Hi, I have problem with Hiface USB/SPDIF converter. I downloaded their driver and installed on my computer. It can make sound but with heavy continuous clippings. Do you have such an issue?

Is the internal headphone amp in DAC1 a match or good/okay for Sennheiser HD800?

Did Purity Audio K.I.C.A.S go out of business?

I am considering Teralink X2 with 6x AA batteries against unmodified Hiface one (not two).    http://www.ebay.com/itm/Teralink-X2-Native-24bit-96k-USB-to-SPDIF-I2S-Converter-/251394290149?pt=US_Home_Audio_Amplifiers_Preamps&hash=item3a884471e5  ...

I need a headphone for quiet office.   I am deciding between DT 770 (250 ohm) and DT 48 (200 ohm). I have amps.   I listen to classical music mainly.    

Though it has two pair of tubes, the sound signature let me believe it might be partially solid-state.   How do you think?

I am looking for a connector and soldering kits to shorten the cables of Denon D2000. I am going to cut from the plug end, shorten the cable and fix a new connector.   Some people on this forum has awesomely cut the cable of D2000 and D5000. See this following link...

I just got Denon D2000. I love it but the cable is too long and heavy.   What shall I do with it? What plug shall I buy and how shall I do with it?

What is the standard CD that you head-fi/hifi guys prefer to listen for testing a headphone/speaker system? What do you listen when you are writing a review or comparison?

Here is Beyerdynamic DT770 32ohm version. The plastic parts in the red oval circle are fixed by metal screws. It turned out that the plastic part ( inside which the screw should sit) is so loose that it cannot hold the screws firmly.   That results in dissembling of the plastic parts and...

Does 6N6P-i or 6N6P work on Little Dot MKIV regular version as power tubes? There are a lot of 6N6P tubes on ebay. sellers are usually in Russia or Ukraine. They are cheap, say, 8 tubes for $30. I wonder if they will work on MKIV. Which is better? 6N6P or 6N6Pi?

(This tread is dedicated to MKIV regular version. There are other threads dedicated to SE version.) I have listened to my Little Dot MKIV head/pre amp for a while now. I wonder if there are other people who are also thinking about tube rolling on this amp. Let me gather enough info here...

I just got my Little Dot Mk IV amp/preamp. I am using it as a preamp. There are some issues. I found out that the speaker ringing with the music, especially sensitive to mid and low frequency sound. When I silence the music from the source, the ringing will soon stop. I am sure it is...

I have a set of KEF speakers driven by Rotel power amp. I also have headphones sennheiser HD650 and akg K501. With speakers, I will listen to headphones much less often. But I cannot give up Senn or AKG completely. I need a preamp to connect to my power amp. Probably I prefer a tube preamp...

I got Teralink-x usb/spdif converter recently. It cannot work with win 7 and my DAC. I did not put any software into my win 7 yet. What shall I do?

repost here: I am currently traveling to China and in a big city. I want to bring back a USB -> SPDIF converter. Which shall I get in the market? My budget is around $60.

Can you help me compare Darkvoice 336 vs KICAS Caliente for sennheiser HD650? I failed to find threads comparing them at the same time.

Which is better with HD650: Head-direct EF1 or Darkvoice 336i/336se? I found threads claiming 336 is good with HD650. But I also found serious reviews claiming EF1 is better than 336i/336se. I have not yet found a lot about the combo of HD650 and EF1. I am confused.

I am looking for a DIY tube amp for HD650. Would you mind giving some recommendation?

Is there any AA/AAA-battery powered Flac player with a good sound?

is that possible? will it happen in the near future?

I think 50 dollars for Sansa Fuze 2Gb is a better deal than over 60 dollars for Fuze 4GB. IS there any difference between reading music from the original flash memory and from MicroSD card?

I am giving up the idea of buying Sansa Fuze

As iPod Nano is way more expensive than Sansa Fuze, i am inclined to Fuze, Any other suggestions for line-out DAP which can play APE and FLAC. it seems that fuze is money efficient at least. I just want to connect the DAP by KICAS to HD650.
