The low gain on my 627x is weak , is it normal ? the amp is paired with my Ibasso DX50 , the headphone : Denon AH-D7100

I easily pair my original 627 with the HD800 at low gain, normal listening at 6 o'clock volume knob. I don't think the D7100 are more difficult to drive.

What is your player ? I think that come to my DX50 .

It's the DX50 , on my Hifiman HM801 , that's totally different in low gain setting ,volume knob at 4 .5 o'clock ;the sound is very loud .

I use it with a Dacport LX that by default is set at max volume (no vol control)
post #216 of 379

you should set the volume of the DX50 to 245~255 when using the LO ;)

post #217 of 379

I doubt now that the LO of the DX50 is not a true LO , because the internal amp can control it .

it's no doubt a LO. The output control is controlled by the DAC

 

the explanation is found at the DX50 thread, The level control is good IMO, I pair my 627 to the DX100. If I set the LO to 255 it gets too loud even adjusting the 627 as fine as I can. so you can get finer control, which is good for IEMs. 

 

I believe the sweet spot of the 627 is at 10-11 o'clock, so I just adjust the LO output of the DX100. Same case with the DX50.

 

*don't worry lowering the LO, it is bit-perfect at any level :)

I am searching (where to buy) for rubber bands that is enough large to attach the 627x on my DX50 or Hifiman HM801 , thanks in advance .

I suggest to use 3M dual lock, either low profile, or the standard one if you plan to use microsd to sd converter to allow the use of 128gb Sd cards wink.gif

By the way, can you post pictures of your DX50 / 627x rig?_:)
post #222 of 379
OK thanks for the 3m dual lock. , i don't have pictures of my DX50 , but you can have a lot from the net .

Did anyone see that a Portaphile 627 micro was coming out? A 627 in a smaller casing. Has it been mentioned on the thread?
post #224 of 379
Besides, anyone compare the 627 to the Vorzamp Pure II?

Not in this but I did mention it in the other thread. I am still uncertain would the reduction in size mean a compromise in sound? A smaller 627 is truly welcome and the battery hour is just long enough for my trip to and from work but on the other hand the old 627 is not that much larger.
