I would want to avoid the used AVR route.
How good will a combination of Pioneer VSX-330 + Taga harmony TAV-506 be? Will this be better than the YHT 1840 setup?
This option is going to increase my budget considerable and delay the purchase.
I want to build a decent HT setup. The definition of 'decent' is not yet aware to me and this will happen only if I'm able to experience the system for over a period of time. I have been reading from past couple of weeks before starting this thread, and after all the reading I have done, for a user like me who is building his first HT setup, I would like to start with the basic and plug-in/add the missing pieces in the future.
I consider YHT 1840 would be ideal me for now.
Why the YHT 1840? Well, its a HTiB, so I can basically start using it right out of the box. I would get a fair idea of what the HTiB is providing over a period of time (the quality of sound, the amount bass, etc). Since this would be a complete setup I wouldn't be impulsive on making upgrade decisions. I may or may not add/upgrade components based on my usage.
I'm still not sure if this is the right path to proceed on but I absolutely do not want to regret investing bigger money on things which I'm yet to discover.
I think Pioneer VSX-330 + Taga harmony TAV-506 be is considerably good than YHT 1840 with dedicated subwoofer out and usb port for playing music directly from avr, but i am not sure about the sound quality that you expected from these combo than yht 1840 since the pioneer model and taga speakers you choose are also a entry level ...
