aerius Posted October 13, 2007 Report Posted October 13, 2007 The impressions will come late tonight or sometime tomorrow after I get around to listening to it in a short while. I'm over at Roam's place and we just finished de-fucking one of my tube amps.
deepak Posted October 13, 2007 Report Posted October 13, 2007 Woah /neo if you can post impressions of his OBX-R2 that would be cool too.
JBLoudG20 Posted October 13, 2007 Report Posted October 13, 2007 Postjack also enjoys defucking phallic symbols.

aerius Posted October 14, 2007 Author Report Posted October 14, 2007 if you can post impressions of his OBX-R2 that would be cool too. I could, but I don't know how much that'll help considering that his pair is not anywhere close to stock, and it's also been retuned for a more neutral balance with a new x-over box he built. Basically, it sounds like a Quad ESL-57 with more bass, more dynamics, a bigger soundstage, and a much bigger sweet spot. The '57 has sweet spot that's about as wide as your head. Anyways, the Moona Moona Luna. Setup was Capitole to XLO Sig2 cables to Luna (Mullard E88CC & stock outputs) to modded HP-2, RS-1, and K340(mine). His amp is the base model, except he swapped out the input transformers for the amorphous core version from Lundahl. I did most of the listening with the HP-2. The amp looks kinda cheap & plain, but it sounds damn good. It's a better match for the HP-2 than the RS-1, the slightly warm balance helps to keep the HP-2 from sounding to analytical, but with the RS-1 the mid-bass hump gets a little out of hand and it loses some resolution in that area. Other than that there's really nothing I can complain about, it just does everything well, no sibilance, no mushy slow bloaty crap, no overly rich midrange, no roll-offs in the highs or lows, or any of that other crap I've heard too much of in tube amps these days. The first thing I wanted to do was check out how much resolution it had, so I threw on Sarah Slean's "Sweet Ones" to see how deeply I could hear into the multi-tracked vocal parts. It was pretty good, I could tell that each track of the multi-track had some reverb & chorus effects of its own before getting made into the multi-track, but it wasn't able to resolve the echo-chorused multi-tracked multi-track vocals near the end of the song. Still pretty impressive performance as only a very small handful of amps can manage the first part. The smoothness & coherence test was the Transmission album by The Tea Party, specifically, the title track, Psychopomp, and Pulse. Psychopomp is fun since it's a real busy track which goes from a few instruments at the start to lots of stuff playing real loud. The Luna keeps everything nice & separate, the quieter instruments don't get drowned out and lost when all the electric guitars & mad drumming kick in. Cymbals are crisp & clear without getting harsh, drums are good & dynamic, and Jeff Martin's vocals sound right too. Transmission is more of the same except with a different mix of instruments & effects, no problems here either. Inferior amps will round off the cymbals and become discombobulated & lost when things get loud & busy, instruments get lost altogether, the soundstage becomes a mess, and the amp will sound constipated. Played From Hunting Ground To City by the Cowboy Junkies to see if it would mush up a warm recording, and also to see if I could hear all the electric guitar goofs. There's a few places where the guitar goes into a bit of a feedback squeel, I don't know if they meant to do that but it sounds kinda cool and has a nice tube tone since they used tube amps and recorded the whole album with vintage analog gear. It sounds right, the guitar tone is just about right, it does indeed sound like a Fender and Margo's voice is damn sexy. Margo really knows how to work it, she's got that sultry smoky thing nailed down and it comes through perfectly. Skipping a few tracks to "He will call you baby", but this time with the RS-1 and it was more vocal goodness, lots of emotion and it was just haunting, by the end of the song I was like "damn..." That doesn't happen often these days. While I was on the RS-1, I played some G n' R to see if it could rock, I gave it a good dose of "Sweet Child O' Mine" and "Paradise City" with the volume cranked up a bit, ok, more than a bit. It rocks, no problem at all, Slash's solo in "Sweet Child" was damn sweet, the tone's right, the dynamics are good, everything ticks. There was a bunch more music I played, but I ended off the session with more Cowboy Junkies, the Trinity Sessions album since I wanted to do the cymbal tone & decay check and since it's cool to hear sounds bounce off the walls of the church, that is, if the system is good enough. It is. Dreaming My Dreams is cool since there's a solo part in the middle where the cymbal gets hit every second or two, each hit sounds different since the cymbal moves and the drumstick never hits the exact same spot, and you can hear the decays & echoes. The Luna does make each hit sound unique, most amps make it sound like a loop of 4-5 hits, in the latter case low-level detail is being lost. Decays are good too, they sound real and trail off a long time as they should, and the wall bounce is there with the drums, vocals, foot taps and cymbals. All in all, one of the best amps I've heard. It doesn't have the resolution, technicolor vivid tones, and realism of a DHT tube amp, but among IDHT amps it's in the upper tier for sure. Pure stealth amp, looks plain, but killer sound. It's neutral and has the naturalness of tube sound, and from what he tells me it just ends up sounding like whichever input tupe you stick in it.
fierce_freak Posted October 14, 2007 Report Posted October 14, 2007 Cool, thanks for the impressions, aerius.
Nanoha Posted October 14, 2007 Report Posted October 14, 2007 Yes, the Luna is my favorite sounding headphone amplifier that I've heard by a longshot though I had only spent a little less than a hour with it.
boomana Posted October 14, 2007 Report Posted October 14, 2007 Nice impressions. Now, of course, I want to hear one for myself.
deepak Posted October 14, 2007 Report Posted October 14, 2007 God damnit I want to hear those speakers, but I won't be near a dealer for another 2 months :'( edit: was he using his DIY Wavelength amps with the speakers? And since it sounds like you listened to a lot of rock with the Luna I assume you did with the Living Voice as well?
aerius Posted October 14, 2007 Author Report Posted October 14, 2007 God damnit I want to hear those speakers, but I won't be near a dealer for another 2 months :'( My Living Voice dealer is about 30 minutes away. I thought I should mention that again. edit: was he using his DIY Wavelength amps with the speakers? And since it sounds like you listened to a lot of rock with the Luna I assume you did with the Living Voice as well? Nope, those are for his K1000 headphones. He uses a variation of the Aurora with a DHT input tube and transformer coupling on the front end. The tubes were 26, 45, 300B, and the transformer between the 26 & 45 is a stepup transformer. His other amps are much cooler though, high voltage transistor amps running at 150V-200V with output transformers. Puts out about 30W, almost as good as his all DHT amps according to him. To me they sounded pretty much the same. Even more cool is his large open baffle speakers, still being fine-tuned. Large Heil tweeter, Lowther wideband driver, and 3 12" Eighteen Sound woofers for the bass & mid-bass. Looks kinda like the old Apogee speakers, but with dynamic drivers & the Heil tweeter. Efficiency is something like 98dB/W/1M, but it can handle several hundred watts of power. The OBX-R's will compress if you push them above 100dB or so while the prototype speakers can hit 115-120dB before running into trouble. Much bigger dynamics, and can play way louder.
deepak Posted October 14, 2007 Report Posted October 14, 2007 My Living Voice dealer is about 30 minutes away. I thought I should mention that again. I should have ditched my group for a few hours when I was in Niagara Does that dealer demo the speakers with the Kondo gear that Living Voice recommends?
philodox Posted October 16, 2007 Report Posted October 16, 2007 Told ya it was good. I'd love to compare the Luna to my amp now, as it is really hard to do a comparison based on impressions from two years ago. You need to get to the next meet I have at my place Aerius, it is sounding a LOT better than when you heard it last... and it is pretty now, which helps.
NotoriousBIG_PJ Posted October 16, 2007 Report Posted October 16, 2007 Thanks for impressions. Must resist urge to hear dht goodness... Biggie.
aerius Posted October 16, 2007 Author Report Posted October 16, 2007 Speaking of DHT's, full Artemis Labs setup, featuring a nice SET 300B amp. Let me know if you wanna hook up there.
philodox Posted October 16, 2007 Report Posted October 16, 2007 Why don't you use that wicked avatar over here?
aerius Posted October 16, 2007 Author Report Posted October 16, 2007 Because if I did, I'd get confused as to which forum I'm on, and that would be very discombobulating. I think I'm going on Tuesday, you know where the store is.
philodox Posted October 17, 2007 Report Posted October 17, 2007 I'm tempted, but the last time was almost too much... I prefer to just enjoy my meager rig.

aerius Posted October 17, 2007 Author Report Posted October 17, 2007 How easy is it to get there from union station? Biggie. Dead easy. Take the subway to St. Clair West station and it's less than a 5 minute walk from there. webpage with maps
HiWire Posted December 28, 2007 Report Posted December 28, 2007 I just read this. Fantastic review, aerius.
