No, I did not try to contact Robert, since then.

Hello all I have been demoing portable amps for the past seven years with the goal of improving the over all sound coming from my Various DAPs (X3,DX100,DX50). I have read how an amp can help but after demoing various top end amps I didnt hear any great improvements from my IEMS ( customs and universals) but I did get a sense of added power.  When I met an owner of a audio shop to demo his IEM he had an amp and I quickly noticed how small it was. It was so thin and tiny so I asked him if I can see it and I notice how well made it was and that it had a lot of features that other amps did not have even though those amps were much bigger. I asked if I could try his amp with my DAP and my IEM with my Favorite tracks. Pow so much improvement. Sound stage wider bass deeper treble clearer. I was sold and I said I want it and I want it now. I offered to buy his IEM if I can also get that amp. He said this amp takes a long time to get maybe it will take 3 months so I said I will buy his used amp at retail cost. He agreed and I bought it and I love it. I believe it is the 5p model and it does everything I want from an amp and it improves all my IEMs such as; JH Audio 13,16, H8P, 846,IM70, UK10 and my Fav the Z5. I love it so much I ordered the new Arrow eventhough I have not demoed it and I read it might have a different sound signature.

ain't it though! yes it is just like that! a must have, oh so well worth any wait! I am so in love with my 5N!, I have the power board, but I just can't get over it ti try out the P board!
 
welcome aboard JW55! Robert like I've said is truly an artist, and he puts out works of audio art! he packs alot into a tiny package and marries it all together, bringing audio bliss to my ears!

Anderoan - I agree and I want another one.

Hey Anderoan, so you currently are you using the 5N but have the P board separately? I don't think there's a difference in sound between them, the P board can just add extra bass so you shouldn't need to be hesitant to switch. The sound itself shouldn't change

I have ordered an 5N in february, I have received an email from Robert that said he is improving the circuit to deliver in April a version 5NX. I have also received an information from Robert about the improvement of the output chip of the 5TX for a better soundstage.

I hope that he will be happy with the latest version. It's good to deliver a better amp but I also would like to receive one !

Lol yeah ordered a 5TX in January, still waiting..
 
A little bit off topic, are you happy with you AK100II? I'm considering either that (because it has balanced out), or a much cheaper X5/DX90.. Heard that the DX90 was better than the older AK's so I'm hesitant to spend so much..

a funny thing about that thread ... REALLY funny !! ... is that it started from about 5 years now .... and it is only about 216 pages now ! .. though it is the most feature packed quality amp i've ever seen .... seems like people are just getting it ... enjoying it ... and just listening and listening ... no mush talk at all ... they are just enjoy it and when a newer version appear they upgrade to the newer one    !!!

So true even though this amp cannot be bought in any audio store in the whole world,and most people want to go to a store and get what they want right now or get on the internet and receive it within a week people who heard it are waiting for it, waiting months for it.

I have the DX90, the AK sounds better (detailled) and have a nice UI than the DX90. But as you say is't cheaper.
I'm very happy with my gear AK (in line out mode) the arrow G2 and the HD800. I don't expect a big step in sound with my future 5NX but Robert ever surprise me.

Thanks man. Does balanced make a big difference? And more importantly, do you think its worth the extra cost compared to the DX90?

Just received update from Robert: 
 
"Just a short update regarding the Arrow 5TX…
 
As there was some delay with the aluminium front panels I decided to use the time to improve the amp. I wasn’t very happy with the solution I wanted to ship in February/March. Simply speaking I changed the output from AC- to DC-coupled (without output caps). This improves the soundage on very low impedance IEMs. I had to do some research as the power adaption works differently. So it came up to this 2 month delay. I apologize for letting you wait. I will receive the new circuit boards this week and then start the assembly…"

fyi, i wrote inquiring about different models of 5.  received a reply today:
 
The 5NX will be neutral sounding with a different opamp inside the amp. The 5TX is a little warm sounding. But its still in development and will be released later.
