I might actually be done. I find that this is the system sound I have been looking for. It can be played from very low volume levels to very high volume and gives me what I am looking for. The mid range defines the system and it is all there. The low end is present but not overwhelming and the system can be listened to for hours without being fatiguing. I have it tweeked with my room. My concentration has been on buying music. . Thats it for now. Stephen
