PQ in Solo2 is excellent, better that in DM800 I used before. Tuner sensitivity is better too. I have tested various images on Solo2 ( latest BH, VTI, VIX, PBNIGMA) in multi-boot environment. All images work well and are stable enough. PQ of HD channel transmitted via LAN is excellent too due to 1GB LAN I used with Solo2. I must say that PQ depends on image configuration ( particularly, I recommend you not use various PQ software improvements) and the comparison is correct when similar configs are used.
