Totem Forest Speakers.....

A square box is the worst scenario for acoustics. The Krell sounds average to bad with the stock power cord and run un-balanced. You shoul run it balanced with a musical CDP and a great PC and interconnect like MIT offers. If you want good advice from a veteran in the business call Joe Abrams at Equus Audio (Portal Audio). He will cut through the "well intentioned advice" you are getting and give you some solid options to pursue:O)

I would definitely change the amp; it is not a particularly "musical" component. Contrary to other posts, IMO it is much too analytical and clinical for your speakers.

I would also look at the cd player, speaker placement, and room treatments as well.

If totem's are anything like triangle's, 70 hrs. is not even long enough to sufficiently break them in.
It took my speakers 250-300 hrs. to even begin to break-in.
prior to that they sounded flat, constricted etc.
Consult the manufacturer to see what they say about how long it takes to break-in.
I don't know of any speakers on the market that are totally broken-in under 200hrs.
I think here patience is in order. If after 200 hrs. you are still having the problems you describe, then look at some of the suggestions that have been offered.

Change the amp-- Krell is a brand that appeals to only some audiophiles...they have a tendency to be quiet "dry" sounding. I think what you are describing is possibly a uninvolved sound and lack of warmth. Look at these brands..

Plinius
Naim
Sim audio
Classe
Mcintosh

All the above brands have more of a "laid back" sound than krell. Dont get me wrong some speakers love krells sound because the speaker itself is laid back, and when you add a more aggressive amp, you can get a neutral sound. Totems are somewhat neutral-bright speakers. So amps that are neutral sounding or warmish sounding go will with totems. Also look at replacing your source. Brightness and uninvolved sound is sometimes caused by jitter. The forests are a VERY reveling speaker for your Yamaha CD player. Look at getting a Tube CD player that will be much more musical and involving such as a Cary or Musical Fidelity.

Remember one thing...Forests (as well as the other totems) LOVE power. You will need a separate or a integrade that has 30+ amps to fully control the forests bass.

As far as room placement, I think it can affect the sound greatly, but with out proper electronics, room placement will only matter to a certain degree. Once you know you have the electronics correct, then you can experiment even more with placement. But I dont think right now is a matter of bad placement. Just make sure that you have the forests at lest 2 feet from the back wall if possible with no toe in.

I told you what would happen:O)
