 the music felt more lush. Being my first song, I decided to listen again on both tubes, and more or less confirmed these differences.
On to the the next song, the only repeat from Part 1, “100 Years”. GE was up first this time. I thought that at 0:45, the bass was a little lighter than I’m used too, though at 2:30 it hit harder. I felt that the song sounded a little thin overall, or that the soundstage wasn’t deep. Switching over the the Genalex pretty much fixed everything. Bass early on was better, and later in the song it was even more impactful and had more definition. The soundstage throughout also had more depth.
Honestly, I was already surprised by how big of a difference I was hearing, so I wanted to shake up the music a bit.
Next up was “Uh Huh” by Jade Bird. This is her debut album and man is it a lot of fun. Starting with the Genalex, I immediately noticed the build up of the drums in the beginning of the song. They start quiet but steadily get louder until they fully join in, so to speak. Jade’s voice came across strong with a good open sound. Bass also hit hard. At 1:35, I noted that the whole band felt very present in the song, more than I’m used to. Switching to the GE, I looked out for the same cues. The drums in the beginning were audible at the same time but had less texture, making their emergence less satisfying. Jade’s voice also sounded a little smaller. The whole soundstage shrunk a bit. The bass wasn’t bad per se, but it sounded a little more “one-note.” At 1:35 I felt I could hear all the same details, but the sounds were disembodied. I didn’t have the same sense of the band being in a room together.
I moved on to “Roaring 20s” by Panic! At The Disco. The chorus sounded less inspirational on the GE, and the harshest moments of the song (it’s not a great recording, to be sure) were a bit smoother on the Genalex. Probably most importantly, the Genalex made the background transients clearer, giving a greater sense of space. Put another way, it sounded like there was something physically beyond the instruments. On the GE, the instruments seemed to float in an empty vacuum. This made everything sound like it had less energy, as if the emptiness was sponging up the sound. That might be a bit too poetic for your taste but I think it accurately describes how I felt listening to the song on each tube.
I then listened to “Uncharted (Live)” by Sara Bareilles from her album Brave Enough: Live at the Variety Playhouse, which I adore, and “Aerodynamic” by Daft Punk. So something live with a piano and something electronic. I didn’t mine too much new info from these songs. The piano sounded more real on the Genalex, and the decay of the instruments was more natural. Meanwhile, the GE doubled down on its tendency to make bass beats sound like one note.
On “Some Nights (Intro)” by fun. (not to be confused with “Some NIghts”), the background noises were more recessed on the GE. Vocals and piano sounded duller, and the song was less engaging overall.
The conclusions were clear at this point, but the GE was in the socket, so I decided to run one more song.
Listening to “Say It” by Maggie Rogers (on another spectacular debut album), the Genalex helped incorporate the bass beat into the track, whereas the GE made it sound more like a thump in the background. In the opening sequence of the song the Genalex provided greater bloom to the music. At around 2:30 in the track, the air around Maggie’s voice is more open and spacious through the Genalex. She sounds more ethereal.
