PrimaLuna EVO 400 v Cary SLI-100

If you could hear a Raven Audio Osprey with best tubes setup

you would be amazed at what you hear..

Good Luck in your Tube Amp Search..

The bottom line is we can all tell you our stories and what we hear...    But your hearing and listening room may not even produce what you want to hear from our equipment if in your room...  The bottom line is try and go and listen to a few and see if you can bring it home and try it.. Not Until you hear in your own space will you know if tubes are for you...And listen to what others are saying about tubes and try and get close to best tubes when you listen to  first time..Try and find others that knows these units you are thinking about and chat with them a while on their tube selection ....I was lucky enough to start with Raven Audio and owner Dave knew his machines so well and I explained that I had tinnitus and he would send me tubes to see what matched my hearing and give me best quality sound..I had Osprey for 5 years and Dave over those years shared with me some very nice tubes to keep me happy ..Like anything you purchase over time you will get tired of it and want a change and nothing big but little detail will spark your hearing again ..Just a change of tubes weather power tubes or pre amp ...just 2 pre amp and what a change can make...But if you get  hooked with tube amp sound chances are you enjoy many years of sound you never heard from a solid state...But remember not all songs play through tubes as they do through solid state .. I find tubes break down a song and segregate sound to speakers and solid state keeps it more tighter in sound..This is what I hear from tubes vs solid state..  I also find that some songs I luv and using KT88 tubes they are to airy and need say a 6550 power tubes ..Nothing is perfect ... + / _ no matter what you listen to..
