How do these compare to say a run-of-the-mil DENON micro-system < R8k ?
You can get some, IMO, well priced and pretty high powered Class D boards & an SMPS PSU to power it for a very reasonable price and that will sound better than your run of the mil AVR... Or so many have claimed.
I am in the process of getting some LJM L15D amp boards, these are based off the IRS2092 chip and many have said it sounds really good. One guy in particular had a mid-range Onkyo AVR and says these are far better than his Onkyo unit.
2x mono amp boards & a SMPS to power it will set you back around $100 with shipping.
You should be able to get 150W into 8 ohm per channel roughly.
If you'd like, when I have mine build in the next month or two hopefully, we can meet up and you can have a listen. Perhaps even bring it over to your place to hear on your speakers - if you are in JHB?
If you are keen, drop me a PM.
