50 comments and one person that might buy one haha :-p
Just found that humorous!
Listening to the HPA-01 through TH-900 and source A&K 240. Playing DSD albums right now it's JT beautiful vocals, bass and guitars playing against a black background makes me smile and tap my feet. Favorite track is Secret O' Life. On the best of Marvin Gaye What's Going On, the sax intro to Marvin's strong vocals. Brings me back to the good old days when life was simple. On the rock side, the Division Bell, Pink Floyd What Do You Want From Me, David's guitar work and vocals really shine. In my opinion the HPA-01 makes the vocals stand out. Used the TH-900 with the voltage output. Tried the current with my HiFiMan HE-500 it does make a difference in sound. Looks like the best of both worlds. I'm happy with this buy.

To my ears it just sounded way better with the voltage output vs. the current mode on the Fostex. I haven't tried the beyerdynamics or the Fostex TH-600 yet. Too many headphones so little time.

I see. Since I have TH900/T1 as well. I found this amp is super with current mode for T1. And I am using current mode for all phones... Your comments drive me to have a try with my TH900 on voltage output as well.
Hey everyone,
We’re happy to report that all of the orders have been shipped out! A few orders don't have tracking yet, but it will be uploaded shortly.
Thanks again for the support guys. Make sure to share your experience with the Bakoon HPA-01 Headphone Amplifier on Massdrop.
If there’s anything else we can do to make your Massdrop experience better, feel free to email us at support@massdrop.com.
Hey Guys,
These were shipped by the vendor and are currently undergoing clearance review. Due to this we do not currently have an estimated arrival date. As soon as they arrive at our warehouse and the bulk order is broken down we will let the group know.
Thanks for your patience and expect an update from us on 8/18 or sooner if something comes up.
Hey Guys,
The vendor is still preparing the groups order for shipment. We will stay in contact with them and update the group accordingly.
Expect an update from us on 8/13 or sooner if something comes up.
So excited for this :D
Hey everyone,
We’ve submitted our order for Bakoon HPA-01 Headphone Amplifier shortly after the drop ended.
Now that the order has been placed, Bakoon is preparing it for shipment. In the meantime, we will also be getting our warehouse ready to handle the reshipment of the product to everyone as soon as it arrives.
Expect an update on Thursday or sooner if something comes up.
Cheers!
One question about this that comes to mind is where would Massdrop customers be going for battery replacement if necessary?
Or will we be able to replace them ourselves? I understand the batteries are a common type, but they are glued down, right?
Sanlitun
Hey Sanlitun,
Bakoon just told us if the battery ever dies, they don't recommend to attempt to replace it yourself. They say just ship it to them and they'll be happy to replace it for you.
RyneWeiss
Ryne, you have done great job so far... So actively join in the discussion thread to answer all concerns and questions. That is helpful.
One reviewer that said the HPA-01 was "85% performance for 60% of the price" and another one said it was "90% of the sound of the HPA-21". So somewhere in the 10-15% lower SQ is where consensus appears to land, although this is all highly subjective of course and dependent on what is feeding the amp and what cans you are using, etc. Also the curve starts to really flatten out in this portion of the "cost/performance" curve, where each incremental X% of SQ costs more and more moolah, so a straight comparison is very hard to do. Very tempting though!
Uno mas!
Well I'm in. I don't know how well it will gel with my Editon12s but I need to get off the nasty power-line at my place(that has a habit of frying electronics. :/) If it's not a good match it'll be easy enough to sell it and only be out the cost of shipping.
We only need 3 more people!
KevinSommers
Make that 2 more as I'm in for the lowest price. Hopefully this will go as I can't wait to try this with the Fostex TH-900 and 600. This headphone stuff is driving me nuts and Massdrop isn't helping much by posting good deals. Aloha.

Icing on the cake: TH900 sublime pairing with another SATRI Bakoon amp http://www.headfonia.com/fostex-th900-and-th600/
We need to try harder to make lowest price available... :)

$2880 for 15%~20% more performance in terms of sound quality? I'd say no... :) No offend...
jonas
Is it even that much? I've read accounts on head-fi where those who heard them side by side were hard pressed to even find any differences. It seems the primary difference is more gain on the HPA-21 and the interconnectivity with the future Bakoon SATRI DAC.
The picture of the back of the unit says 110-240V and 50/60Hz, so guess it should be okay. Looks also to use a DC power source per the DC plug slot on the back.
mscott58
Thanks! I can't believe I missed that.
mscott58
The power source is a charger/transformer, so you just need a plug adapter.
Does anyone know if the amp can be plugged into a 220V socket? I do not live in the US and I can't seem to find any information on the manufacturers website or any other forums. Cheers!
Is this the most expensive thing that's been listed so far?
Dynamiklol
After asking the people around me, we discovered that the Stax drop was more expensive by $5 (first drop at $1599) but the $600 discount off of MSRP for the final drop price on this is the largest dollar discount we've ever offered.
I was thinking of buying this (first AMP) for my newly purchased Beyerdynamics T1. But reading last couple of posts... would it best for me to get a 'high impedance' amp, despite this being a very good price?
Fryzie
It has a voltage mode which will work on all headphones. As for using current mode with non linear impedance headphones (not high impedance, it's just that high impedance cans tend to not have flat impedances), your mileage may vary.
Is this better or the Woo Audio WA2?
mydonkeykong
It’s dependant on the headphone. The Bakoon current output is designed for low impedance headphones like Audeze or hifiman planners. It works best with those. (at lest according to reviews of the HPA-21). The voltage output can work with any headphone.
The WA2 is OTL amp designed to work best with high impedance headphones like the Beyerdynamics or Sennheisers.
Balthier
Hey Balthier,
While the Audeze and Hifiman planars are low-impedance, they are resistive so they don't react to changes in impedance, which is why they work very well with the current output of the Bakoon. Low-impedance non-resistive headphones will be massively underdamped by the current output, and so you'll want to use the voltage out for low-impedance non-planars.
Basically, current out is good for very high impedance headphones and planars.
Quite exciting amp....
As a dominantly IEM user who also owns the T5p and TH900 how well will this power my IEM? I am hoping to feed it via HUGO, thanks guys.
Found a review comparing this with the Questyle CMA800R: http://www.6moons.com/audioreviews2/bakoon/1.html

You can listen to it when it's plugged in. While it's plugged in, it still uses the batteries as a buffer to keep the power stable. In fact, I am fairly certain that the batteries aren't in it to be portable so much as they are to keep the power clean.
Sonido
I have found the review is rather hard to read .
I thought I saw some new gear in the photos of the MD table at the SF meet. Hey, CanMania and the DC meet will be happening tomorrow and this weekend. There's still time for you to hop on the redeye with this and the Questyle in your bags.
Wow, the HPA-01 was just released--and here it is with a $600 discount. The gain control along with the current +voltage outputs make this a very interesting amp drop. I'm looking for a new amp for my LCD-Xs and I've heard the HPA-21 is very nice with Audezes (and the HD800 and TH900). Seriously thinking about this.
I heard the current mode is more for planars? Something to do with the flat impedance curve in those I believe. Current mode messes up the frequency response with headphones that don't have a flat impedance curve, hence the changes in bass and treble.

I don't recall anyone trying the K812 with the current mode output at the meet, but I'm certain that it would pair very well with the voltage out.
RyneWeiss
Well recently I've been digging the Shure SRH1540 at work, and it looks to be in the same boat as the TH900 and K812, as far as being low, flat impedance and dynamic headphones. Currently, using Schiit Vali with my work setup so it's less than ideal. I was always interested in the HPA-21, so committed! :)
Will be interesting to compare Questyle and Bakoon side by side.
Now to find where I can sell my firstborn...
Surprised to see this here. Undoubtedly one of the best headphone amps available at any price. I'm in.
