Fostex HP-A4BL (the A4 with balanced output)
Nov 3, 2017 at 12:06 AM Post #166 of 401
This dac/amp really Drives my Sony's MDR-Z1R like a champ via the SE Cable, in the process of ordering a good custom made Balanced Cable, 4 Pin XLR. Plenty of Juice for the Z1R at 12 O' Clock, no need for High gain, will update once the XLR cable arrives.

This is my main amp/dac combo. I started with an o2/odac --> Yulong canary daart ---> these. I use em to power my Hd 800s in balanced, fostex th-900s and LCD-3Fs. Is there anything really better.

I agree, I really feel like this amp is seriously put to use on Balanced, it doubles the power output, it powered the LCD-2's with no issue, plenty loud at 12' O clock. Just ordered a Moon Audio Silver Dragon Balanced Cable for my MDR-Z1R, cant wait to get them.

Did Fostex forget to advertise this?
Was looking for balanced amp/dac combo and found A4BL, made In Japan, looks great, pretty fine specs for TH900 and X00.
Got last one from Rakuten for 399.
I see reports that its not fully balanced dac/amp, while others reported as fully balanced circuitry.
Will test it against Burson 9018 Conductor and Chord Hugo.

Hi, I'm kinda interested with this Fostex amp and was wondering if someone can help answer a couple of questions.

To my understanding, this can be solely usb powered and is good enough for single-ended connections. However if I would like to use the balanced connections, I'd have to get a seperate DC12V adapter to power the amp? Is there a dedicated switch for this or would connecting the DC12V adapter automatically switches the power away from the usb?

Also, does anyone know how does this dac/amp compare to a DAP such as the Onkyo DP-X1A in terms of sound quality?

Thanks in advance.

Uhhh, I'm pretty sure this needs a power source for all use. It comes with it's own power supply. This is my first desktop dac amp. I have used a modified Auzentech X-Meridian sound card, with swappable opamps,before this. I choose this amp for it's balanced out put and it's ability to play up to 11.6 DSD. I use it with the my HD 650 and it's on par with the best peruvian product that I can remember from 30 years ago. My modified Fostex 50rp's sound pretty darn good, with the unbalanced output put, as well.

This dac/amp is meant to be powered by the 12v power supply, if you want USB go with the older HP-A4, that's only USB powered.

I am doing research on DAC balanced headphone amps---I am looking at the Fostex Hp-a4 bl and Schiit Jotunheim.
Both are around $ 500 new. If anybody can give me some advice I would be grateful. My headphones are Focal Utopia and Fostex TH 900 with silver dragon cable upgrade.
I am treble sensitive if that makes any difference in these amps.
If there are other any other balanced/dac amps that are also high quality, please advise.
I would like to spend around $ 500----not quite ready to go crazy with all the recent purchases.
Thank You===

Quick question. Since this is a Made in Japan dac/amp, does the AC adapter that comes with it supports 100V to 240V?
