Fostex HP-A8 DAC/Amp and other Fostex gear
Nice review. Can you also help make some comparison for V200 and A8's internal AMP for HD800? Is there a significant improvement after adding V200 (I guess some details will not be as good as using internal AMP)? I'm interested in V200 which may add some warmth to HD800, but also...- netmask254

Fostex HP-A8 DAC/Amp and other Fostex gear
For my HP-A8, I use its remote controller frequently, however after several months usage, it becomes very unresponsitve and need to press hardly on the button (I'm sure it's not the battery issue), does any other guy encounter similar problem? Another question is that, have some body tried...- netmask254

Wanting To Import A Fostex HP-A8C From Japan; Voltage Concerns
Duncan1, thanks a lot for your advice! A8 is using a two-pin power plug, actually I tried swap the two-pin connection but no help. I think using a 3-pin power cord shall be helpful to this case but didn't try it yet since the user manual warned that not to change power cord :-) I will...- netmask254

Wanting To Import A Fostex HP-A8C From Japan; Voltage Concerns
Did you notice any sound difference between directly connected (after modifying voltage) and using a transformer? I notice that after modifying voltage, sometimes there is a few static electricity on the chassis even without powered on. I don't remember it exists when I'm using the...- netmask254

Crack;Bottlehead OTL
Does crack consume much power and generate lot of heat? I sold my Valhalla not because of its sound, but because it's too hot to get a good user experience in summer. Valhalla has a rated power consumption of 35W, however I can't get any spec on Crack :-) I'm also interested its size.- netmask254

Crack;Bottlehead OTL
My location China has a voltage as 220V. I heard Crack has a 240v version, is it also usable in my area without any sound quality loss? Besides, can someone give a rough ship weight of Crack since I need to calculate the oversea ship cost. Thanks a lot!- netmask254

Fostex HP-A8 DAC/Amp and other Fostex gear
Well, I also have many Chinese and Japanese songs :-) I usually tranform a whole album (rather than individual song) into one wav, and then category them into different directories. I heard there is a restriction about the total directory number and file number per directory (may be 32 or...- netmask254

Fostex HP-A8 DAC/Amp and other Fostex gear
I think many guys (including myself) have upgraded to latest firmware and play WAV via SD card. It's not quite user friendly (support only English & digital as sound track name), but after get familiar with it, I spent more time on SD play for its convenience (I use XLD to transform tracks to...- netmask254

Fostex HP-A8 DAC/Amp and other Fostex gear
A few more questions to A8 owners: 1 The default power cord is two pins without ground line. I notice my A8 has some static electrity after hours' usage. Did you have similar issue? I'm thinking to upgrade to an 3-pin power cord (a lot of good choices), but the user manual says not doing this...- netmask254

Quote: How about HP-A8's internal amp paring with HD800? I'm currently pairing it with HD650 but thinking to get a HD800. According to Headfonia's review, some DAC's details will be lost after connecting with an external Amp. I'm considering to build a Bottlehead Crack.- netmask254
