IDA-8 has achieved the perfect balance for an entry level audiophile integrated at unbeatable price for the sound quality.
To be honest, we don't know how to make it sound better or more powerful without increasing the price by more than 50%.
It is kind of like the Dad's personal music system whereas Omnia A300 is for the whole family.
Cultural and geographical preferences are also quite different. So we do have some people that prefer the A300 sound over IDA-8.
What the IDA-8 lacks is a very good but low cost streaming transport (Stream 9 Mini).
But we have to release the incredible Stream 9 transport first.

If budget allows, go for the Stream 9 (less than $1K, exact price available end of Feb), you will not regret it. For the same music, ie same 16-bit/44.1kHz music from CDT-10 versus same file streamed from network NAS, the performance of Stream 9 rival that of CDT-10.
