how about the stock earbuds + Amp3? how does it compare with PFE + Amp3 combo? if you say it's way better, I must grab an Amp3 Pro2 right now before it's too late.

IMHO, the PAA-1 included buds blow the PFEs out of the water, not only in quality of sound, but also in quality of construction.

The more playtime that is accumulated on the AMP3/PAA-1 combo, the better they sound together.

Wow! I haven't been listening to the PAA-1 as I need the IEM isolation (both ways) and the Denon C710 and Mingo WM2 sound so so good with the AMP3, but now I need to try. I really did like the PFE, but haven't heard it in 5-6 months.

I am used to the earbud than not the IEM now after near one week of AMP3/PAA1 combo listening.

I feel the earbud is more comfortable than the IEMs to my ear. And the perfect matching of AMP3/PAA1 can turn out enough details and musical tunes to off set the environment noise when on the bus or train.

I certainly agree with this.. no cable issues or fractures and a much more balanced sound

The AMP3 is unique in that it has been designed around the ear bud supplied , this is not just any bud but one specifically designed for the player.

Agree, which came first egg or chicken, but The AMP3 and the PAA-1 are both unique and each of them also sounds so very exquisite with other combinations as well...

so what Design Circuit did other DAPs use? (cowon, ipod, creative, samsung, etc)

I agree with you, The character of Class A circuit is " power hungry". in some of the home amplifiers with class A circuit design, it will consume more than 1000 wat electric power.

But as the portable gears only have a small battery to suplly the power. So how to save the power consumptioin is every audio maker's priority designing task.

So almost no other rest DAP makers dare to apply the class A circuit design even though they know the class A circuit is the best one for compensating the cold and dry digital sound signatuer.

The more amazing, even AMP3 applying the most power consumption circuit, it still can have 100 hours playing time. To my experience, if AMP3 applying class D circuit, it can playing 300 hours!!!!!

I believe they used Class D, but of course I'm not sure. Class A is a linear circuit often used with tube amps as far as I know..

Sorry this part I'm copiying from FOEVERFI"s answer to my question..

Thanks ron for this great fair and honest review!
Greetings, Anouk,

In my many years of listening experience, AMP3 should be used in pure Class A amplifier circuit!

1, it is also very warm and the sound is very full-bodied, while rich in detail and also has a very powerful dynamic, this trait in common DAP (such as the IPOD, SANDISK) is certainly not heard it, it exists only in high-fidelity Pure Class A circuit.

2, I took the same first caballe singing "Grandes Heroines Lyriques" in AMP3 and the home in Pass ＋Focal mini utopia of pure A class Hi-end systems were repeated comparison and found that their voices are surprisingly similar qualities! caballe voice rounded out sweet but also just right to express an appropriate degree of heroism, it sounds, very enjoyable, the music and the instrument separation is very meticulous, and orchestral sounds of the wooden pipe is particularly the sweet, the sound of the gloss and brightness is so just right, wind blowing in a circular shape is so true, even if the flow from the highest point we do not think there is a trace of reluctance, but also people think there are many margin, this instrument can express the characteristics of degree of texture or even warm I also only in the most high-end pure Class A sound system in the taste, but the AMP3 have this trait!

3, I like singing in a choir once spent a period of time, so I am solo and chorus are very sensitive, there is a singing technique is able to explain the nature of a pure A class circuit, we sing when asked to do every note must be sent to maintain the same energy level voice control, even in the weakest sound at too. Using AMP3 listening Carreras's "South American mass", it is perfectly expressed this only in pure class A circuit can be Jinxian advantage Carreras bright high-pitched voice can make your with emotional pitch with him to climb in a warm, but there is the need for a large number of songs in a rich atmosphere of the chest supported damper handle is beautiful and moved people to tears, and only pure Class A circuit in order to provide the same at any time, a powerful energy the performance of the supply of these sometimes as low as the Ministry of the details can not be heard in the dark.

Thanks hiflight for this great fair and honest review!thanks hisoundaudio able to provide such a good product, I must say, can buy DAP have such a perfect sound quality of all the happiness of the people who love music!

Yes ,I second that comment, perfect sound quality!!

X 3. I would like to add in my experience on the chorus with AMP3. I have never get the details of chorus with the other DAPs. by the rest DAPs, the chorus seems there is only one signer here and the stage is very narrow.

With AMP3 to listen the chorus is really a bliss. The sound stage become larger with deeper image. the signers are in a very layer gestures and their position line is full of shape.

It is very amazing that AMP3 can exactly portrait the details in both low and peak passage!! ----- this is the advantage of Class A circuit amp. it has a transient controlling strength.

Maybe, Class A circuit amp will be the standard on hi end DAP in the future.

It is my opinion that many of the innovations which are being done by Hi sound will become standard in players of the future, Class A amp, more than 100 hours playing time , integrated buds and players which are designed for the appreciation of music, at least I hope they will.
