Tried the LCD x today at a high end speaker store. Man i wanted to cry, never heard such beauty. even for older progressive metal albums. Unfortunately didn't get to try the lcd 2 with a higher end amp, but did try them with the Chord Dave. Still a no go. Thinking of picking up Audeze Decard to power the LCD 2 that i got from the b-stock sale... Hoping i can come somewhat close to the lcd x sound.
Okay, So I just got back from the store not long ago. I have to say I did learn a lot this time around. (Keep in mind, I have good ears, but I'm still pretty new to hi-fi audio. So take my experience with a grain of salt and see if you can compare these on your own).
Deckard vs O2 (just the amp) with LCD-2f:
First, I tried their LCD-2f with their Deckard + Sony HDD combo (FLAC files). It sounded spectacular. Compared to my O2 amp connected to my PC at home, there was only a few differences. But there was one big one that really made the Deckard my amp goal.
The vocals still came from above me, so that might just be in my head since I'm not hearing anyone else have this issue. Secondly, the sound itself wasn't too much more crisp than my home setup. But the mids and treble felt a little more detailed and separated. Not enough to spend $700 on an amp, but enough so that it was clearly noticeable to me. However, the bass had more body to it, and thus filled the cracks in the music much better. In my home set up I fixed this with a bit of EQ. But with the Deckard I wouldn't need to touch the EQ to my liking.
The biggest difference by far was the fact that on my O2 amp, I have to put the volume slightly higher than I want it, to really feel the details of the notes (60% PC volume, 60-70% Amp volume), and to separate every instrument. On the Deckard, I had the volume just right (about 30-40%), and it sounded perfectly detailed. Then when I lowered the volume, it felt just as detailed as the higher volume. Put simply; the music felt effortless (which greatly increased the sound-stage to me personally). The music flowed through my headphones like water. It was really great. My O2, though doing it's best for me, feels like it's struggling now, though it has more than enough power for these headphones.
I can't say if it's the Sony HDD, or the Deckard that was making the biggest difference, but since i'm playing FLAC files on my PC anyways, I'm pretty sure the Deckard was the culprit.
Overall, I think the Deckard is completely worth it for the sound I was hearing. I will be saving up for one in the future (Maybe a used or demo version lol). However, if the O2 sound suites you fine. I don't see the immediate need to upgrade. I'll be happy with O2 until I slowly save up for a Deckard.
LCD-X vs LCD-2f:
I tried comparing the LCD-X with the LCD-2f. The sound was clearly within the same family, but it had its own distinct flavor. On the LCD-X, the highs were slightly more detailed, the mid were marginally more prominent, and the bass was just about the same (maybe a little tighter, but I like the way the LCD-2 bass wraps around me). Overall, with the Deckard set up, the LCD-X were about 10-15% better overall than the LCD-2f. Personally I wouldn't spend double for that difference. Especially when the sound that the LCD-2f with this amp give, is already spectacular.
LCD-3 comparison:
I tried comparing the LCD-2f and X with the LCD-3. There is a noticeable improvement. But I would say it's about the same as the last comparison. The sound stage got about 5-10% bigger too with each model. Enough to notice, personally not enough to justify the cost.
LCD-2f with Shiit Lyr 2:
No thank you...
More detail; The distortion added just didn't sound good with the LCD-2f. The bass was distorted and the mids and highs mashed together. Still had the Audeze sound, but as if I was playing a very low quality file. The Lyr may be a great amp, but when I went back to the Deckard, the clarity of the music was much more enjoyable for me. Personally, the Lyr 2 is a no go for the LCD series.
My own LCD-2f aluminum vs Demo LCD-2f rosewood:
Pretty much identical. My headphones sounded a bit clearer since the stores ear-pads were squished due to the stands they use, which made the bass a tiny bit muddy. Their headphones probably have more burn in time than mine too. But overall I preferred mine (they had a better seal on the ear-pads).
I also tried their He-500s that were on display. They were also nice, and very different. But that's not for this thread lol.
Hope this helps!! Feel free to ask any questions while this is fresh in my mind.
