Where did you get these?

Can you tell me what a major difference between 400 abd 400i? I owned 400 before but had to sell it cuz it was not as good as I expected. Thanks!

I used to own HD600 + Modi + NFb-12. I preferred NFB12 DAC. Just FYI :)

My condolences to you and your family. I'm so sorry to hear that.

Has anyone tried irDAC and Matrix mini-I pro?

I'm looking for the new DAC/AMP to drive my Lcd2. I'm using Modi/Vali now and I'm not so sure if it's worth upgrading to Matrix Mini pro. I love the small DAC/AMP because I travel a lot.   I like the Matrix because it comes with headphone amplifier, good DAC chip, and dedicated display. So...

This is an awesome review! I love the fact that your comparison was based on what did you REALLY hear from these two stacks regardless of their specs/prices. I'm using the Vali/Modi and I was wondering how better the sound quality would be if I upgraded them to Asgard2/Bifrost (or LYR2/Bifrost)...

I'm getting confused about this Schiit. I'm planning of upgrading to Bifrost and I think Wyrd probably helps improve the USB signal from my MacBook Air. It seems like I have two options now.   1. Getting a better USB cable. I heard from my friend that the good USB cable can decrease the error...

I think M50x is the best option under $200 price point. They have decent bass, and wide soundstage.   Have you ever tried Ultrasone? they are good choices too.

Can't wait!! I'm using Schiit stack and I really love it. I was thinking of upgrading to LYR2+Bifrost Uber before but since I have four headphones and will receive LCD2 soon, so I think I will go for the flagship amp and dac.

I'm using Vali+Modi with MS2is now. however, I will receive LCD2.2 soon. I like a tiny DAC/AMP as I always move from one place to another place. Is it worth upgrading to Pan am+Gateway? There is a discount on Alo website.    My original thought is that I would go for LYR2+Bifrost. But if...

Hi,   I had used the Ultrasone pro 750 with NFB12. I really like this combination, the NFB12 help to reduce the high treble sound from my Ultrasone headphone.   However, I had given NFB12 one to my best friend, and I got the Yulong D100 mk ii for the replacement of Audio-GD NFB12. The...

Thanks for the great recommendation :)   Actually, I am considering Yulong D100 MK ii as well, but I'm not so sure whether it's worth a try?. Are there big differences between HUD-mx2 and D100 MKii in terms of sound quality (I just need the good DAC/AMP to pair with my Ultrasone pro 750)  ...

I'm considering between Yulong U100 and Audinst HUD-MX2?  Which one is perfectly match with my Ultrasone pro 750? I had used the Audio-GD NFB12, but I just gave it to my brother.    Please help advise :)

I have a plan to upgrade both portable and desktop system. Here is the current and desired specs.   Desktop ======== From : Audio-GD NFB12 + Ultrasone pro 750 ...   ... To : ODAC + ALO m2m Silver + ALO the national + Ultrasone pro 750   I personally like the sound from ALO amp...
