Apparently, the GF model uses the LF353N and not the NE5532 like the Mav Audio version. The plot thickens

Ryan has told me that a new version is going to be ready in 10 days. I'll probably get it and compare to my Beresford.

The LF353N is also what I have. Well it figures. The grant fidelity version is the exact same as the xs version. They even say so on their forum. And the warranty is even througn xs as well. I've always been skeptical about the mav. There are a few differences which is why I went with the one directly from the oem. But still at that price you still can't go wrong. But I did get the xs cheaper than the mav which is even a better deal. And since it is the oem version, I don't have to worry about it not being legit(not saying the mav isn't, just don't have to worry about it).

Have you rolled tubes in yours at all? I have one on the way, along with some NOS Western Electric 396a's and Sylvania 5670's. I got a pretty good deal on the GF unit, and it will be used in conjunction with my Behringer SRC2496 for upsampling/reclocking purposes.

Yes I have. I posted earlier that I replaced the stock tube with a nos ge 5670. It was a nice improvement over the stock tube(which wasn't very good). The sylvania should be a bigger improvement over the GE 5670. I use the opamp out to feed my speakers and the tube out to feed my stax amp. My lambda sigs were a little bright using the dac in my receiver. Using the tube output definitely has smoothed things out a bit. I'll probably do a bit more tube rolling in the near future.

I just talked with Ryan and here are the new improvements :

- Direct button to disable vol control
- Line-in socket on front panel
- newly designed front panel
- OpAmp in the DAC is "socketed". Makes it easier for people to switch OpAmp.

And here are some pictures of the final design :

From the looks of it, the line in, is just the analog 2 routed to the front. Don't see any major changes, other than that.


I'm starting to really warm up to the mav. Got it running via SS out to my little dot mkiii, and it sounds fantastically detailed, and still very warm.


Anyone know of any guides to replacing this opamp on the GF, or opamps in general, I'm a little hesitant to change it. Do we know the NE5532 is in the maverick, or is it just speculation?

As far as I can tell from the pics on the GF site, it appears to me the opamps are socketed. The pic isnt very big, so somebody with good eyes may want to take a look and see.

Hi, yesterday arrived my Xiang Sheng 01 Dac

http://www.head-fi.org/forums/f7/inf...c-01-a-443930/

Hefei XiangSheng Electronic Co.,Ltd - Display - Products - DAC-01 Multifuctional Decoders/headphone/pre-amplifier

I Replace the Chinese 6N3 with an Ericsson 2C51 a noticeable change.
I use it only as Dac IMHO is better than Zhaolu 2.5c.
The seller sent me a GE 5670 but is higher the 2C51.

Well, I've had Maverick for two weeks and I have to say I love it. Use it primarily as a DAC, though it works well as a headphone amp as well. The sound is beautifully detailed and very pleasant to listen to even after long hours. I'm running it through the tube (6n3) that came with it, I have already purchased a couple of other tubes to play around and see what works best. Anyway, after a week of burning in Mav sounds great and it's an awesome buy, it looks pretty attractive too.
As for the opamp speculations, quite frankly I don't give a damn what they put in it, the fact is it sounds great and if it takes horseshi.. to make it sound good I'll take it . By the way, Benchmark dac1 uses NE5532 and costs $1000, read this post NE5532 Opamp - Benchmark so it shouldn't be that bad ... there soooo many variables to make a good DAC ... Having said that I have no clue what opamp is inside the Mav, but it's doing the job well. I think that all three versions are pretty much identical, you just have to make a choice you're most comfortable with, sound-wise /price-wise you can't go wrong.

So BOCtunes, what gear have you used before that you can compare it with? Since your first post is unexpectedly enthusiastic, it has to be asked if you have any association with the company, or were you asked to make your post by anyone?

The Benchmark has a reputation for having a poor headphone amp, something I can attest to from experience, and doesn't used the NE5532 any longer, by the way.

Currawong, Do you remember when you were a newbee? It's not unexpected to have a newbee post very exciting impressions. Many things can amaze when your new to audiophile. I highly doubt if he's in anyway connects to Ryan or Maverick.

I have owned and listened to a lot of dacs and amps, and I have to agree with his statments. Will it beat 1000 dacs, no. But it's not far behind, and for the price it is an amazing value. It's definitely more than I was expecting. I primarily bought it to take with me on trips/vacations because of it's modest size. But this thing has been good enough to use daily with some of my other equipment. Right now I'm using the tube out for my staxs.
post #134 of 2567
Currawong: , I guess if my first post was negative it would make me more believable. There's tones of people out there who happen to be reading posts by you guys without ever contributing, after all, who wants to spend time answering association speculations after their first post. I merely expressed my experience with the MAV DAC and think that any of the three would be equal for the task. The Mav improved my X-fi output tremendously (expected) and is equal to my Marantz cd player (hence my unexpected enthusiasm ), that is all that matters to me. Hey Ryan, if you happen to read this, feel free to send me another unit since I'm so unexpectedly enthusiastic ... I will not answer any other speculations, have no time for it ...

Well if anyone cares/ is paying attention $210 for the new design shipping end of the month. They're up on ebay.

Ran into a problem with mine. The line out using the tube has gone out. Completely out, no sound or anything. unfortunately, I'm at school and I can't get the casing off with what I've got here. Maybe it's just the tube that went out, or maybe something more? I'm afraid to try and do a warranty repair, because of shipping cost, and uncertainty if I'd get it back. Any advice?
