Still no new for my Roxanne yet :(. I had got my player. Surprising that the volume knob stay less then 10/60 from SR-71B and it's very loud and the sound is amazing.

I think my SR71B are deffective, I just found out when I use ak120 since the volume are so low. I turned the knob all the way down to 0 then slowly turn it up and I notice the sound come from left 1st, right is totally silent. But when the volume hit certain point and it back to normal and the volume is balance on both and right. I swap with different player snd use se out problem remain the same.

Have you flipped the switch on the back of the amp towards the balanced connector?

SR-71B & the Intruder are balanced left to right channel ONLY ONLY through the balanced output plug.

Using SE output you might have imbalance between left & right channel.

The amp was meant to use the balanced output. Please do not touch the balanced knob adjustment as you will through off the balanced left & right channel when the amp is used with balanced headphones.

I'm using balanced setup from player to amp but SE to phone maybe that the reason. Also tried SE from player to amp. Don't have the balance cable yet.

now i tried using jh16 with my sr-71b line out from my fiio x3, surprisingly with sr-71b, the amount of bass is greatly reduced, without it, the bass from jh16 is more, maybe because my jh16 is right out the box and i had not used my sr-71b a lot yet

Please wait till you get your balanced cables & you will be very happy.

In fact, i'm quite happy with it :P. The problem don't disturb me at all because it only happen at very low volume like 2/60, once it hit 3/60 it become normal.

Lots of photo's out there already but yeah, more is good... how are you now thinking of stacking them?

post #1167 of 1192


The ic cable cause difficulty to fit into pocket and the thickness as well since it close to 40mm thick.
post #1168 of 1192

.... so the plug protrudes by 4cm. Ok.

 

A good thing about TRRS though is that if you use an amp where the input is somewhere else you can rotate the plug to face the correct direction, more cable stress but its a good option, with a Lemo you might be stuck with it facing downward as I think the pins prevent the plug from facing any other direction other than down. Some ALO and RSA have the input at the top of the amp for example, next to the volume knob so the cable would have to face the other direction or you'd have to turn the amp upside down but the volume knob would be the wrong way round.

Suppose if its single ended it might not matter but in general.

No the plug protrude about 17mm, overall size about 105x85mmx40mm. Yeah single end would be easier.
