SuperMicro IV just arrived

The fedex man dropped a package in my lap about 5 minutes ago, and I just plugged into my new Xin SuperMicro IV. I don't have a digital camera with me, so sorry--no pics today. Construction/case is quite similar to SuperMicro III, although the case is now engraved w/ the name of the amp and the in and out jacks labelled. The volume wheel is more recessed than on the SuperMicro IV, eliminating any chance of accidental change in volume while the amp is in your pocket. The battery contacts are still the same (thin little pieces of copper flashing--be careful they break).

I'll be listening this afternoon and will post impressions. After 2 songs listening w/ Laptop>Transit>MicroDac>SuperMicro IV>GS-1000's, I can tell you that this is one kick-ass little amp!! (very clear; very crisp; very revealing). Xin is a magician!!

You guys are going to be happy. More to come.

Mine should be here early next week!

Comparisons to the Xin SuperMicro III?

I'm still furiously plugging, unplugging and comparing. So far, preliminary impressions with Laptop>MicroDac>amp, Iriver>MicroDac>amp, and Iriver straight to amp using analogue lineout are--well--inconclusive with the GS-1000's.

There does not seem to be an "order of magnitude" difference between the SuperMicro IV and the SuperMicro III with the GS-1000's. It's really too early to give definitive impressions, but on some tracks the III seems to sound better, and on others the IV seems to sound better. (Since I usually listen to the MicroAmp with the MicroDac, I had frankly forgotten just how good the SuperMicro III sounded with the MicroDac).

Thus, so far, I can't say that I see a world of difference between the amps; they both sound excellant.

My intended use for this amp is with the Nano or Iriver using IEM's, so that will be the next round of testing, and the one that is most important to me personally.

It's probably best if I just keep my trap shut until I've really had a good listen; snap judments with new toys are often misleading.

Edit, a few minutes later :
I couldn't resist one more premature observation before going home: quick testing with E4c's revealed a much more noticeable difference between the III and the IV: The IV offers more soundstage; a LOT more. I tried it with 2 sources: the Irviver>microdac>amp, and the Denon playing SACD downmixed to 2 channel>amp via analogue RCA/miniplug adapter. In both scenarios, soundstage with IEM's was pretty freaking amazing.

With the SuperMicro III, the sound with IEM's is sweet but kind of two dimensional. With the IV, it's 3D all the way. Preliminarily, I will even say the perception of soundstage with the SuperMicro IV and the E4C's is better than it is using the Headroom MicroAmp in the same configuration. Now that surprised me. The E4C's now sound more like full size cans than I would have thought possible.

All of this is subject to change of course, I'm very much in the "first kiss" stage of my relationship with this amp. That said, the difference in perception of soundstage with IEM's is not subtle, and I think it's real. And real good.

Now, back to trying to keep my trap shut until I've had more time to listen. (I'll probably fail miserably and wind up posting again tonight). God this is fun.

thanks for sharing some impressions, comfycan. so it looks like the micro can easily drive the GS-1000, that is simply amazing.

regarding the 3D soundstage that you're hearing, do you think it is due to the new 4 channel technology? you're in the perfect position to tell since you have the 3 channel micro.

Eager for some more Nano -> Line out -> amp -> e4c comparisons!

I hope so! I'd be very interested in how the K 701's sound with it.

It has arrived via Global Express mail, very quick delivery to Sydney!

Ordered on 17/6. Shipped on 24/7. Arrived on 28/7.

Ordered SuperMacro IV with default config; OPA134.

I can only compare it to the Corda HeadFive and Maxi Moy Signature with OPA637. After listening for only a couple hours with k701's, its in another league compared to the Maxi Moy - everything is much better. Compared to the HeadFive, it has slightly more detail and bass.

Amazing sound really from something so small.

This is great to hear, as I always felt that the SM3V6's biggest shortcoming was soundstage. I felt the Porta Corda III was better even in this regard. But the tonality of the SM3V6 was better than the PCIII.

ALSO: I got my shipping notice today! WOOHOO! Ordered 6/26, shipped 7/28.

Got my shipping notice today

I ordered a XIN SuperMacro IV 6/30 ,got my shipping notice today 7/28. Hey is XIN in Oregon? Shipping notice sez Priority US Mail,I'm in N.C. so I'm guessing 3-5 days to arrive.

Cheers,
Robert

Hi Comfycan,

thanks for the mini review. Would you rate the IV ahead of the headroom micro amp then?

Why did you get the micro instead of the mini?

I need something for my ER-4 and DT880's. Only using the line out on my AV710 at the moment

Thanks,

Steve.

Aluren,
I am not technical, and honestly don't have the foggiest clue how Xin's amps work.(Actually, I think perhaps he made a deal with the devil at the Crossroads; sold his soul 'cause he wasn't using it, in exchange for the ability to design magic amplifiers). (I hope you saw "O Brother: Where art Thou?; if not, you probably think I'm a nutter, but I digress).

I think the GS-1000's just plain sound great no matter what you plug them into. Soundstage/headstage is pretty much going to happen based on the design of the phones. That has been my experience with them thus far, and the fact that I noticed no immediate, significant difference between the SuperMicro III and the IV with the GS-1000's would seem to support that as well.

I've been doing A/B comparison of my I-Tunes collection on the Nano with the SuperMicro III and IV for the last hour or so with my E4C's, and so far the soundstage difference is holding true. I don't know if the term "soundstage" captures the difference completely; these are subjective terms and I'm not sure they mean the same thing to everybody. The difference I am hearing is best described as a more natural "3d" experience with better separation between vocals and instrumentals, and a more "open" sound. There is also more clarity--the III sounds kind of "flat" in comparison.

Most of the songs on my Nano are a hodge-podge of miscellaneous tracks leftover from my pre-headfi days; My primary music collection is in Flac on my laptop and Iriver H140. All files on the Nano have been either enconded or transcoded to ACC (some 128; some 192), and some rips were done better than others. I always felt the SuperMicro III was pretty "forgiving" of lower quality music files when used with just a lineout rather than a standalone DAC plus amp, and that seems to be holding true with the SuperMicro IV as well.

I'm loving it!

More to come, I'm sure.

It's on the list of things to do--probably tomorrow if I can sneak away from yard work and such.

Looks like i'll be looking forward to that! Exactly what I was looking for from this amp. Once again, I must thank you for the suggestion to purchase this from a couple of weeks ago!
