Krell amplifier with Hales speakers?


I was wondering if anyone could shed some light on they synergy of my system concerning the amplification. My current system consists of a Well Tempered turntable, Acoustech ph-1p phono stage, and Krell KAV 250cd front ends, these feeding a Krell KAV 300i integrated amplifier. I have all Audioquest ruby interconnects, and Audioquest type 6 speaker cables. My speakers are Hales Revelation Threes. I am wanting to upgrade my preamp/amplifier, should I go with seperates? I am looking at a Krell krc 3 preamp, and either Krell monoblocks (kma 100) or Ksa 150 amplifier.

I guess that I wasn't aware that the Hales speakers are so hard to drive. THey do tend to sound on the bright side, but they are pretty good in the lower region. I have about 4000 dollars total for preamp and amplifier in my budget. I don't think that I will be able to find any fpb amplifiers at a price to leave enough for a good preamp.
NRCHY, I have considered going to a cable from transparent audio, after auditioning some in my system I felt that it had a much smoother sound without the grain in the highs.

I tried different speaker placement tonight, according to the "golden rule theory" on the Cardas website. My room is 16'5" WIDE, x 22' long. With the speakers on the short wall, approx. 88" from the wall, and 53" from the side walls, the sound stage was dramatically better. I am beginning to hear what the Hales can really do, and I have owned them for 3 years!

After about an hour and a half of listening, I moved them back to the original position, 48" out and 36" from sidewalls, and I was floored at how BAD they sounded compared to the other postioning. Less soundstage, shrill treble, and muddy bass.

I still think that more power would give the speakers more "punch" and "immediacy", since they sounded a little flat that far out in the room.
OLALA, No I don't have the speaker manual. If anyone has one and would be interested in copying it, I would like to know.
Hello, here is an update to my system. I came across a Krell ksa 250 and what an improvement in my sound! The bass has punch and rhythm, hard to explain but an overall sense of the amp being in command of the speakers! This is what I have been lacking in the sound. I am currently using the pre-outs on the kav-300i to drive the ksa 250. I still need a preamp, and have now been reading favorable reviews of the krell kbl. any thoughts on this?
Thanks for the info. What preamp are you currently using? In your opinion, what tradeoff am I making right now running through the kav 300i as a preamp, using the pre-outs? This is an integrated amp btw. I will try to install a dedicated 20a line as you say. I did this at the last house I owned and the improvement was noticeable even with the kav300i.
I think that the soundstage is a little too forward for my taste. I guess that I am blaming the preamp section of the kav300i. I read that this is a class "a" preamp section, but wonder what tradeoffs were made to fit into a 2500 dollar integrated? I have hear some tube preamps and have been impressed, but think that keeping everything Krell will result in a synergy that I want.

Today, I borrowed some Transparent Music Link cables to try out. One is the Standard cable, and the other is the Plus cable. I want to see if they take some of the grain out of the system that I hear. From what I have gathered, the components that I have should be relatively high resoloution and without grain. I think that the Audioquest Ruby cables may be contributing to this.

Will let you know how this turns out.

I am also wondering about the likelihood of the KSA 250 needing to be serviced. When switched on, there is an audible "clunk", and also when switching off. Does this mean that Capacitors need to be upgraded?

Thanks for all of the feedback.
