Hi!Thank you Partha for your comments and heads up on the cooling as others have also pointed out, which I shall be implementing as the avr is used in my lounge setup which is on almost constantly from after breakfast till 10pm at night. It is not my main setup and will only be used at moderate volume of up to around -20db and occasionally -15db region.
I have a Marantz 7010 7.2.4 in my cinema room with PA and mainly XTZ cinema series which I use for more serious listening on a PJ based system when I can go up to much louder volumes of -10db to near ref when necessary.
The speakers I will be using with the 4500 will for the time being mainly be a bit of a mixture of Atlantic technology LCR & surrounds with some MK K4 to use as the front height speakers although perhaps over the next few months I may change that around a bit.
Thanks for your reply
I am using the 4500 in my bedroom with 2 channels only and using an age old pair of floor standers Yamaha NS-200 -superb sweet sound despite being more than a decade old.
The 7013 is driving the new B&W 603's and HTM6 as center with old yamaha bookshelves as front heights and surrounds.
Sometimes later I may change the old Yamaha's with Fyne Audio F501 or Dali Oberon or Focul Chora -depending on audition experience.
