The price of your equipment bears little relationship to the sound it may produce. While it may be a "general principal" that the more the equipment cost the better it will sound... it... does not mean there are no exceptions - there are many!
I bought a $700 Class D. Audio amp a few years ago (SDS-470C Class D Audio Power Amplifier - 300 watts / channel at 8 ohms), and it drives my $1000 Maggie LRS+ speakers to "audio Nirvana."
That’s about as "cheap" as you can get for great sound! Though, I am using a Bryston BDP & BDA as the source.
