I knew that question was comming

. My HD has a custom power supply, it is fairly similar to the one in the HD 250 prototype. I finished it a few weeks ago and to be honest I can't decide which one I like better. The B22 has a more neutral, precise and clean sound while the HD has a bit better dynamics, soundstage and bass. I compared my B22 to the Extreme before I sold it and the differences were similar but more pronounced. The Extreme was still more dynamic and bassier but it didn't have enough detail resolution. Obviously, sound quality is a very subjective matter so other people might find much bigger differences than I do.

I haven't sold the HD and I doubt I'll do it soon. In fact, I might sell the B22 before it to fund a new tube amp project. As much as I like it I can't keep building amps if I don't sell some of them

.

Well, as you can see from my sig, I'm the lucky owner of three SinglePower amps.

But I don't mind, as I'm going to have them 'fixed' within the next few months, and they do sound better than anything else I've heard so far. The only reason I'm getting the HD250 is because of the claim that since it doesn't have any electrolytic capacitors, it should last a lifetime. (And since my Concerto is out of commision for the moment - hopefully it can be fixed - and the Extreme is seriously lacking compared to the Concerto and MPX3, I wanted to try this limited addition amp.)

My Concerto has a tubed power supply, and I really like being able to tailor the sound by those tubes in addition to the input and output tubes.

If I don't like the HD250 and I can get my Concerto fixed, I guess I will be selling the HD250 fairly quickly. We'll see.

I'm very excited/nervous as well. I'm #1 in the HD250 queue. The pics on the site are of my amp and that makes the wait even more painful. Llyod is just making a few last tweeks so it shouldn't be long now.

Now I just have to convince someone with some K1000s to drop in once I have the HD250 so I can see how those bad boys sound. Afrikane seemed to think they worked well with the prototype.

I recently purchase the nos telefunken ecc83 and it is much better than the sovtek 5751. The electro harmonix that i have been using also sounds good in different way. I went to a local store to look for an nos tube and I told the owner that i would prefer an neutral tube. He recommended me the tekefunkens so I took his advice.

Eventually, I'll end up using other headphones with the Mad Ear+ HD using this tube.

No problem. I'm just glad that what I was hearing wasn't all in my head! I bought mine from Sweetwater last year...$20 shipped was a deal I couldn't pass up as this is pretty cheap by tube-rolling standards.

Also, I didn't mention this in my previous posts but all of my GT-5751M listening was with my Grado RS-1s (w/ bowls). A really nice synergy here!

Ear+HD owners: Does anyone mate their amp with any Beyerdynamics (especially the 600 ohm version)? We all know the great synergy this amp has with low impedance cans but I am intrigued by the new T1 and wondering if this amp will have enough oomph to drive them.

I can't comment on the Beyer's cans, but my 300ohm HD650s are really, really good with the MAD Ear+HD. They sound full bodied with more volume that I need at 11 o'clock on the volume dial.

^I'don't have any Senns in the quiver but from reading the Ear+HD was voiced with a Senn HD600. I would love to purchase an HD800 or even a PS1000 but I will have to try to find a meet that will have them on hand before I drop the $'s

My friend who listened to the RS1 and the AD2000 greatly preferred the AD2000, due to clarity issues. He said that the RS1 does not do well with very complicated music, or even slow music. He said it does best with very fast, basic music. Would you say the Mad Purist amp makes the RS1 sound clearer?

 

[Eric1110]

Hi Nuge,

Can you give us a little more info about your friend's current set up? What amp. was used to compare the two headphones?

 

[Nuge]

I'm pretty sure he was just using a portable microshar u107 amp with a pico dac? I think that's his rig. He said the AD2000 is more clear and impactful and less muddy than the RS-1 on that setup.

 

[uberburger101]

If it helps, I had an AD2000 on loan from a friend for a period of time and here are some of my thoughts.

 

[Nuge]

Is the RS1 + Madpurist amp good for all genres, including rock, acoustic, reggae(bob marley), dance, electronica, and soul?

I use my MAD HD Super for all those genres (well, maybe not reggae) and find it holds up very good with all of them.

One word YES!!!

There is nothing the MAD amp can't handle and perform extremely well!
