Thank you guys for so many replies. I have no patience as IanL and most of you so I switched them right when I stepped into my apartment yesterday. I was listening to Radiohead - OK Computer from CD with my jaw on the floor (CD player is California Music Labs ICON MK2 borrowed from my co-worker who actually infected me with the tubes sound and I honestly appreciate this). So, when I was listening to Coldplay - A Rushs of Blood to The Head from Fiio X5 MK2 DAC and I found it way to bright without deep and layered basses. It could be related to 3.5 - RCA cable I use and it's $5 cable I had in my closet (didn't have a chance and money yet to move to decent cables). I'm also waiting for my Lounge MCR MK3 phono preamp to finally listen the same albums on vinyl. So, could you please recommend if I should replace cables first and then go with another tubes. It is not going be so fast but I just want to create a plan and follow it. I'm so glad guys I'm with you now and enjoying sound as newer heard before. Dreams come true. Thanks.
