Hey there!
Sorry,I have been pretty busy lately and didn´t find the time to give you an update on my Stepdance impressions.But I have read every post and I think maybe I can be of a little help here and there,at least I hope so
For the power consumption matter:I would suggest to everyone to get the recharchable batteries with the highest possible mAh´s.I do not think you can hear the difference between 8.4 and 9.6 batteries.I have a PSU where I can adjust the voltage between 6 and 15V and I do not hear any difference between the two settings I have used so far (12 and 15V) ,except that 12V sounds much cleaner,but this is related to my cheap switching type PSU.By the way,thanks for the advices on PSUs and what I could do to make mine sound better.But I have to say,the PSU was great for burning in,but usually I will use this on the road so a expensive PSU is not what I am looking for.But I will modify my cheap one for a cleaner output.
Then there was this discussion if the sound signature changes during burn-in.And I can tell you:IT DOES!Interestingly the sound was screw*** amazing right out of the box,I fell in love instantly.Then the sound changed,on the extreme ends for the better,the mids were not as good as in the beginning.I think the signature changes most between 20 and 100 hours of burn-in.After that the changes are only very small.But now,I think there are about 300 hours of burn-in on mine,the sound has settled I guess.And what can I say:It is incredible!And for those of you who have read my previous posts,I still don´t like my Shures as much as before.They are sounding better then without the Stepdance,but I really am into full-size cans now.I think the only problem so far was that I didn´t have the source to drive them adequatly.The AKG are so much fun with my setup,and I think I will buy a pair of Beyerdynamic DT990 for listening to "popier" sound.
By the way,sometimes I am a roady for a Band (I do their merchandise) and they all have pretty good IEMs and of course they are interested in good sound.But none of them had any experience with portable headphone amps.Since they are located near Nuremberg,I think Jan will get a few new happy customers
My only regret is that this amp shows the shortcomings of my SE530s.And I am seriously considering sending them to UM for a remold with the addition of two drivers,one on the high and one on the low end.Maybe this will help!
Thats it for now,if you have questions,feel free to ask them!
