Newbie needs help on Audio Research and DynAudio Quality

Hello all,

I am a newbie to high end home audio and need help from all of you audiophiles out there. I was actually into high end car audio back to when I was younger so I kinda understand what sound quality level can be considered at audiophile standard. I bought this set up (2 mono amps Audio Research Classic 120, Audio Research LS22 preamp, Dynaudio Contour 1.8 mkII, Rega Planet CD player) 4 years ago and did not have time and room to put them up to enjoy until recently. After setting them up last week, I was very disappointed at the performance. The sound was harsh and I would get tired after listening to 2-3 songs. I remember when I picked up the speakers, the previous owner played a couple of songs using his turntable and it was warm, clear and enjoyable (I could not remember what equipment he had back then). I have another set of solid state stuff to play around which includes Luxman M-12 amplifier, Sansui CA-2000 preamp, JBL 4311B, and same CD player Rega Planet. The sound quality is much better compared to ARC set. I expect that the ARC set at least has to be at entry level of audiophile but what I got out from it is disappointing. I need help from you experts to point out what is wrong or what I should expect from Audio Research.

Best Regards,

Dan
