I like the synergy of the EF-5 with the HE-500 leaps and bounds above the O2. Change the OPA and upgrade the tube and the EF-5 is on par with much more expensive amps (stock it sounds good as well).

I only used the Ef-5 with the He-500 and it gave warmth and a very musical sound. It sounded a lot better to my ears than the JDS Labs O2. But now I got the Emotiva Mini xa100 speaker amp that im using the He-500 on, and it sounds beautiful!

 

EDIT: Also, the Stock on the Ef-5 sounds very musical and pleasing., as for the Lyr I've read a few times that the Stock tube is garbage...

EF-5 sounds beautiful with the HE-500s..

 

Had the Bifrost + EF-5 -->HE-500 for a while before i upgraded to the Lyr.

 

Both Lyr and EF-5 have their strengths that both make them fantastic amps in their own regard.

Don't have the HE-500's but I do have the LCD 2.2's and so far all I can say is wow! I feel like I'm finally starting to get the full Ortho experience now that I have the right amp to push them. I have a feeling the EF5 was made for the HE-500's so it's worth the extra cash to get that instead of the O2/ODAC combo which of course by all means is a fantastic amp.

For the money you may also want to look into a Matrix M-Stage. Class A amp with clean detail and power to spare.

Just doin my part to add confusion and doubt to the mix.


Thanks,

I'm choosing between these amps also, what are the strengths driving HE-500's??

From personal experience.

 

Lyr = more power, sounds 'stronger'

 

EF-5 = more warmth and more synergy.

 

Both are good but I find the EF-5 makes the HE-500 sound smoother.

That sounds like a better version of the smoothness I'm getting from my TD-11 SS out. I need more power though it starts breaking up a 3 o'clock, it's only 600mw @ 32ohm. The EF-5 I understand has 2w @ 32ohm so that should put me back at 12 o'clock for semi high volume listening? It's half the size of the Lyr and 1/10 of the mini-x I was starting to consider until I saw the size of that monster as a desktop amp "WOW" no thank you😳

Also have you tried the 627 opamp? Which tube are you using?
Thanks in advance

You can't say much about how loud you'll turn up the potentiometer based on ouput power. It depends on a lot of factors, really. I am considering the upa-200, lolz. That one is BIG.

I don't have the EF-5 anymore as I kept the Lyr.

 

The EF-5 had more than enough power for the HE-500s IMO. I just kept the Lyr because I knew I was going to purchase other headphones in the future that required the extra juice just in case.

 

Yes I had the OP627 mod on the EF-5. It was quite a nice improvement to the EF-5. I HIGHLY recommend it if you're getting the EF-5 but installation can be quite tricky.

Is it the mono OP627 adapter height?  I understand you have to put spacers to reattach the acrylic plate?  Any other installation issues I should be aware of?  Im not a DIY type with tools and such!!

EF-5 smoothness with 500's doesn't mean tremble roll-off or lack of detail does it?  

 

I guess my question is this, if you were planning to stay with the 500's, which amp would you pair it with long-term?

 

I know I'm a pain but everyone else that has experience with both only talk about power and headroom, while others are moving onto Emotiva Mini-x from the Lyr for even more power for the 500's.

 

I don't understand, does the scaling of amp power make that kind of difference sound wise with the 1mw recommended  500's?  

 

Thanks, I have pending invoices for both units but can only afford one at a time and I'm itching to pull the trigger.

Answer to first question - the amp with adapter will be a little too high so it will stick out. What I did was a bit weird to make it work so that the internals would be covered. If you look at the guard rails for the tube, there are 2 acrylic pieces that have 2 beams supporting them. There are 2 beams that support it from each side with a total of 4 beams for 2 acrylic pieces.

 

I took the top 2 beams and screwed them in where the top cover screws go in. So it kind of looks like the cover piece is slanted. I then cut out some small styrofoam pieces to cover the openings to prevent dust from going in.

 

Below is a poorly drawn picture to try to illustrate what I did

 

 

 

Answer to your second question - initially the EF-5 with the original opamp and HE-500 sounded ok...detail was not as great as I thought it would be and it was a bit TOO warm. However with the modified opamp (http://tamaudio.com/store/index.php?route=product/product&product_id=91) everything changed afterwards. From what I can remember (and this was a while ago), detail was increased significantly and everything became more 'fun'

 

If I was ONLY using the HE-500 I would personally go with the EF-5. HOWEVER for the Lyr i've only had the stock tubes which I hear aren't as great as various other tubes. 

IF you aren't only using the HE-500 I would say the Lyr. Especially since Schiit continues to update their current products, you might get some upgrades to your amp/dac.
