New Fostex HP-V1 Portable Amp
Dec 19, 2014 at 12:50 AM Post #121 of 220
Just picked up a brand new Foster HP V1 today and it works flawlessly. Only thing I've noticed is that there seems to be a loose part within the unit because I can hear something moving inside when I move the unit around? Do fellow owners experience the same thing? Is this normal?

The HP-P1 had the battery mounted on a plate that sat in grooves on the side of the housing wall. This would rattle a little given particular movement. Perhaps the HP-V1 is similar? 
 
Anyways, enjoy your new amp, I want one.

I think you hit the nail on the head AJHeadfi. On closer inspection of my unit, I found that I can move some of the components inside the chassis by forcefully pushing on the DC outlet on the outside of the chassis. I hope this is just a normal thing with the Fostex amps.  
 
Btw AJ, are you in Australia? If so, now is a good time to buy the HP V1. Noisy Motel are doing it for $599 on sale at the moment. Luckily my dealer was able to price match this for me. My dealer got in touch with the Fostex supplier today who mentioned that there will be a price increase soon (~$799), which is understandable, given the falling Aussie dollar.

Yes, normal and I believe unique to Fostex portables. Shake, rattle and roll.

Man, I'm relieved to hear it because I really don't want to be without this amp for any length of time! 
 
Because I'm paranoid, however, I would appreciate it if anybody else who has had experience with the HP V1 could confirm that it is normal for the battery to rattle abit.

you need to desolder the two caps and placing them horizontal:

drill the hole in the front, grind down the jack a bit in the height (marked), shorten the connections.you also need to grind
down the nut on one side ca 0.8 mm (had to be orientated upside at end):

you can use tp7- tp9 for the wires to solder, i use 2 x solide silber wires and 1 ooc copper wire:

you have enought place for the cables under the tube (you see here the nut side which need to be grinded down a bit):

if you want use wider 3.5 jacks you need to grind down here a bit:

I've just received the Fostex HP-V1 today on a Sunday!  I picked this up on Amazon Japan and with the strong dollar it cost me $382 including shipping via Prime.  I live in Okinawa, Japan so ordering from the Japan site is no problem and with free shipping as a Prime it's pretty cheap.  For example the Fostex HP-A8 would run me $731 with free shipping.  Another example is the TH-500RP for $664 with free shipping.
 
Now listening after a quick charge using the A&K 240 with the Fostex TH-900, nice bass on Japanese DSD recordings.  Can't wait till this breaks in as I'm already loving it.  There seems to me that the Fostex TH-900 loves to play through the Fostex gear as I've also got the HPA4 and it's a good match.  But I love the sound that tubes gives me.  Just thought I would share.

thats a great combination ak240/hp-v1/th-900, the last weeks i often used this combo with great joy instead of my desktop amps. the hp-v1 is my first portable amp that can compete with his bigger desktop brothers, reminds my a lot of the yamamoto ha-03, very smooth and natural sounding without loosing contour, you are very quick into the music instead of technique. you may notice that he needs 10-15 minutes to warm up. another great match is the ath-3000w, a little bit more mellow, less neutral but lovely. you will have fun with it :)

Just added a HP-V1 to my office rig too, stacking nicely with the HP-P1 and playing Jazz/Instruments/Vocals from IPC or streaming Pop from IPT on the AKG 271MkII. The AKG mids come through like maple syrup, very enjoyable Andrea Bocelli. Will be having lots of fun doing A/B on the other office cans later on (L1/AKG 545), might even bring the AKG 712 pro to work later on.
