Maverick Audio DAC/Amp - Page 66

How about a power strip going to your speaker system? That's what I did when I had a really obnoxious setup where the switch was on the bottom and back of the subwoofer under my desk.

hmm i actually considered that, but could that possibly cause damage my audioengines or my sub? Plus these speaker have a helluva pop when i power them up/down...

My old sub gave out a nasty pop too. But it did that with the onboard power switch and the power strip so I didn't think twice about it. They worked fine then I sold them. You should probably ask someone more knowledgeable in the speakers forum, I wouldn't want to inadvertently break your equipment with any ill advice

i forgot to to give my phone number .....i hope mine gets shipped out on time.

edit: just got the good news

"Dear igotyofire,

Hi there,

Yes we've got your telephone number from ebay shipping page.
Your order will be shipped this weekend, I will let you know the tracking code once it is shipped.

Cheers,

Ryan

@_Spanky_: can you update the FAQ thread about opamp rolling with respect to the following:

1. Always 2 opamps are mentioned and here is what I find from what you posted:

"I've got the LT1364 in the DAC (socket closest to the tube) and the LM4562 in the headphone amp."

So we should always get both type of amp and swap accordingly ?

2. Where do we get these ? I found the following link:

Linear Technology - Purchase Linear Products

One question I have is if they ship to canada (or maybe there is vendor inside canada) ?

3. You also mentioned an allen wrench for changing op amps. wonder why ?

Thanks very much

sfrancis, I edited with the following info:

Gave the full model number of the opamps in the list.
Added info about opening the case (allen wrench).
Added more info about opamp swapping.

I didn't add anything for a opamp vendor since I am not going to go through the internet and find a vendor that ships to every country. You should be able to drop the full model numbers in google and find a couple places that would sell them. I think Digikey or Mouser might but I haven't looked. To be honest, I got mine by requesting a free sample which I know is a no-no.

Thanks for the hard work. It's quite clear now.

Don't worry about the vendors. I already bought both opamps on ebay this afternoon. It's an easy find.

One question I have: when you say check DC offset voltage after changing amp, do you mean measure output of opamp against ground with a multi meter ?

Thanks

Yea, I just measured with a spare headphone jack I had, worked ok with a couple minor issues.

Thanks, Spanky. It's clear.

I am about to roll opamps for the tube output on my mav. Do i need to check the dc offset on them even though its un-amped? If so what's an acceptable offset?

thanks

and btw spanky... great faq!!!

As far as I know you can only check the headphone opamp output and that's the only one that matters. I would think that DC Offset from the DAC opamp would get filtered out by whatever amp it's connected to but I could be wrong. Also, there's no opamp for the Tube output unless you're talking about the DAC in which case there's only 1 opamp

Thanks for the support

I was under the impression the tube out runs both the opamp and tube at the same time. Thats what I was told when I asked much earlier in this thread. While the non tube out only uses the opamp.

I guess that's possible. I don't see why it would add that extra step to possibly degrade the sound. I'm not an engineer nor do I know the schematic of the D1, I just try to give a somewhat educated guess with the knowledge I've learned.

well I think the tube out just uses the tube to "degrade the sound" and make the output sound tube like

Hey guys. Just got a D1 of my own

Just a couple questions:
1. Will there be any burn in? Already sounds fantastic so if there's more then awesome
2. Will opamps significantly improve the sound? I wouldn't mind buying some opamps if that was so. How would one go about "rolling opamps"?
3. Why is the gain so darn high? Through USB I've set the volume to 8.30 with the HD650s.
