Are most buying the Mav D1 directly from Maverick's site? Anyone using the D1 with Denon AH-D2000s? I was set to order a PS Audio GCHA but the D1 looks to be a great option at a much lower price.

Hi Bill, nice to see you here on Head-fi. Now I know where you are getting your idea's from.

Note to self, when changing opamps for the Headout. Leave the default opamp for the DAC section. I replaced my DAC with the LME9720HA and it seemed to affect the DC offset on the headphone out.

What is that affect in layman's terms?

 

[Riverback]

High DC offset can damage your phones in the long run

 

[B-Dawk20]

Oh wow...did the combo I chose have a low DC offset? I'm kinda worried now.

How so? What difference did you notice?
 
 

 

[Riverback]

I got around -160mV/channel with the LME9720HA.
 
50mV/channel is enough to destroy headphones

Only if your headphones are not capable of taking in a full 6w ;D.  Bragging aside,that could be one reason people detected a difference in sound when plugging an opamp into the dac.

I have an lme49720ha for both of the opamps. I assume they are the same as your lme9720has? Mine are the metal ones attached to dip8 connectors.

Anyways, if you replace just the headphone opamp with the 9720 what dc offset are you getting?

So do you recommend I just buy the LM4562 for the amp section and keep the DAC stock?

Hi ss,
 
Thanks

Ordered my opamps today

 

[sizzlincok]

Just got my D1~! I have a bunch of tubes to roll! 
 
I personally don't hear a difference between tubes on my AudioEngine A5's... 

 

[B-Dawk20]

op amps came in, gonna plop em in soon. Got the LT1364CN8#PBF and LM4562NA/NOPB combo for the DAC and Amp. Here's hoping the apparently low DC offset holds true....or the gods hate me and make me the only person with issues lol.

 

[B-Dawk20]

Got my portapros plugged in to see if there are any issues or rather, if it kills them lol
