Amp recommendations for Audeze LCD-2 - Page 410

post #6136 of 7692

Yep. Not to mention the VI+ has more than enough power to drive the HE-6 or K1000, two of the most difficult headphones to drive. 

post #6137 of 7692

Yeah I was really amazed by the high current ouput, makes me think of the SS amps from Audio-gd.

post #6138 of 7692

By the way, given that the amp is OTL/OCL, how does its output impedance measure? I've only read that people like using the LCD-2 with it but nothing about its pairing with lower impedance headphones. Waiting for Davidzhezhe's response as well.

Just out of curiosity, how many hours does a tube usually last?

post #6140 of 7692

5000ish hours. Depends on the tube of course.

post #6141 of 7692

what about vintage or NOS tubes?

post #6142 of 7692

Just got a reply from David.

 

He writes that the power output into 50 ohms is around 6W per channel and 3W per channel to 600 ohms. The balanced output impedance is 32-600 ohms. (The impedance description he gave is very standard and not that specific, so it's hard to pinpoint its exact value. The same spec was given for the MKIII which has a fairly high output impedance and did not work that well with low impedance headphones.)

 

While the output power is really amazing on the MK6, especially for orthos, the output impedance is a little discouraging even though it is expected of a tube amp which is not transformer coupled; damping factor might not be that good with low impedance headphones, so I'm a bit concerned with how it fares with the LCD-2 in regards to damping factor.

Orthos drivers are purely resistive load, generally not affected by (electrical) damping (that much) if that's what you're worried about.

Okay, I see, thanks.

post #6145 of 7692

From what I know, frequency response will not be affected by output impedance but damping will.

post #6146 of 7692

Yeah, but I usually think of damping factor being higher with lower ouput impedances.

For solid state, I'm going to say Mjonir, b22 or possibly even the Soloist (as others like it) as near end game for the LCD2's at the up to $1k price range. If you change your mind about spending too much on just an amp and want a little remaining for a DAC. Any of the Violectric stuff (V100/200) fits this bill pretty easily as they go for around $750-800.

 

Although you find this as interest, I've got my modded LCD2's hooked up to a $60 Marantz PM-32 integrated amp with bass/treble dials and I can tell you, in terms of sound this thing puts out I like it more than any of the solid state amp's I've owned (V100/V200, b22)

I just recently decided to go all in with LCD2.2's and they arrived yesterday! i don't have an amp or DAC yet, so I plugged them stock into my denon 3313 receiver to see what I'm going to be working with.

 

I'm considering between the lyr/bifrost combo or burson HA-160D for starters. If you can suggest something better, I'm all for it. My budget for an amp and dac right now is around $1000 total. I'd like to list some pros and cons on the LCD2.2's (stock) so you can steer me in the right direction.

 

Pros: Transparent, musical, dark sound signature. I like the coloration in mids and especially bass, since I am more of a basshead. The music feels *alive* as opposed

          to neutral, dry, grainy or too analytical.

 

Cons: Lack of clarity in treble and mids, especially with electric guitar. Sound becomes muddy with more volume. I like to listen at high volume and know I can't without a good amp.      

          Soundstage is a bit more closed than I expected.

 

If I could have an amp that enhances the pros and helps strengthen the weaknesses (clarifies the muddiness, allows high volume listening, opens up the soundstage, maintains the musicality and the sweet mids and bass), I'll be set. With a $1000 budget, I'm not expecting perfection, just the best value for my preferences. I listen to most if not all genres, but more than anything rock/metal/alternative. Thanks in advance!

 

 

Upon further research, I've decided I'm going to spend a little more money on an amp so I hopefully won't have to upgrade. The three names that keep coming up are Mjolnir, Soloist, and V200, as well as in DefQon's response. Out of these, what do they offer compared to one another, and which would be the best for my preferences?

Depends on the grade of the tube. How many hours of listening time/how long you leave the amp on/the tubes being NOS or completely brand reissues. It's good to buy spares as well.

Yeah around this mark.

Personally for myself, I greatly prefer the VI+ out of the amps mentioned. There's not much of a con you can find with the VI+ unless you compare it directly to the > $2.5k flagship bad boys such as the higher up Cavalli amps, Leben CS300, the Eddie Current line up etc, then you notice very little subtle improvements here and there which for some people can make a minor to big difference.

 

I also like my other dynamic headphones powered off the VI+ as well. 

 

Just remember that the amp may cost less than $1k, once you start tube rolling, you will exceed $1k very very easily, but at the same time is very very rewarding.

post #6149 of 7692

Did you like the Hd800 with the VI also? just curious =p

post #6150 of 7692

I like it but it's not the best pairing with the HD800 I have ever heard. There is the VIII SE that David designed solely for the high impedence Sennheisers (580-800) which costs a little more due to some of the parts used. I haven't heard that amp so I cannot comment how well it performs with it.
