From Denon amplifiers, PMA 2000R....PMA 2000IVR, and !!! PMA S10II,at their price and more are very ,very hard to
beats in construction and sound.They are very powerful in driving problematic speakers.
It is a great pity that Denon has not manufactured amplifiers of such quality for a long time.
With some Dynaudio (old speakers),with a good source,and with the right cable you can have a sound hard to beat with that money.
