I have not heard Creek Destiny amplifier, so I cannot comment. However, it has good reviews. I would advice you to never buy audio equipment based only on reviews.
I also listen to Jazz, Classical, and Classic Rock. Based on my taste, I would choose Cambridge Audio 840A v2.
Also check Simaudio i5.3 integrated amplifier. I recently heard the i5.3 and I was amazed by its performance. It outperformed my VTL/Bryston combination. I am thinking of buying the i5.3 amplifier, it is an amplifier I can live with for a long time and also simplifies my setup. According to me, Simaudio i5.3 outperforms Bryston B-100 SST, Plinius 9200, Krell KAV 400i, Naim SuperNait, Linn Majik i and Musical Fidelity A5.
