PC is still somewhat trouble to me, but iPad can be a convenient device. Not all DACs support iPad w/ camera kit, any one tried it on Bifrost?

Though HD598 may be a much easier & more money-saving choice for me, I'm going to get a HD650, it worths trying   Therefore, I need an amplifier suitable for HD650 and THD (assuming it can output clean & uncolored sound). I used to listen pop in most times, classic sometimes. I don't use a...

I was going to buy an ASUS Essence STX for my desktop, however I found some USB DAC such like FIIO E17 (at the similar price range) is also attractive since I use laptop sometimes. Not sure whether they can compete with each other, for listening music purpose only.

I'm looking for a decent IEM for my iPhone 4 to replace current Apple IEM. I know iPhone is not a very good source, but it's the most convenient way to me.   I tried IE6 (& IE80) of my wife, they sound significantly better than Apple IEM. Sennheiser is the most famous brand in China, and...

I'm going to buy a Sennheiser CX400/CX550 for my girl friend's Ipod Nano 5th to listen Michael Jackson, but later I found IE6 looks much better as a Christmas gift. I heard that for some relatively high end earphones the sound can be poor without an amplifier. I don't have and not going to...

I got a LM4562 and a Blackgate 3300uF@16V, and ready for mod. I'm not going to implement the third mod (ESD paper) due to cooling consideration. The question is about the capacity of Blackgate is 50% larger than the recommendation (2200uF@16V), since I was not able to get the specified...

It seems like a good choice for beginners, since it integrates some ability of amplification, also easy to use :-) Can some guys provide comments on this product? I have searched the forum but found very few discussions on it. I'm wondering with the similar budget, should I choose a...

X-Fi Music <--???--> HD555 I prefer to listen music on PC, and bought this sound card due to its naming. Later I heard that it is criticized as "not suitable for music at all", due to its poor DAC and amplifier, i.e. the analog output quality. What's more, though HD555 (50ohm, 112dB) is a...
