Co się dzieje, nie widzę wątku o nowym przenośnym wzmacniaczu
Dla rozpoczęcia dyskusji wrzucam swoje review z hedfaja, w skrócie: bardzo, bardzo polecam i warto kupić tak długo jak mamy grajek obsługujący AptX.
Mam też porównanie generalnie z każdym przenośnym wzmacniaczem BT jaki jest dostępny na rynku - bo pracowicie sobie je kupowałem u nas albo za granicą i szukałem tego najlepszego. Jedynym wyjątkiem jest Noble BTW bo jak przeczytałem w pierwszych reckach że ma bass rolloff silny to od razu skreśliłem.
Jeśli natomiast grajek nie obsługuje AptX to zakup nie ma IMHO sensu bo dźwięk przez zwykłe SBC jest płaski jak blat.
Nie wiem jak z AAC (XB10 go obsługuje) bo nie używam nic jabłkowego, ale z tego co mi sieć podpowiada APTX>AAC>SBC więc jeśli masz iPhone to przetestuj przed zakupem bo może nie będzie tak źle.
W każdym razie na AptX jest świetnie i z komputera i z telefonów.
A tutaj materiał który napisałem tam:
Sources: LG G3, Samsung Galaxy S6 Edge + (both Apt-X capable) + Neutron Player, tracks: FLAC and MP3 320kbps, some 128kbps files and mkv movies in Archos. Devices to compare: AudioTechnica AT-PHA50BT, AudioQuest Dragonfly Red and Chord Mojo (last two just for fun). Headphones: IE800. Build quality vs AT More or less the same, with slight edge for AudioTechnica - black and silver are looking more elegant. The clip on XB seems to be better but as I've found this morning its more or less as useless as one found in AT. Good clip should be working like the ones on Samsung devices (Link Level) or Soundblaster E3. Looks like I'll have to use some self adhesive velcro on the back of the XB10 same as I used on AudioTechnica. XB10 is a tad bit heavier - we'll see if that means better battery life. Interface vs AT As I've already found out the buttons placing is at least strange. IMHO the next/prev buttons should be placed on faceplate along with the volume controls. Placing them on the side and volumne on the front is not very handy. Also, volume control using buttons instead some rotary element is in my opinion not the best idea. In general, AT wins the interface part hands down, there is no way to press something by accident and if you intend to press something on purpose you can do this without looking at the device. I have big hands and I always have to look at the XB10 to see if I'm changing volume or pausing track. But if your fingers are smaller or I don't know, more "sensitive" - YMMV. SQ Bass: deep bass going strong and smooth to the sub level, really enyojable with IE800. No muddy midbass here, everything is audible and hummmms! (I'm a kind of basshead myself) Mids: clear but a little distant, nothing good or bad to write here. Which should be taken as a kind of compliment really as there is nothing wrong with them. Treble: clear, strong but without siblance - just the way I like them Dynamics: good range, everything sounds engaging - no flat, dull tracks with this device. Soundstage: OK. Not congested, not very wide. If I'd be forced to choose I'd say it is a little bit on the small side. Acceptable for my taste but I think that just barely. Definetely wider than the soundstage of Soundblaster E3 which was way to small for me to enjoy my music. Others: No hiss whatsoever with 24ohms IE800 (them being very sensitive). Clear, black and empty background. Maximum volume levels with IE800 are ok, the max value is over my tolerance level but I was expecting it to be even higher. I will do some more testing here because I'm surprised that though they surpass my comfort zone I think that they still should be louder. SQ vs AT Bass: XB goes a tad bit lower than AT. Small difference but noticeable if your headphones are up to it. Mids: AT mids, vocals especially, are closer and a bit more engaging. Treble: more or less the same with slight edge to XB10 Dynamics: XB10 has more foot tapping effect, AT sometimes can get lost in congested parts of the track. Soundstage: this one goes to the AT. This device has very, very wide soundstage, almost as wide as DACs like DragonFly or even Mojo. A winner here. Others: AT hisses, just barely noticeable, on IE800. On IE8 hissing had to be supressed by 30ohm impedance adaptor. AT is also louder than XB10. Display - AT has a nice one, though I've never really used it. More like a eye catcher for strangers when commuting. What I did not test: balanced output, battery life (yet to be determined), BT range (as I wear the device on me when my phone is in my pocket), pairing with two devices (I dont expect any trouble here, as this is something that my 2009 mono HM1200 handles well) Price: AT-PHA50BT can be purchased on Amazon for ~100$ (new, unopened etc) while XB10 is available for 189$ (I will not comment on some amazon 240$ offers) I think that if you already have AudioTechnica you may think twice about upgrading it as it has outstanding price to value ratio. If you think about buying some portable headphone amp, consider Dragonfly Red - for almost the same price DragonFly's SQ is ubeatable, however, it is not wireless - but almost as portable as XB10. But if you - like me - see that this kind of device is a must have, just try before you buy because like me you may end up with one in your pocket
