Maverick Audio DAC/Amp - Page 155

thanks, I'll just listen out to see if the D1 sounds different over time.

Alrighty then, is it a drastic difference?

I wouldn't think so. There's nothing to burn in except Caps so its less noticable compared to speaker diaphrahms

Just got my D1 today in the mail.

Worked fine for a wile, but then, weird.. At first my D1 just stopped working, as there was no audio from either tube or regular output. 

Then I decided to switch the opamps of the output with the headphone one, and it worked again.

Some how the non-headphone opamp just stopped working. If I max volume, I can hear a bit of static with music. It's very slight.

I didn't touch anything!!

What do you guys think about the Maverick D1 vs the Cambridge DACMagic?

I can't seem to find any opinion on it.

You can find a review/comparison here: http://www.digitalaudioreview.net.au/index.php/audio-reviews/digital-source-reviews/item/80-maverick-tubemagic-d1

Is your device working again?

I ordered the LT1364CN8#PBF and  LM4562NA/NOPB  opamps last night to try swapping them into the D1. Very excited to try them out as it'll be my first time doing opamp changes haha! Sooo now can somebody tell me where each of these opamps go?

Hey everyone,

Hopefully I'll get my D1 soon. That B-Dawk20 got his in only a week is comforting, if that holds true I'll get mine tomorrow.  But I haven't got the 'shipped' e-mail yet, so... 

I do have two questions. 

Question 1) 

Do I need to buy an adapter to use as riser in the DAC opamp socket to use the brown dogs I have? Doesn't seem to be much space there. 

Question 2)

Now I have to find that one spot in this little thread, here it is;

WE 396a, has better weight in all spectrum plus better headstage and separation. Only thing I am not happy is it doesn't sound as airy/high extension (may be this is what pp refer to has dark), but I still breaking in the WE. To me, the winner is sure WE.

My fully moded D1. Sound totally diff comp to stock. Achieving what I want: balance btw dynamic and smooth sounding, airy high, weighty mid,midbass and very reasonable bass extension, fantastic separation and sound stage.

Am thinking of an upgrade to WE396A but i don't really understand the 'darker background' description of the sound of WE396A. Is it also the similar laid-back sound?

This is another post where Mav explains how to do the tube out to hpa in (couldn't get the quote thingy to do multiple quotes, I haven't figured that out yet as I'm not a big poster, my sense of humor gets me in trouble!)  I'm bolding it to so you know where my ramblings leave off and the quote starts.

"my latest version is to solder connection from tube out socket to a female PC fan connector and plug to HP amp in. You can see it in my photo on top of page 94.

The easiest way of doing it without voiding your warranty will be solder a RCA connector to female pc fan connector wire to feed the tube out to internal HP amp. But this way you have to leave the case off. Last time when I did that the volume is too hot (first version high gain D1 I have).

Run a connection from tube out to line in won't do it cos we can't select coax/opt/usb input along with line in right? I you want to do it this way you will have to cut the internal line in wire and solder it to female pc connector and plug to hp amp in which is what I did initially. I eventually discard this routing cos the line in have coupling cap feed to HP amp input coupling cap again. Just too many coupling stage and it degrade the sound quality too much. Besides, the external connection pick up AC noise if too close to power cord.

The biga$$ed bold is mine in the first quote.  I realize that this mod you will lose the tube out RCA's, at least I think I realize that.  But this mod did not make it to the condensed thread and after this little discussion between Mavwong and uelover, I never heard this again.  Did it not pan out, hopefully one of the two will chip in, cause I may just want to do something similar.

Enough with the questions, hope someone can help.

Good Day.

Ooo. Thanks for the link.

I swapped the opamp from the headphone socket to the main output socket and it works.

So I have it in there at the moment, while the other opamp seems fried.

I messaged Ryan, and he's sending me another opamp for the fried one! :)

Oh, also, I can't seem to clarify the rate that the D1 accepts.

It seems that the USB only accepts 16bit/48khz.

However, a review on here at headfi says that over optical/coax spdif it accepts higher? Such as 24/96?

Yes? No? Maybe so?

That big modification never made it into the condensed FAQ because instructions and details were never provided. I was really hoping to see how that was done but I never heard back from that person.

I sent an email to Ryan asking for any information about the upgraded D2 version and this was his reply

"We don't have a confirmed release date. The original release date has been pushed back as we want to make more changes in the design. It might be ready within next 2-3 months, it might need more time. 

Please do let me know if you have any further question.

Cheers,

Ryan"

Too bad it's being delayed but it's very good that they're taking the time now to make changes and keep customers happy

Also, I have a Gamma Y1 lite usb DAC that I'm not using anymore since I got the D1.  After reading reviews that the USB dac of the Maverick isn't all that great, do you think I might be better off using the Gamma into the analog input of the Maverick and then using the Maverick as an amp/preamp?

I'm gonna give this a try in a few days once I finish exams and can just use the input switch of the D1 to toggle between the Gamma and Maverick's own USB input.

16/48 it is for the D1...

Thanks Spanky, I understand.

Now on to the other question, will a brown dog adapter fit in the DAC opamp socket or do I need to order one or more sockets/adapters to stack so as to raise the brown dog adapted opamps enough to use.  I'd like to go ahead and order them if I need them so I can go ahead and roll my opamps.
