 How about other reasons that bring down quality?
 1. Your Android audio framework is not supported, this not uncommon on HTC devices.
 2. Audio amplitude clipped(#2), this is a obvious reason which produce strange sound, try to turn your volume down!
-3. If you are using convolver, did you try to use smaller normalise(#3) value, which control overall impulse response amplitude level.

 4. Tube modelling require a high performance CPU to output best quality, so I turn down algorithm precision. **This may produce low amplitude noise.
 
 #1: Floating point rounding issue is not taken into account.
 
 #2: JamesDSP use limiter to reduce clipping harshness.
 
-#3: This option will be changed to simple amplitude control.
