The DUET is dead quite, even when I pair with the high sensitive Fitear. Cypher Labs have done a great job on it.

What's your source with it? And how is the SQ?

Anybody ever compare ak100+duet vs ak120..?? In term of sq which one is better..?

AK120 + DUET + LCD-X/Fitear 111
 
Great transparency and details. It improves the low range of F111. The amp section of AK120 is weak, it really needs to improve when pairing with high impedance headphone.

How come no one compares the Duet against RSA's SR-71B? Anyone owns both or has heard both can give some feedback?

I own Duet , rs 71 b and intruder
Rs 71 B
High : more crisp than Duet

Duet
Has better mid and bass

Duet is on par with Intruder
SQ is more balance than Rs 71 b
Rs 71 b overall sound thiner compare Duet and Intruder

IMO

I have pair. My LCD 2 rev 3 , my previous LCD 3 send LCD XC with class DB + Duet = SQ is excellent

ALO Rx 3 B has more power than Duet ,Duet has better synergy to my LCD

I think he 500 is ortho , should be very good pair with class DB + Duet

Rs 71 B pair with CL class DB to thin for your HE 500

Personally, I prefer the DUET much more than the RXMk3. It seems the only advantage of the RXMk3 compare to other portable amps is power. However, in order to get better sound quality and quite noise floor for IEMs, I will take the RXMk3 out of my list. Besides, the DUET has enough power to drive LCD series very well so you do not need a more-powerful portable amp to drive your HE500. If I need more powerful amp than the DUET, I would rather change to desktop setup.

Thanks for ur replies. Hope duet will do good job with he500. In some review shows the duet has not get enough soundstage.

[Cotnijoe]

The duet has wonderful soundstaging. at least in my book... 

 

[jaganeee]

Compared to rx mk3 b+

 

[jaganeee]

What is the sound signature of the duet ?

is it neutral.

 

[rudi0504]

Compared to rx mk3 b+

I don't have Rx 3 B+ , I have Rx 3B
I heard Rx 3 B+ m The advantage to Rx 3 B+ is Only better bass impact and bass body , the rest i prefer My Rx 3B has better clarity and better separation and better soundstage
Thats why i keep My Rx 3 B Not buy Rx 3 B+

For Me Duet has better SQ than My Rx 3 B, and The soundstage is on par With My Rx 3 B

IMO
