Portable Headphone Amplifier "WAGNUS Bialbero Epsilon S" impression and appreciation thread

[rudi0504]

Did you guys notice a different with the burning in of your amp? Mine has now 30 hours can I cannot tell any change.

My Friend has Opened his Wagnus Epsilon, Insite have 8 Black Gates resistor

Black Gates resistors
Need more to Burn In

Sounds like Wagnus has too much gain for sensitive headphones.  Adding impedance to fix this isn't a good option for multi-BA iems as it has crossovers full of resistance, capacitance, and inductance.  It will shift the crossovers, which not what you want.

Pak Rudi is very informative.

The size of Wagnus is fine with me as I do most of my listening at home. When I am out, N6, DX90 or iphone4 are my portables.
IIRC, its size is similar to Triad L3 but much lighter.

@audionewbi, I tested the Fujistsu Eneloop 2450mAh and it has a life span of 6hrs 15mins versus Sanyo Eneloop 1900mAh 5hrs 30mins.
Setup : laptop>Meridian Explorer>Wagnus>VE6x2.
Albums or tracks used: All Led Zeppelin.
To my ears, Fujitsu has better SQ than Sanyo. Recommended to try.
And regardless of mAh, we should be good as long as it gives that extra mileage.

Btw, did a couple of emails with Dimitri, and his info' suggest user to use Panasonic Eneloop for the preamp. Will be getting some of these (2450mAh) and test it out next week.

The best source for wagnus for me so far are all my apple devices. I am interested to purchase the meridian director I hope someone can get to try it.

To my ears wagnus shines with dynamic based gears.

I also own a nos of Apple devices. When i used Nano 5th G with Wagnus, it gives or brings to me that wonderful tight sub basslines effortlessly and not neglecting the upper frequencies.

Not sure whether the audio shop that I used to chill out on Sat has the director- not been there for many weeks now. Will likely to go down this Sat and have a look and also to test out the Alo Key which uses PCM5102A chips. Meridan uses PCM5102 without A, so am curious to compare the difference in their implementations.

I've noticed that wagnus likes to have low gain input, something between 0.2 to 0.5 vrm. Anything more seems to not work well with it.

 

[SilverEars]

This is because it has high gain. LO standard is 2vrms. Sounds like its a $1k piece of doo doo. No gain adjustable? Youre locked into using cans for these. No iems. Its sad, my Vorzuge pure ii half the cost and rediculously transparent ha 3 gain levels.

How does CD900ST pairs with wagnus?

 

[audionewbi]

Please dont hold me accountable but for those who are interested I heard that apple is using eneloop batteries for their charger they use.
 
It comes with 6 batteries and a charger and it is much cheaper than other options.

I got the information The best battery for Wagnus are :

Sanyo Eneloop XX black color 2550 mAh
Panasonic Eneloop Pro black color 2550 mAh

If 1,2 v and 1900 mAh is like the white Eneloop is not so good for Wagnus

Here is the picture :

Mid : sweeter than direct Wagnus , i can feel Tube sounding midrange , My LCD 3 F mid
More creamy , The clarity remain
Bass : has better bass impact and now full body
Separation : is about same very Good
Soundstage : i feel direct Wagnus is wider but the Depth is better now

Overall :
With additional Tube pre amp Valvora i feel The Power increase quiet a Lot
AK 240 at 60
I turn the volume at 10 O clock sound so Power full
Sound character is different , now is more to Tube sounding amp , With excellent mid , and The bass more weight .
Direct Wagnus The High is brighter , now The High is more natural and neutral

I Will update more After Burn In
