That is a bummer HiFlight, I was hoping the Pro2 would have fixed more. However, mine doesn't have the delay issue between random tracks. Weird how yours does and mine doesn't.

Some of the issues that are present with the Pro2 have to do with the chip being used. If there is a change in the Chip, than the SQ is changed. These issues are being looked at.

There are improvements that are measurable over the Pro1. Now we need to look at the positive and also what can be changed for the Pro3!!

Development for the Pro2 was in a matter of a month. We are getting there....

Also, the studio might solve many problems as well. Originally it was capped at 10, now anyone can order..

Thx,
Craig

Order soon so I can get my order in!!

The more I think about it, all I am interested in is good sound. I don't use shuffle or any of the other options. I usually listen to an album in its entirety. Like I said, if it doesn't hiss, and the sound is great, I will be happy.

HiFlight, may I have your opinion on how much hiss is "normal"? Since you did nice comparison between PRO1 and PRO2, could you please let me know your opinion on hissing?

BTW, I also noticed those issues you mentioned in your post, but all of them are not of much concern to me. Only big issue would be boot time when in random mode (or generaly random mode problems). But I don't use this one. I prefer to listen to albums so after I start listening to something, there's no need for me to touch AMP3 for another hour or so.

All those imperfections are just minor issues when talking about SQ. I must admit that I like it. Only if there was not so much hiss...

So, I look at the bright side, but very much would like to clarify what is a normal level of hiss.

Anyone?

If it's built right you shouldn't hear ANY hiss. I use a 30ish year old desktop amp and it doesn't hiss at normal listening volume. My cheap computer speakers hiss though.

Hopefully Studio gets it right.

Hiss has not been an issue for me in either the Pro.1 or Pro.2.
I think that my mild tinnitis is right at the same frequency as hiss, so I don't notice it at all unless it is extreme, or in a different frequency range.

I don't want to come across as being overly harsh on the Pro.2, but excellent SQ notwithstanding, unless the issues I have encountered are addressed and corrected, the PRO will not be a major player in the DAP market.

I really hope that Hisoundaudio can engineers fixes for these issues.

HiFlight and Chef - thank you both for your answers. It's nothing like tinnitis - it's hissing. Present and audible. As I see it, it's definitely a technical issue and I'm sending my PRO2 for replacement. What to say.... bad luck.

Thanks again.

Has anyone else noticed that their Pro2 has much decreased volume than their Pro1? I'm not talking about the problems others have had with practically no volume. The volume seems normal, it's just that my normal listening volume on the Pro1 was 19 and on the Pro2 I have to turn it up to 26 to get roughly the same volume. I can turn the Pro2 up to 31 and still keep my phones in my ears. It's too loud to listen to, but it's not exactly painful. I could never have done that on the Pro1. I am using my Yuin PK1's. I don't need any extra volume for daily listening on my PK1's but if I got any phones with higher impedance I'm worried that I wouldn't hear much at all. Anyone else experiencing this or any suggestions for getting more volume out of the Pro2?

Thanks

Please remember that we, head-fi'ers are here is make this better...

I do know that these issues are being looked at very closely and there will be continue improvements as we move forward. IMO, still a fantastic sounding player that has some room for improvements.

All of the issues being discussed are being noted and I'm working with hisoundaudio on what can be done.

I must admit, in little over a month they were able to fix (not all issues), manufacture and in the customers hands in a VERY short time. We are continuing to make progress and the comments that this is not a marketable product in the mainstream retail is not important right now since we, enthusiast, look for sound as one of our primary focuses. Software can always be changed!!! Eventually this can be in retail stores. Which means all of us, who like to be ahead of the game, will start working at the Studio II once we have it in a few lucky listeners hands!!

I can't compare my Pro2 to a Pro1, because I only have the Pro2, but I was expecting alot more volume. I love the SQ, but it doesn't drive my ESW9 40ohm phones nearly as well as my Cowon D2. Does anyone else have both the D2 and the Pro2 that can confirm this comparison?

Craig, I think I would like a Studio 1, but I'm wondering if this will be just an improvement in SQ, or also an increase in mV output as well. I love the Pro2 SQ already, but it's not excactly a treat to use on a loud DC Metro train, unless I use IEM's. I prefer the sound with supra-aural 'phones, but my Pro2 doesn't have enough juice to compete well with the ambient noise of the train. As far as using it at home, it sounds AMAZING. Will the Studio 1 have more power?

Hello Ron Woody Craig and others,
First of all I want to thank and applaud Craig for the absolutely wonderful job that he has been doing in being the 'bridge'between head-fi and hisoundaudio and in promoting this player in general/providing customer service.
Second though I want to agree with Hiflight and disagree with Woody, in the past I too was all about sound and this still is the mos timportant factor but if features or reaction time are too far out of line this can be a defenite dealbreaker for me and I also think others. This does not mean that I think work on this product should be continued I think its wonderful I just want to emphasize that it is not ALL about sound while bing confident that things are biing done to solve some of the issues even if it might take longer.
As always, following everything with interest, oh yes an afterthought maybe we should create a new thread for the studio 1 once it is in peoples hands because the other amp3 threads are getting rather long.....
Greetings, Anouk,

Greetings, Anouk,
I would totally agree...

Being a software and a hardware guy, if the sound is not there, we, headfi'ers, would turn the other way. I think I can speak for almost everyone that has a player that we are now set on the sound, so lets start thinking about the playback!!!

The sound comes from years of experience that hisoundaudio has. There were many sacrifices made in order to have this sound. With some of the changes that listeners are mention would require a change in that sound. So decisions were made. The overall problem is being looked at, however I believe a step in the right direction.

Ok..simply put, we have sacrificed the "pretty girl" into the volcano, so our crops will be plentiful for years.

Check that off our list....Now onto SOFTWARE!!!!

Let me make sure I'm clear, I will do everything in my power to change the playback or software. Hisoundaudio clearly knows my opinion and I will continue to push as hard as I possibly can.

Oh BTW, thank you for your kind words, Anouk. You are a true patron and hopefully we can make you and others satisfied!!

The Studio will be here soon. So we have plenty of work ahead of us. Please continue to leave positive feedback as well as possible suggestions!!

Craig
