I am putting a TV out in my shop along with some old Infiniti bookshelves. In my house am currently using a Denon x1700H for my Martin Logan motion foundation B2 shelves and center with a RSL 12s sub. I would like to move my 1700 out to the shop and get a bigger avr (watt wise) for my house. There are quite a few used 4500's out there, but am I just wasting money?
Thanks
It may or may not be a waste of money. First thing to do is to find out how much voltage and current you need based on 4 ohms.
The 4500 offers none to very subtle difference in sound quality if the 1700 is powerful enough for you already.
The best website for online audio amp/speakers calculators seem to be Benchmark's but you may find it hard to navigate as their offering is quite comprehensive, covering many scenarios:
Benchmark System Calculator - Benchmark Media Systems
If you don't know how to use the calculators then let us know the following and we can do it:
1) Your seating distance.
2) Highest sound pressure level (SPL) you would like to listen to without hearing distortions.
3) Your speaker's sensitivity, impedance, and recommended amp power, but you told us they are MLM B2 so we can find that info from ML website. They are 5 ohms, recommended 15-100 W.
