I wouldn't hesitate buying from that eBay seller. I personally got great service and quick shipping from them on the Windmill getters.

My unit does not wobble at all as well. No hum as well. Just a little hiss for my sensitive AD2000.

In addition , i stick four 3m rubber feets on top of that to make sure my set is "bolted" to my table. It does not move around easily now.

I'm using LT1364 for the DAC and LM 4562 for the headphone amp. So far so gd I would say.

Anyone using different opamp for DAC , care to share their results ?

I looked more carefully at the Mav box tonight. I have concluded that the wobble is not caused by the stamping of the metal. It's caused by the rubber feet themselves. I can see, based on the molding marks on the feet, one foot is about 1 mm shorter than the others. This causes the wobble. So, it's a double non-issue now.

DC offset is critical though, at least in my unit. - LME49720: 120/180mV DC offset (yeah, exact same as with AD823). Very neutral and natural but less kickbass than the AD823, I think. - LM4562NA: 0/0mV DC offset (!). It's now my opamp of choice although I thought that LME49720NA = LM4562NA... I guess not. - OPA2132: 0/0mV DC Offset... didn't listen very closely to this one. best regards. bearmann

What DMM do you have? Didn't you say couple of pages back that you got that 120/180mV also with LM4562? So, unless your DMM is not of high quality and very accurate, that variance between measures and different op-amps could resemble your DMM's inadequacy to measure such low voltages?

I'm using a normal Fluke DMM , the LM4562 is within the so called "safety" range , DC offset measured very low iirc less than 10mv.

The auction ended and they stopped relisting it.

get from mavaudio website direct ?

imo , it is worthwhile.

Mine wobbled when I got it, but I flipped it over and saw a little round ridge from the molding process was visable on three of the feet. I used a little piece of 220 grit sand paper and knocked the ridges off and it is stable as can be.

OK, I have stated publicly that I would never sit and listen to music on a pair of headphones.....this after spending 4 years in the Navy listening to headphone for 8 hours a day

. I do have a pair of Grado SR60s that I pack when I travel so I can have SOME music in the hotel rooms at night....but was never taken buy the sound.

Yesterday, I bought my D1 into my office from my family room and hooked it up to my computer along with my music external harddrive. WOW,

I never thought headphones could sound so good. I ment to do it just so I would not wake my wife with my music but I gotta say, I was impressed. Now, I am thinking about ordering another D1 just for my office. Damn, I knew I should have never started hanging out here.

 

[djnagle]

OK, I have a question and a comment.

Does the headphone side of the D1 "burn in" or is it burned in as I have been using it as a preamp in my main system?

I can hear "air" when there is no music playing and it get, not exactly loud, but very noticable when I crank up the volume. and, the first two clicks on the volume knob don't do anything then the third click is at a perfect listening level. Beyond that, it is too loud.

I was talking about the Raytheon Windmill Getter replacement tubes, not the mav itself, I already have one.

Hey Thearrow, what do you thing about the windmill? I will have that and the WE this weekend to roll.

@first post, I told you so

@second post,
Happens with sensitive low impedence headphones on the D1. The new production batch of the D1 might of been better for you since the gain was lowered, only way to fix it now would be a relatively simple mod. I don't get it on my headphones and the volume knob has a little more range between low volume, listening normal, and high. They make my headphones shine on new levels

so much so I integrated them with my entire system. I also am not completely sold on burn-in so can't comment on that.

I think I read somewhere that the Mav uses a Cirrus 24-bit/96 kHz DAC. If this is true will the DAC handle hires downloads?

Has anyone tried anything higher than 16-bit/44 kHz?
