I currently use M-audio transit as digital source to moded Zhaolu DAC and wonder if anyone here can recommend a digital interface with USB->Coax digital out for laptop? Thanks!

Looking for a meet opportunity in Boston area, any information?

Hi, Just got a 9 feet Cardas upgrade cable for HD600. However, it's too long for my daily usage. Just wonder if there's any negative impact on sound if I DIY it and make it shorter, say 4.5-5 feet? Any opinion would be highly appreciated.

I found a pair of Griffin Earjams at RS this afternoon and found these things are amazing. I couple them with my MX500, which to me is bass shy. Immediately, I pick up a lot of big sound out of the couple Earjams with MX500. The bass is significantly enhanced and the overall impact is something...

Hi, I am looking for some NE5534's (made in 1979 to 1988) from Signetics. But I have no idea where to start with. If there's someone here happens to have some and is willing to let them go, please shot me a PM. Thank you very much.

I had a pair of ER4 but found it's a pain to use it for more than a few minutes. Just wonder what are the most comfortable canal earbugs?

Hi, I need a new stock cable for my HD600, but just wonder if the 650 stock cable could be used for HD600? Thanks

Hi, It seems that AD8397's a very cool dual chip with very low output impedance, high output current capacity (300MA) and more importantly, rail-to-rail voltage swing. Wonder if anyone here tried it before and how does it sound compared to other chips or even OP+BUF structured amps? Thanks.

I am planning a DIY calbe for my HD600. I wonder where I can buy the plugs and cable? Thanks.

Anyone has any idea aobut this baby? Looks so close to SM3. http://www.fixup.net/products/macro/IMGP0945s.JPG

Just checked Xin's website and found he has updated the website for SM3. There's even a promotion for the first month - get 2XBUF634 soldered on board for free http://www.fixup.net/products/macro/index.htm

This morning, I just happened to find the following post in Xin's Cool talk. There's no reason why I don't put it in here Quote from Xin's: "No kidding. After another sleepless night, I just finished the design of V3.0 of SuperMacro. As much as you do, I too hate endless upgrading. So, I...

This afternoon after the class when I checked my mailbox, I found a small box lying quietly in it. It's a SM V2.0! What a surprise to me. I couldn't wait to give it a trial. All the following impression is based on 30 minutes' listening. Equiptment: Indigo DJ+SM V2.0 with AD8610 (vs. V1.0...

In the past week, I did a lot of comparison among NE5534 and 227/627/637 in SuperMacro. Now I have to admit that NE5534's sound the best! NE5534's in SM sound warm but very transparent with a super super sweet and relaxing mid. No matter playing pop, jazz, rock or classical, NE5534's deliver...

It's mentioned in Xin's website that he has put off the Supermini project temporarily and started working on a DAC project. He will put a really high-quality DAC in the current SuperMacro and then add a SD/CF slot in it - the first high-end portable player in the world. It's possible that he...

My SuperMacro's back this afternoon with a new configuration from standard issue with AD8610 to the socket version plus some improvements recently developed by XIN. I have several OPAMPs (227, 627/637 and AD8610) in hand for head-to-head comparison. Under my first impression, Man, I'd say the...

Xin seems to be working on another ground-breaking project, the new Supermini. As he put it in fixup.net: "For the amp, the new SuperMini is coming soon, for $99. I cannot post the details now, but it is another ground break. Very slim aluminum cases with lots of colors and finishings to...

From XIN's website: "When the power switch is turned from "on" to "auto" position, the amp will sound like the battery is running out near the end of the timer and it'll shut off entirely after couple minutes." Also, someone mentioned that the timer will degrade the sound quality. I wonder...

I have been using my SM for more than 200 hours and it's fully burned in. Though it sounds fantastic with batteries alone, I would say it performs better with AC power than with batteries. With the AC adaptor plugged in, the SM deliver more consistent and better separated sound image while...

From Xin's website, I found that Xin's fixed the last thing - the back panel nicely and started to ship out the orders. Here's the quote: "Hi all, I held the shipping for the SuperMacro because I had been perfecting one last thing - the back plane. The battery contacts on the back plane...

He added 5000uf caps totally in the standard version (even more than what I have got in my SuperMacro Standard version two days before ). Two buffers per channel are still there. Moreover, it can add all four features! http://www.fixup.net/products/macro/ I hope I had hold my hand for two...

Never have I written a review for amplifiers as I am a non-English speaker and a newbie here in the head-fi world. I would ask for your understanding of my limitation in coming up with quality review as what Zanth and several other SuperMacro owners have done. I am just lucky enough to be the...

Hi, Is there anyone here can tell me if the modification of the Superdual done by Xin makes it sound different? As I have a SD that can benefit from the modification. If there's no audible difference after the modification, I won't bother sending it in. Thanks

Hi, I have been with my Creative Zen NX 20G MP3 player for months. it has 30mw+30mw headphone output. But what a pity, it has no line-out. From the test published by other guys, I noticed that it has a roll-off from 40hz. I want to do some mods. to improve its headphone output capacity and...

Hi there, I have a Creative Zen NX 20G MP3 players. I wonder if you guys could shed me some lights on how to improve its headphone output performance, coz it has no line-out. It has a 30MW+30MW maximum output. I wonder if replacing some capacitors will work. Thanks, Simon
