After a few weeks of playing with RS1  I still think it sounds a little dark and it misses the spark lower grados have. SR60 seems much brighter, a little louder too but also extremely fatiguing. I could listen to RS1 for hours while half of hour with SR60 gives me headaches.
All in all a great sound, very detailed and voice reproduction is out of this world. While Sr60/ 80 can sometimes sound congested, RS1 never does.  But I still feel something is not right. I took my RS1 to a specialist hi-fi retailer, he had a play with them and he said HP are ok. After listening straight from an iPod.
 
I have done some research and there are other people out there reporting dark and fat sound with RS1i compared with RS1. I have the thick cable butonless RS1 which is in fact RS1i me reckons.
 
I didnt have the time to buy an amp yet, I will most probably go for Little Dot 1+ and MK1+. Would there be a possibility to brighten the sound a little by replacing the stock tubes? I would love to have same bass and mids, only with a little more sparkle.
 
 
PS: any RS1 veterans in London that would like to have a go with mine and give their opinion? Thanks for your help so far

I do think an amp will make a difference that you will appreciate, and if you can find one in the for sale section, check out the Millett Hybrid Minimax (or the MOSFET Max). I thought they did a really good job at making the my Grado's sing

Yes, by all means buy an amp for them if they're not sounding good to you as they are and welcome to the point of diminishing returns.
