Amp recommendations for Audeze LCD-2 - Page 498

post #7456 of 7727
Can someone offer their experience with the following 2 tube amps for my lcd-2 v.2.
Little Dot mk6+ and Bottlehead S.E.X. 2.1 with C4S mod.
I'm looking at going back to tube amp. Had the Mjolner but didn't like the sound. The sound is fatiguing after a while. I like the sound of Woo Audio WA6 but just wish it had more power and better sound stage.
Help me decide which amp to buy.

I do like the NFB-28, which is incredible for the price, and the  Mjolnir/Concero. With that being said, I don't know if I would go with them just because they only goes down to 20hz. I'd like to get a setup that goes down lower but I am finding the price jumps up the lower you go. I know I can't exactly hear much at 5hz but I sure can feel it. I saw a couple setups that go down that low but they are expensive. I am thinking that is the trend or am I wrong?

Now there's new Lyr 2.  More neutral I heard.  Might be even better match with LCD-2

I am only going off what they list on the sites. They might be able to go down lower but they don't list it?

The Lyr 2 is listed at 20 HZ - 20 KHZ + or - 0.1 DB, which means it is flat in the audible spectrum, it provides power/current across to your HP, with virtually no change to the signal across the audio spectrum, you are misunderstanding this value.

Ohm I wasn't talking about Lyr 2. I don't want to use a tube amp though. Sorry for the confusion.

Wildcats' observation is correct in general though, not just for Lyr2. Manufacturers (when they state a range at all) do so with a given dB tolerance like Wildcats mentioned. It doesn't mean there isn't usable energy outside the range. IIRC my power amp is 0.5 dB down at 5Hz, for example...

Dropping by to attest to the wonderful synergy with the Audio-gd Precision 1 headphone/speaker amp in high gain mode.  

 

From another thread:

"If I had to sum it up in one word, the LCD 2 + Precision 1s combo = natural.  It's a balanced, neutral and superbly well articulated sound - liquid without losing clarity.  The bass is full and textural.  The mids and vocals are present without being in your face about it.  The treble is precise and never harsh.  There's a here-ness to the presentation, the music envelopes and engages you and keeps you in suspension of belief because everything is really real."

Love how my lcd 2 sounds with pan am and passport, compare to my SS amp the music is more alive

The reason everything is specd 20 to 20 is because that is the standard.  CD players generally go a lot lower, and nearly all amps.  The 20 hz standard is to allow for techniques to block out DC.  This is normally accomplished in the first 2 hertz.  Look at a spectrum analyser and you will find a significant proportion of most recordings from many genres indicate activity well below 20 hz all the time.  Whether your transducer can create this or whether you can hear this is debatable.

That is good to know thanks for the information. I am using the O2 right now and it doesn't list a sub 20hz on the specs page but I can still hear 10hz. I am using http://www.audiocheck.net/soundtests_headphones.php to hear the different levels. Granted I don't know how much + or - I am getting at that level but I can still hear it. 

 

On another note, I chose the b22. I'll have my hands full on reading and picking out parts in the next couple months but it sounds like fun.

That's correct, though this standard is an approximation chosen for round numbers. Actual human hearing range is shifted slightly lower. Most people can hear below 20 Hz though very few can hear 20 kHz or higher. That said, many of the audible differences between headphones and amps are well within the audible spectrum. Differenting A from B is more about the brain than the ears. Your ears are already picking up some of the differences, but your brain is ignoring them so you don't "hear" them. Listener training makes a big difference.

Long-time LCD-2 owner here (version 1).  7500 posts into this thread and I'm going back to page 1 from Skylab.  Just picked up a used Leben CS300.  All I have to say is: Oh sweet lord, the music!

 

I've played the LCD-2 through a bunch of headphone amps, including a balanced Cavalli EHHA (strong tight sound, very precise) and recently from the headphone out on my Benchmark-2 Dac (very clinical, a touch fatiguing).  The temptation with the LCD-2 is to want to analyze the music.

 

Now listening to the Benchmark feeding the Leben and with great performances all I hear is music. All the detail is there, but instead of hearing how separate and distinct all the instruments are, I hear how they all fit together and how great the musical phrasing is.

 

A few highlights:

 

Skip, Hop, and Wobble (by Jerry Douglas, Russ Barenberg, & Edgar Meyer) - one of my all-time favorite recordings by 3 of the greatest studio musicians out there.  Gorgeous, tasty phrasing all day. You can see the three of them sitting there jamming

 

Let It Bleed (Rolling Stones) - layers and layers of sound. The groove is completely infectious

 

Live at Ronnie Scott's (Jeff Beck) - wow. Sitting in the front row for this incredible ensemble performance

 

A Love Supreme (John Coltrane) - always loved this performance, but holy crap! Pushed play on this and didn't notice anything else for the next 35 minutes

 

The First Time (Roberta Flack) - one of the best written songs ever. Put the LCD-2's on my wife to listen to this and she just closed her eyes and smiled for the whole song

 

 

 

So, thanks Skylab. Short of some tube rolling, I'm not going to touch a thing with this setup.  Just sit and listen to great music.  Who needs sleep anyway.

Thanks for the excellent review and recommendation! I have always read nothing but great things about the Leben amps. I am still backing my horse the Sophia Electric Baby. It outperforms everything I have compared it to. It puts  me in the same space as your Leben for exactly the same reason. Of course it requires a voltage divider network on the output as the 10watts is too much straight out for my Audeze LCD2.
