I just got two units back and I'm happy with what they did. Originally the 2408 MKII I had modified wasn't compatible with my PC, it would crackle a lot. I called them up, they attempted to help me, they were nice and actually listened to me, but their suggestions weren't helping so they said I needed to send it back so as to fix the problem. They were going to send a return label to me, but I get really cheap shipping from my company so...a little off topic but the point is, they take care of you.
Of course, in a perfect world, I would get it back and everything would work perfectly and my recordings would sound like a million dollars. Black Lion Audio, from what it looks like, is a fairly new company and they are working out the kinks. I believe they are going to start selling their own stand-alone clock because I'm not the only one who has had compatability issues with PC (mac however works fine).
So now I have a 1224 and a 2408MKII analog only stages modified. It has only been two days, but the initial sound checks I've done are real positive. Working with the same equipment for close to 4 or 5 years you get used to what things generally sound like. When I recorded my voice, or acoustic guitar, or tambourine with an sm57 it sounded different than what I'm used to. Also, when using plug-in compression like waves compressors I could actually hear the subtle changes when adjusting attack and release at a ratio of 2.5:1, before I really couldn't hear much of a difference at all when I would tweek the compressor, and as a result would use a lot more compression.
The only other things I've noticed so far is noise level. There wasn't as much noise as what I'm used to. So I had to put on my headphones and crank it to see if there was much noise and there really wasn't. Usually there is something going on in that department. Also the bass seemed more "there" BUT and this is a big butt, I have only had this for two days. Things DO, though, sound different from what I'm normally used to.
So my listening environment is decent: HR824's and Sony 7506, and Beyerdynamic 770s. So I should be able to hear something. I haven't done anything extensive yet, but I did a simple recording of kick, snare, tambourine, two electric guitars, a bass, and 4 vocal parts for this school project and it was easier to get the sounds I wanted.
Anyways, girlfriend is buggin me, gotta run. I'll eventually post a little more soon...plus on the p.s. side I just gotta Lucid Genx6-96 from a fellow Gearslut so I'll see if that helps more.
