I have now listened more with the ALO the Continental V2, and I must conclude that the synergy with JH13 Pro is not good. Naim.F.C. also sent me an PM that the synergy "often depends very much of impedance ratings and differences between the amp and earphones. It could very well be that the Continental's ratings do not mix well with the J16 Pro, or that the Pico is simply warmer."
I sent an message to Alo about this and got this answer: "I am sorry you feel like the Pico is a better match for your IEMs. The V2 is more ment for larger full size headphones and is even stated as such on the product page. We do have a 30 day return policy but this is expired. If you would like to return it for a Rx2 however we can do this providing you pay for the shipping both ways."
I dont think this a good deal, and the 30 day return policy has by all means not expired (I recived the amp January 17th). But the most important, I am not sure if the RX2 is the best match for JH13 Pro. It doesnt say much about the sound character about the amp anywhere. I am looking for an amp with a warm sound signature, so the JH13 doesnt sound so bright, which I am kinda allergic to. I have done some researching and it seems that the warmer RSA Shadow probably would be a good match. So I will keep the Continental because I will probably one day try out larger headphones.
However, Ray Samuels doesnt respond to my mails in how I can buy the Shadow from him, so I think I will buy the Shadow from Addicted to audio in Australia instead, even though its a little more expensive there.
