X dissenters
In my relatively short experience ITB,and it's possibly due to my previous experience racing and maintaining Motocross bikes long ago,but it's[ X2's reliability]is incredibly based on knowing your Hardware.
Just over 2 years ago I'd literally never ever touched a computer[except a bank ATM!]which I'm not proud of,I was just a struggling "luddite" but experienced electric guitar player,anyway I fairly impulsively bought an i7 dell xps L502x,though I was extremely lucky,as had I ordered 5-7 days earlier,I would have ended up with the previous model,the xps L501x,which according to a poor chap on gearslutz,couldn't run ANY DAW,due to horriffic DPC latency,and he was trying with the "just released" RME Babyface!
Anyway,I had some major hurdles,with X1[Tascam interfaces,95% user error],so I researched[very very easy,with the insightful posts of Jim Roseberry,and even more so,from Scott from ADK]and bought a parts picked,STORE ASSEMBLED win 7 64 Professional desktop,and guess what? Not one thing has EVER gone wrong,on That machine,with X1 ABCD and Expanded,and now X2! It's quite incredible.
I still prefer to use my laptop,[which throws tantrums,and quibles,but I still get my projects done],mainly cause the room the desktop is in,is either freezing in winter[now]or Oven like in Spring Summer Autumn[Oz is a land of extremes!]but really,I think it's because I just cannot stand my Rokit 5" G2 monitors,sure they go loud[I like to mix VERY quietly]have big bass,for such small drivers but mids,high mids,highs to an extent,are just complete fog,but that is another story!
The way I see it in these 2 and a bit years of ITB recording,is it's your computer,and its happiness,that IS paramount for Sonar,PT,or anything else to work,even semi perfectly,until then,a different daw,may even make things worse?,Oh and even though its 27 months with computers TOTAL,it's 30 years with electrical guitar...voice?,not too long.
Good Luck
