I have found brightening things up with tubes helped with the HD-650's, but the LCD's are just sounding dull all around. Nothing pops out at all, and I'm used to listening to laid-back headphones (they're my preference to begin with... I really hate the newer bright headphones, that's why I upgraded from the 650's to the LCD-3F's). Like I said, I tried Siemens grey CCa's, Telefunken E188CC and CCa's, Philips pinched waist 6922's, etc... these tubes really shine with the 650's, but I find them all to sound rather lackluster with the WA2 and LCD's. The Telefunken's did sound superb, but very neutral. Jazz is great, but rock/acoustic not so much. (The funny thing is the LCD's actually sound rather good with a Telefunken tube straight out of the T1 as well...)


The WA2 pumps out 310mw @ 32ohms. Very under powered for the LCD3 which states it needs 1W @ 32ohms. The WA2 is not even supplying 1/3 of what is needed. :eek:

 

I was looking at the WA2 way back and avoided it for this exact reason. I ended up with the WA22 which produces 1500mw (1.5W) @ 32ohms.

 

Boy does it make the LCD3's sing. I also have the Oppo HA-1 SS amp. The WA22 kills it.

Thanks @Badas - That would explain what I'm hearing. I thought the nominal impedance was higher with the Fazor rev? 110 ohms or something? Either way, I will wait for the Liquid Carbon and see how it fairs... it advertises 1.5W into 50 ohms. I'm sure I'll have to go with a WA22 in the future... gah, different driver/rectifier tubes. Great.

I agree with badas. I thought the WA2 might be underpowered but couldn't remember for sure.

And indeed, 3F is 110 ohms. 3C is 45 ohms.

No way the 3F is dull!

But today I got home from work with a new Hegel HD25 DAC to test and wouldn't you believe it, the right drivers had failed, and no sound coming from the right. After som bad language and adjusting the cables, switching between left and right to confirm it indeed was driver failure, the left side went silent!!
I am on my way to fill out the RMA form. And since I live in Norway I am guessing a month of waiting, like the last time.

I feel your pain man, I bought my LCD3's only to have them arrive DOA ( bent frame issue) then only 5 months later right hand side driver failed ( exactly as you described for yours) took over 6 weeks from me sending them away to them arriving back in my hands.

I was absolutely livid when it happened pretty much tore the sales Man a new one because I knew it would be a long wait ( I expected a month) and it took even longer.

I am a little nervous as everytime it happens I have to pay the shipping and wait another 4-8 weeks

Audeze does indeed say it needs 1W @ 32 ohms , but the reality is different IMHO (especially as the newer headphones have different sensitivity as well as impedance). There are plenty of amplifiers that drive it well enough. Look at this chart here

 

http://linustechtips.com/main/topic/221772-calculating-audeze-lcd-2s-power-requirement-vs-o2/

 

It talks about LCD-2 but the basic principles are the same, as just as the LCD-2 has had a couple of iterations of sensitivity changes, so has the LCD-3 had a significant change.

 

You will notice with the original LCD 2 that approx. 700mw is required to hit 120dB of dynamic range. 120dB of dynamic  range is a bit of a dangerous listening level if there are regular peaks at that point. It could cause hearing damage!

 

However, you do want to be within the optimum operational range of an amplifier so having some headroom is a good idea. Having said that I found the LCD-3c worked just fine on the Sony PHA-3 amplifier in balanced mode which is 320mW per channel.

Thanks for the info. What I'm hearing is plenty of volume, but to me, they are sounding dull/overly polite. Nothing seems to be sounding as good as I have heard in the past from the LCD 2.2, or the HE-500. They sound to me how the HD-650's sounded being driven by less capable amps... just overly dull. 

 

I actually do the majority of my listening at a volume that probably wouldn't be considered loud, so louder volume really isn't a concern for me. I'm going to try some other gear with them at a meet next month, so I'll see how it goes. I'll probably wait for the Cavalli Liquid Carbon myself...

Indeed but I must say Audeze's customer support is excellent! But living outside of the U.S. makes it a hassle with shipping and the time it takes to get them fixed. But since the retailer where I bought it takes forever just answering an e-mail I rather deal directly with Audeze with these type of issues.

Last time it happened just before I was about to leave on a three weeks vacation. No vacation ahead this time though :(
