One of the best advice I read from a book (the Complete Guide to High End Audio) is to match the value of your electronics (receiver) to your speakers or
higher. So in application, if you bought a P40,000 ($800 like the
Wharfe 9.6) speaker, match it with a P40,000 receiver or higher for best results.
Just so happens we are lucky that wharfes are cheap here, but consider Wharfe's
international price NOT our local price. Huwag dayain!
So if the Wharfe 8.4 is $600 internationally, try to get an equal value receiver
or higher for best results. If you cant, there is no harm in holding back for awhile and make more savings to get what you want (or go for pre owned). Its better to get a good one than a mediocre AVR & then upgrade later, wasting time & money.
The truth may hurt (the pocket) at first, but in the end you will appreciate this advice (if you follow it). Your HT system will give you many years of satisfaction, instead of dissatisfaction or selling it in the B/S section cuz its "bitin".
