I own the AVM2 and have not auditioned the AVM20. The AVM2 provides a good balance of sonic quality and AV performance for the money (I bought a pre-owned unit for < $1,500). I'd say look at the quality of the balance of your system to decide whether spending the additional cash is worth the added performance. If your system will discriminate and reveal this difference, then feel free to move up. You can also bypass the AVM2's DACs by using the analog inputs.
