MiuAudio MRA DIY Headphone amp - Page 2
It works! and I seriously need to get a glue gun to make sure some stuff dont touch inside lol I do have slight issues with the gain switch though, the rear plate doesnt let the switch move to its proper hi gain position it seems :(
With my IE8:
It's not hissing which is a good sign :)
It seems to have slightly less bass than my govibe magnum (@ 0 bass)
doesnt feel as wide and doesnt go as high note.
The instruments are a bit further back with vocals up front. Can't hear as much small details.
With my HD600:
300ohms is too much for it to handle at low gain.On high gain... lack of bass prob from the lack of power. Vocals are up front and a bit too high pitched.
The interconnect I am using is a DIY LOD with rectangular solid core copper wires which may not exactly be the best reference interconnect cuz it pulls the soundstage quite far
Overall, quite a good amp for its price! and quite fun to build too. my magnum costed 5~ times as much LOL
I don't recommend driving 300ohms on it though. It actually have a bit more oomph than my magnum on high gain but it doesnt sound right when i compare it to my PA-10 stationary amp
and hopefully im doing my "review" right hehe
as for batteries, don't know yet, running on alkaline 9v, only used it for an hr or 2 so far
nope didnt solder too high, it works fine now after some slight adjustments and making sure that the backplate isnt touching the switch.
but yeah the switch has to sit flat on the pcb or else there isnt enough clearance and gotta make sure the pcb board doesnt flex upwards because that too will make the switch touch the top of the gain hole
