Many of us Xin junkies feel the Supermicro IV is the best amp Dr. Xin has ever made and the best protable amp out there. But even the Supermicro IV has some limitations due to its diminutive size. Some are:

- Case for some is not strong enough
- Not a true 4 channel more like a 3.5 channel (for detail contact Dr. Xin)
- Even after the 4/11 mod the play time of 34 hours out of a AAA was not enough for some. Now is over 200 hours.
- Simplicity has been taken to the next level for a better sound.
- The volume knob in the Supermicro/Supermini was not liked by some.

Anyways, hope this helps.

For the record and FWIW try to control your tone. Your above request is not shall we say very polite. Honestly I do not have to answer anything.

However I will assume it was not meant to be agressive/offensive and will suggest you visit Dr. Xin's website for a full description of his 4 channel. His website is at: http://www.fixup.net/talk/topic.asp?TOPIC_ID=1759

I do not know, maybe Vorlon1 is interested or perhaps not. I have not seen him post so far.

Just kidding, I already PM'd him to meet and review this amp. Although with such a big cap I should let it burn in for 400 hours to be fair.

Yes. I would phrase it:

What the hell is 4 channel, answer me. . . Please. :6)

I agree. There isn't really going to be a true understanding what what this thing will sound like until after 400 hours and possibly 800. Hey! do I see room for a BlackGate bypass?

I ask because I'm not sure how one could objectively compare the Supermicro to the other amps without eliminating this variable from the comparison. I've asked some people about this and haven't yet found someone who has done such a comparison, so I thought I'd ask you.
Hi Filburt, you asked a similar question in post 34. I answered it in post 79. But to repeat yes I have tried well over 15 op-amps on the LE and in different locations. The Supermicro always sounded better to me.

So are you saying you really like the Micro better or really, really like it better? :^)

Xin lives 40 minutes from me now. I think I will have to go pay him a visit.

I saw your change in location, man would I love to meet and chat with him! For the record I do like the Supermicro IV, hope that is clear.

Is this an assumption? Because I thought you only got pre 4/11 version of supermicro and supermacro LE. Unless you heard the newer version from a recent meet.

Anyways, I'll be interested to hear your feedback on the new big supermicro pre and post burn in.

What is interesting is where I was working in China is the same Province Xin came from so I know what he saw and lived with there. I will most likely go up and visit in the next couple of days. I just got my car fixed, new engine. Eugene is fantastic. It is green green green and I ride my bike along the river on the way back from working as the hospital. What a change from China and Tucson, AZ.

So you like the Micro, that is clear, but I never assumed otherwise from your past comments. You know, I have never heard one. Maybe soon or maybe the Reference.

-_-

Sorry about that. I am so busy nowadays I can't remember where my posts are @_@

Did you use the AD8616 or the AD8615 when you did the comparison?
post #102 of 559
mrarroyo, can you give us your initial expressions when you get it? Then of course, non-stop burning in for over 17 days to get those 400 hours in I have asked Dr. Xin to hold off on my order of the SuperMicro IV until I make up my mind between that and the Reference amp. I'm hoping Vorlon will get to demo this soon =)

8616 was among the ones used, not the 8615.

That is what I got from Dr. Xin. As far as me listening to a post 4/11...very soon grasshopper. Vorlon1's is on its way from Dr. Xin.

Dr. Xin was great to communicate with by email today. First time I've tried to contact him and we went back and forth several times in a short time (me on my Blackberry, he I suspect at his computer). He said that information on the Reference Amp such as pricing will be made public next week.

I have a feeling that this name "Reference" is no accident. This is going to be his new premier amp. The SuperMacro will likely still cost more with charging circuit, switches and rolling options, but this will be the... reference Xin amp. I'm very interested. mrarroyo I do hope that you will test it with your 250 ohm DT990s. Depending on the performance and volume setting, perhaps we can do some useful extrapolation to 600 ohms from there.
