Just picked up a H K twin power 930 this amp really surprised me bass is tight and has a lot of punch compared to my pioneer sx 1250 and my yamaha cr3020 and the mid's are warm almost tube sounding and great high's i never would have thought this litle 45 watt amp i paid $35.00 for at good will would have out performed my pioneer and yamaha. ok the cr3020 is still a very nice amp better than the marantz, sansui and pioneer of the day but damn this litle H K 930 hangs right there with it. So i guss i will have a pioneer sx 1250 and sansui 9090 going on ebay soon. dose anyone else in this forum use a H K twin series if so what do you think of it ?
