My one legged puppy is blind and the only thing that brings him joy are tube pre-amps to keep him warm during the freezing winter.

[@CustomCans]

Even though you are breaking the rules with that totally real sob story.. I will stick your name in the hat any way... it is Christmas after all ;) Good luck

[@josebarron4626]

Was pulled here from the FB page, Nice amp!

[@CustomCans]

My cunning ploy worked ... Would you like me to stick your name in the hat for the give away?

[@savagej4y241]

Your shop's customizations of my SR325X cans are finally keeping them going past the 3-4 month mark! Maybe I just got unlucky twice, but the standard Grado non-detachable cable connection was a severe design flaw leading to product failure twice well before the initial 1-year manufacturer's warranty was completed. They also revealed strengths and weaknesses in my setup, prompting some changes. Cheers and have a good one!

[@CustomCans]

Thanks ;)

[@davidwilkins7289]

Luckily, both my legs still attached and working fine for me. You make really good review videos, please keep them coming. I would love a Fosi preamp. I hope to be in the draw. Beyerdynamics DT990 Pro V3 mod kit still sounds great.

Valves are from the good old days when my dad would send me to the radio shop to get a new one for the tv or the wireless, the fibre back was often off the back of the tv so we could look for the valve that was not glowing, all so that we could watch Z cars on the tiny screen, i don't think the passion for the valve sound will ever die out

[@CustomCans]

Thinking about it TVs must have been incredible pieces of technology when they cable out. I remember thinking CDs were crazy - lasers and digital to analogue converters in the early 80s seemed ahead of it's time

[@PijusB]

I had one of those Fosi preamps, it was a nice little thing

[@CustomCans]

Yeh it's a nice little unit

[@FunFiEmpire]

Got both legs, so don't add me to the competition, just wanted to say I loved the video, especially the medieval torture XS . Here's to the algorithm!

[@CustomCans]

Praise the all knowing algorithm ... Thanks for watching

[@nomdeploom5707]

I was expecting it to be more spendy but that's a pretty reasonable price. Warm nips at hand for when the misses is away too! Win-Win.

[@CustomCans]

Lol ;)

[@fkitmcghee1773]

There's something very cool about such very analogy stuff like valves.

[@CustomCans]

yes - they do have the cool factor

[@MrFabioxz]

Dude thanks for the review and you honesty as usual!

[@CustomCans]

No problem Chap

[@gelderlandproduction]

Exactly!!!!! Remember to have fun!!!!

It is the most important thing ;)

[@robandrews9826]

Getting my 1st set of audio equipment for christmas!

[@CustomCans]

Nice... welcome to the hobby ;)

[@avasolaris1]

Good job as always. An even better job if you send that amp all the way to Australia. Royal mail will love you.

[@CustomCans]

Lol - I give close to £3000 a month to royal mail so they had better love me ;) I will stick your name in the hat

[@Superbellsmell]

Recently found your videos after getting the Edition XS and looking to get the mod kit for it! I think this amp will go nicely :P

[@CustomCans]

I will stick your name in the hat then

[@nwooley83]

Love the way you did the review on this. I am just now looking at getting my first dac and possible amp combo to power some decent studio monitor speakers I have and AKG headphones. I will definitely be checking out more of your videos. And if shipping to the US is okay and the entries are still open I would love to be tossed in the hat.

[@CustomCans]

Yeh - I think we are picking a name tomorrow so I will stick your name in the hat

[@nwooley83]

@CustomCans awesome, thank you. Really enjoying your videos and definitely eyeing some of those cans you have on the site for a splurge spend this spring when bills go back down from the cold

[@4everidle]

If you want to send that amp my way I will happily adopt it. I've been drooling over Fosi's amps for a while. BTW, I purchased your HE400SE replacement grills a few months ago and they are fantastic. Your jumper is also great.

[@CustomCans]

I will stick your name in the hat ;)

[@truckerallikatuk]

I'd love the headphone amp. Hopefully it's pair nicely with my HE400se that have the supergrills and the strap mod. My supply of old stereo amps is running low, and I need to summon up the energy to recap one.

[@CustomCans]

Yeh it would match nicely with the HE400se .. I will stick your name in the hat

[@satyavratadas1640]

I could use some warmth this season!

[@CustomCans]

I will stick your name in the hat ;)

[@QOTSAPT]

I really need that amplifier just because.

[@CustomCans]

Consider your name placed securely in the hat

[@116RonH]

When I hear Valve I think of water valves, engine valves, gas valves, the game company (Valve Corp), etc. But Vacuum tubes only really remind me of one thing, so I like to call them that. Fosi makes lots of good products, and I like that they try to make things affordable too. I'd love to have one.

[@CustomCans]

I will stick your name in the hat

[@frederf69]

Unusual for Fosi to not include a remote. Nice lil d class amp for the dough though. Nice to see the inners, tanks.

[@CustomCans]

Glad you enjoyed it :)

[@mangomatt1]

Love to be in the draw - but it would mean postage all the way to Australia (pretty please). I always enjoy the Custom Can videos and have purchased some custom kits for Beyerdynamic DT 770 from your excellent on-line shop. Cheers!

[@CustomCans]

Your name is in the hat ;) we ship stuff all over the world and Australia is one of the easier countries to get stuff to

[@geardawg1358]

Valves, Tubes, lamps, not sure on the lamp part, but all the same, you really should give a try to a proper valve headphone amp, the little buffer variety are OK to play with, have a few myself, but they are nothing like a proper tube amp. Xduo make a couple OTL head amps, of course there are better, but they offer a good starting point for a proper representation of the sound! BTW, love your vids! Don't need the little fellow, no sob story from me but I'm sure someone will enjoy!!

[@CustomCans]

Yeh we had an Xduo amp in for us to make some custom cables for them but I did not get to have a go in it. I may try to get one once I have saved up some pennies after christmas

[@Rarebush]

Go on then. Throw me into the ring. I appreciate the content.

[@CustomCans]

[@hugomottet1516]

I'm building a pair of speakers and I don't have an amp yet... I'm looking at these classD amps and I'd be very happy to win one !

[@CustomCans]

Will be reviewing a couple of them soon I will be giving one of them away so keep your eyes peeled

[@davidpeachey1837]

I like it, cool dac amp. Does the volume control and/or tone controls also control the RCA output or does it output at a fixed level?

[@CustomCans]

I did not play with the tone controls but the volume does vary the output from the RCAs - you have to turn it up to close to max to get line level out of it. I will stick your name in the hat

[@JustineCoudbit]

Hello, any opinion on the latest Sennheiser hd 490 pro and the use of its software that comes with it? Maybe a full test planned soon?

[@CustomCans]

I did a video on the HD490 when they 1st came out but did not play with the software

[@JustineCoudbit]

@@CustomCans ok thanks, you should make a video on "how to install and use the software provided" with this headset, because I haven't found anything serious on youtube

I'd love this. just using a soundcard in my PC rn. would there be a way to *reduce* the warmth in sound if I dont enjoy it with my headphones personally?

[@CustomCans]

I will stick you name in the hat but I think warmth is just the way it is with velves / tubes

[@DeBloba]

My leg fell off and the valve nipples are the only thing that would fit my new cyborg aesthetics!

hmmm... my current DAC is still going strong but if it ever dies I might have to pick these up.

Im interested in one of these the warmth and tone controls. How well do those work with headphones?

[@CustomCans]

I tried quite a few headphones on it and it worked nicely and sounded really good.

[@arimanwd]

@CustomCans nice. Is it able to drive large planars like the Arya or would you recommend feeding it to a more powerful amp for those?

Valve Life…. For those who know, know… ✌️❤️

[@Cp48533]

I just lost my lego house in a trip and fall situation (probably because i don’t have both legs), the amp will help me rebuild. I will use it as a brick that i can plug into for music. Hopefully it can withstand the weight of the new lego house. 😅 I swear it’s not a sob story. Just a bit of fun

[@CustomCans]

It is pretty sturdy and if you modify the house do there are holes in the bottom vor the valves will keep the lego occupants toasty and warm. I will stick your name in the hat

[@marijndegezelle3819]

the "tubes" are just used for a buffer like a 6J1 the is commonly used in this one 6A2, but there not doing much. just giving some 2nd harmics, Since that higher it will more sound more warmer to the human ear. a trasistor can sound very shill and cold since they have a lessen 2nd harmonics. But yea there not doing much there more for show. I have build my own my own OTL tube amps for higher impendance headphone (let say higher then 150 ohm( planar won't work)

[@CustomCans]

I thought that may be the case

[@marijndegezelle3819]

@@CustomCans what some even do it just not use them, a friend of mine came in to roll tubes but they worked without the tubes. So what the company had done was just hooked up the filamant voltage(+-6.3v nominal) hens the the first number 6. but yea they didn't even bother with the cathode anode and screengrid. a tube has just more distorion in general but that can makes them so pleasing to listen to since it give them a "natrual timbre" then a "clinical" one that you can have on tranny's specaily the really tranny's from the 60's are harsh sounding. sorry fo going down the rabit hole :)
