Hi Rohin,

I don't have THD measuring equipment. AUD200U is not good(audiophile)for full band.Best for MID band and SUB woofer.
compare with class AB{ dB BASIC 400 BI-AMP} AUD200U is very good performer.

How many days will it require to complete your board?

Hi Sabir,

I think more than 21 days for completing PCB and over all it will take 45 days

Closest chip to U5, looks to me like:

Hi cresnet,

No it is not an6551.It's VCA (Voltage controlled amplifier)
