Yea the Bottlehead Crack would be an expensive project. I really want a tube amp though, so I will hopefully end up making one eventually but I'm gonna work my way up. Have you heard one of the "Starving Student" amps? I'm curious how that would compare, or if it would be a good project while I...

Its that good, huh? Yea I won't be buying any $1000 hardware any time soon, so I'm sure its better than anything I could afford to buy off the shelf. I've never soldered or done any kind of electronics DIY stuff, so I think I'm gonna start with a CMoy or something, but the WHAMMY and Bottlehead...

Thanks, I've ordered the wingoneer kit you linked to and some supplies, and I am checking out info on the second link you posted, very helpful!

I'm thinking about building a WHAMMY. I see there is a lot of info on how to build it, but not much on how it sounds. Can anyone give me an idea of what commercially available HP amps this might be comparable to, and maybe some subjective impressions about the sound? For reference, right now the...

I'm thinking about trying my hand at building my own headphone amp. I'd like to make a bottlehead crack and a pocket class A, but before I do that I'd like to start with something cheaper/easier. I've never soldered or worked with electronics before, so I want to do something simple that won't...

Since upgrading, when I open Tidal none of my downloaded content is available. It says that I haven't downloaded any content. I have already switched my downloaded content storage to the SD card, and restarted my device. It is still not detecting any downloaded content. Is there a fix for this...

Yea, multiple user defined EQ is what I need. I would love to see that feature. It would also be good if I could name each user defined profile so I know which profile I created for which headphone.

Anyone know if there is a way to save different EQ profiles in the fiio music app? I'd like to be able to fine tune eq for different headphones without having to redo it every time I switch headphones.

I actually haven't had the chance to test the balanced output as I do not have balanced cables for any of my headphones yet, so I don't think I can help you. I can say though, I have a campfire comet and I love using it with the SE output on the Q1mkii, so perhaps our tastes differ.

Ok, so I don't want to pretend I can speak authoritatively about the difference between sources. Take my impressions with a grain of salt. By the way, so far I have tested it with my Hifiman re-600V2 iems single ended, as well as M9>fiio A5 amp>hd600 and beyer dt880 600ohm. I find that the bass...

Just got mine in the mail today, first impressions are very good! This is a big upgrade from my Cayin N3 both in terms of sound quality and features. I find that compared to the N3 the soundstage is more open, but at the same time it has a more "planted" sound, if that makes sense. Maybe its a...

Do you know if Fiio has stated any plans to add more codecs in future updates? Although the hardware is capable, there may be licensing issues. For AptX I'm pretty sure "receiver" is a different license than transmitter, incurring additional cost to the manufacturer. At least that's what Cayin...

Sorry if this has been answered, I couldn't find it. Will the M9 be able to receive bluetooth codecs other than sbc? I know it can transmit a bunch of codecs, but I am hoping to be able to use it as an LDAC or AptX receiver on occasion.

Thanks for the heads up, just ordered my M9 and a 400gb card for under $350! Been eyeing it since it was announced. Should be a nice upgrade from my Cayin N3, especially since I use Tidal. Hopefully it will stack well with my Fiio A5 to drive high impedance cans!

Any word on when this will be available on amazon in the US? Hopefully soon/by the holidays. Kinda weird that some online retailers I've never heard of have it in stock, but I can't find it on amazon, B and H photo, Adorama, or other big names that I trust to make it right should my purchase not...

Does the output impedance of the source matter? For example, my stereo receiver has a very high output impedance, in the tens of ohms at least, and I would like to use it with iems occasionally for silent tv watching. Will the earbuddy bring the output impedance down to an acceptable level for...

Will the BTR3 perform well used as a source for my car? Would I just turn the volume all the way up to get best performance in that scenario? Also, anyone know if it outputs at least 1vrms cleanly? Trying to decide if it would work for me. Thx

Hopefully I can live with it. In all other ways, this looks like a great upgrade from the n3. One other question, does it by chance do variable level line out? I need 1.3vrms or less for my car but prefer 1.5+ for all other situations.

I see you have the Cayin N3. That is my current dap and I notice the same thing, a lack of deep bass extension/rumble, when I compare it with my fiio q1mkii or my schiit modi2u/magni2u stack. In your opinion, how would the m9 compare?

What level signal will this put out in line out mode? Also, does it have true line out, ie. bypassing the headphone amp? Thinking about how this would stack with my fiio a5 to drive my sennheiser hd600s.

I think that article is somewhat misleading. From my understanding, the main issue with standard bluetooth audio is that it was never intended to carry music. When creating a lossy codec, designers consider psychoacoustics to determine what information can be discarded during the compression...

What I had asked Joe is whether or not the receiver is aptX or just standard bluetooth audio. The R3 definitely works as a receiver, but only standard BTA, no aptX. As a transmitter, it does aptX as advertised. The product overview is not as specific about this as it should be, in my opinion. I...

ahh, well thats too bad. It would have been a nice plus. Could this be resolved by a firmware update or is it more of a hardware or licensing issue? I'll probably still buy one! Wifi/Tidal is such a killer feature :) Now there's no reason for me to go android. Thanks.

Can anyone tell me whether this can receive BT-AptX? That would be a big plus for me. My Cayin N3 will transmit an AptX signal, but it will only receive standard bluetooth audio which is kinda a bummer. I'd love to have the ability to use it as an AptX dac/amp streaming from my phone. That way I...

How should I configure the Fiio Q1mkii for best line out performance? Which gain level/volume pot position will produce the cleanest signal? Also, it would be nice to know for reference the vrms in that configuration.
