I always think it would be nice to ditch the spacer and make wooden sleeves to slip into the outer cup. Some folks have advised using oven-cleaner to ditch the red as well...but that's a lot of effort just to get a pair of aluminum outer cups..

Hey guys, received the Ear+HD today. To my surprise when I turned it on (without a source at the input) I have a terrible popping/interference noise at 0 volume. Then I realized with the RS's plugged in either high/low-Z I had to turn the volume to the max to hear at a relatively mid level volume. Then I noticed the 1x12AX7 tube was not glowing at all.

Aout an hour later I returned home and turned the amp back on (12AX7 still not glowing), but through either the high/low-Z the volume was correct this time, but still have terrible noise at 0 volume, and no glowing from the 12AX7.

Has anyone experienced these problems before with this amp?

Can the 12AX7 be causing all of these problems? I also don't have another to swap out.

Any help/thoughts on this would be greatly appreciated being this is a brand new amp and I couldn't wait to receive it, its pretty upsetting, as of now. Thanks.

Great that you got your MAD Ear, but sorry about your problems.

 

Sure sounds like that tube is not working .

 

e-mail the good Dr. right away and explain your situation.

Sounds like the tube might be toast. Do you have any other 5751 or 12AX7 tubes to pop in?

Thank you, I e-mailed Lloyd and he also said it sounds like the tube, so he is sending me a new one. Do you have this constant popping/interference/distortion noise with no input at 0 volume?

BTW, with the volume turned up I can't hear the noises, and the amp sound very sweet after listening to it for only an hour. I can't wait for it to burn-in, I can just imagine how much more sweeter it will sound. Thanks.

I hop that is the problem, so I don't need to go through the shipping back and forth.

Unfortunately I don't have another tube to replace it with.

Its a constant crackling noise, popping/interference/distortion.

Is this what happens with a bad tube? Thanks.

no noise or interference here, what so ever. The amp is dead silent

Yeah, like I said this is even happening without an input source, so I hope its just the tube.

Blue or Purple xD label it with "PS1000 by Justin Bieber LE" sure you will get a lot of love as well as hate xD

yeah  it looks like pretty pink...

has anyone owned both the LD1+ and the ear+HD? Can you do some comparisons? it seems that these are the two most favorited and decisively decided "best" headphones amps for grados/magnums. I would like to hear from someone who can directly compare/contrast them....

Why not try sending an email to Grado and see what they suggest you to do as they know the best and it's not at all a pain! I tried sending an email to them once on my issue and they replied within 24hours which is good! And they don't torture you at all... They try their best to help! [no, I am not paid to write this xD it is really my own opinion just in case you are worried about anything ]

This i'll definitely do. Grado made them, so surely they'll know what to do.

Failing that, Mr. Chang is right, Grado's Customer Service is miles ahead of anyone else's. They have put up with my crap on a regular basis biggrin.gif

They stay fit, thanks to their wiring, Joseph69 mentioned using hot glue, and i might do that.

I would love to do this, if they weren't one of the early models, it feels wrong to change them that much :X (but oh man, it's tempting)

I use a hot glue gun to secure my drivers in their cups, it works excellent.

Regarding the polishing: i'm going to contact Grado first, see what they think. I really want the lettering to stay.
Regarding the hot glue: i think that's a good idea.

Don't know about survival of the lettering however.

Thanks for the suggestion, i'll contact Grado first, see how the lettering was done...

WJE came up with the best solution, which would be to anodize them.

I think they were originally clear coated, so i will clear coat them again.
As i stated above, i donmt want to ruin the lettering, on such an early model i want to keep it in it's most original condition as possible...

I am copying my response that I wrote just recently from the MAD Ear thread from the headphone amps forum.

 

I would say yes, there is a significant difference. I was not blown away , when I first heard it, but I did think it was better than the LD1+.  Now that I have heard it more,  I think it is safe to say that I am blown away.....I love it!

 

For me, I seem to need awhile with my cans and amps to really let it sink in and to adjust to the difference ....it takes me awhile to really soak it all in.

 

I feel pretty much the way that most people explained the RS1i & MAD EAR combo to me.....it just sounds magical....great synergy, indeed. Guitars have never, ever, ever sounded better :-)

 

I have not listened to my LD1+ since I have received this amp.

 

I will say that I did plug my AKG  Q701 into the MAD EAR today, and they sounded nice, but the same magic does not exist as with the RS1i. It does not even compare, IMHO.

 

I can't say whether the MAD EAR +HD is worth the six or seven times the cost of the LD1+.....but it is significantly better.

 

I really can not imagine anybody owning and RS1 not really enjoying what they would hear from this amp

 

I think I can honestly say, that if I had to live with this combo from now until doomsday....that I would be very happy.

 

I may add the PS500 at some point to my RS1i and Q701.....but I don't see this amp going anywhere!

 

The biggest difference that I notice are the highs are just completely silky, silky smooth, with all of the detail intact.

 

The instrument separation & detail are both also better.

 

That being said....the LD1+ is one heck of an amp for the price, and I still have mine.

 

Also, I have only listened thru the MAD Ear with my RS1i, I have not tried any other Grado headphones.

 

There are so many amps out there today and new ones popping up every couple months, so I am sure that there are many that work great with the low impedence of Grado cans.

 

I guess the MAD Ear is considered old school by todays standards....but the synergy with the RS1i is real.

My in-laws are nuts for antiques, and I learned the golden rule from them: never, ever restore something if it's still original, no matter how banged up it is...and if you must, keep all work to an absolute minimum.

That said, Frank Lloyd Wright isn't around to repair and refinish like Joe and Joseph Grado are smily_headphones1.gif
