So, I'm looking for that perfect amp... - Page 33

post #481 of 915
I'm happy with my PB2s on SE for now and based off some comments I had from some one who also has the PB2s balanced the change isn't a night and day thing and you'll be hard pressed picking it in blind tests. I'll stick with SE for now until I itch for an upgrade. Plus I got enough op-amps to roll with

I'm not yet try the balanced since I kind of busy, don't have much time to build my own balanced cable :D.

 

I plan to build universal cable with my Cardas 4x24 cable, it will be used with all of my headphones and iems :D

This thread has become silent the past few days. I just got a Leckerton UHA-4 with OPA627 opamp. Not as big as I thought it is. Just a hair wider than the DX50 and about half an inch shorter. Fits nicely at the bottom of DX50 with a low-profile dual lock.

 

Quite the opposite experience portability-wise this past few weeks with the O2. I can easily hanle it in one hand. I'll give it a full week of test drive and see hoe it compares with O2.

So has anybody purchased from this Chinese i-vendor?  I am thinking of buying the PB2 for my dx50 from these guys as it`s still out of stock at iBasso.....

Reputable?

Did you experience an immediate improvement in SQ when paring UHA-4 with DX50?

I am trying to use UHA-4 for a week before I do some comparison. My initial impression compared to O2 however is that UHA-4 appears to be extracting more details but sacrifices the lows/bass.

I don't know if this will change after some burn in time but definitely noticeable is the decrease in bass impact compared to O2. But I defintely hear minute details which is very faint on O2 and the mids seems to move a bit forward. The details are clear even at lower volume compared to O2.

I really like the digital volume control. Each flick is very precise. I can listen to a lower volume level without noticeable decrese in detail resolution.

I don't notice any impact with xfeed on. maybe I need to try more tracks/genre. This amp is pretty quiet. No hiss at all. It also appears to decrease the hiss effect on some tracks known to have hiss in the background

I just hope the bass impact comes back after some burn in time with UHA-4. Only tried JH16. I still have to try other IEMs. My hands are so full right now with the gears I have and combinations to test.


UPDATE:

The UHA-4 has no problem properly driving a 600-ohm Beyerdynamic T1 to a very loud volume.

I gave up my hunt for the perfect tiny IC and decided to make one myself. Two angled Neutrik 3.5mm plugs sans barrel, Mogami 2893 wires. Finally something compact enough for my tastes :)

 

Wires soldered - I had forgotten how annoying it is to work with such short lengths of wire!

 

Test drive, yup it works perfectly.

 

Heatshrink fitted, elbows ready for a drop of super glue.

 

All done! 

 

 

 

 

 

Quite a bit more compact than the old one, I'd say!

That looks awesome, wow the amount of precise hand work. Now you got me thinking maybe I should have used my two neutrik plugs just as you did. I am impressed with your end result, very encouraging. I might give it a try if I ever want to rewire couple of neutrik connectors. smily_headphones1.gif

Thanks a lot, to the both of you! :smile:

 

Nope, not going to make these for others! Took a full week with the parts lying around before I could find the time to just make this one for myself. I used to make a few cables for local Head-Fi'ers but I had to call the quits as I simply didn't have the spare time needed. Now I'd much rather just document the things I make for myself and teach others how to make their own.

Yay!, finally. looking great!

Goes to show finding the best IC is the one you make yourself. I've been contemplating about making one myself. However, I don't have my tools, let alone finding the extra time. Looking at my snake-like IC still am looking out for a better IC

Yeah I just got fed up hunting for that perfect cable (since Headstage won't sell theirs separately) so I finally found the time to fire up the soldering iron. I have an idea for an even lower profile version but that would require me to make an epoxy body for it so that's a job for another weekend.

Oh man, that thing is P.E.R.F.E.C.T.    Why are these not commercially available?    
Nice work!
