Why my system has detail but no body & warm vocal?

Your system has bright spks, electronics and spk.wire/interconnects. First off I would change spk. wire/intercommects. Add after-market power cord to your Ra-972 if possible. Electrical outlet may be old and needs to be replaced. If these changes do not bring about desired effects either change amp or speakers. If you decide to go the spk. direction, Spendor would be a good choice.

Change to a speaker with warm midrange

Before you start changing equipment do you have a friendly local dealer who can lend you some different cables to try in your system? Kimber is good but may not be what your system wants. Try a different ic first on the cd...you're looking for that elusive synergy. I've used van den huls 1st and 2nd carbon ic's on rotel cd players before, with success. The carbons offer some warmth with a slightly relaxed attack. They could be purchased second hand. I've also used the carbons on a rotel amp...just a thought..good luck.

The Arcam CD 23 or 23 T reproduces the tone of musical instruments and voice in a delightful way and, at least in my system, gives a palpable presence to Ella, Sarah and company. I wouldn't expect any miracles from magic cables on either end of your components. Your room acoustics (including placement of speakers relative to walls and the seating area) should be addressed also prior to buying any new equipment. BTW the CD 23 can be gotten used on 'Agon for around $1000-$1300, an excellent price/performance ratio.

My friend and I both tried my Kimber 8TC speaker wire on our systems and we both like it a lot but think it is lacking bass and would be more suited to a warm system. I imagine the 4TC would be similar and would start there myself.

BTW the Hero has gotten some good reviews in the magazines and by fellow listeners, I would be hesitant to get rid of them without experimenting first.
