Impedance mismatches between pre and amp do this?

I think thats whats happening to my Arcam A65plus (used as a pre) and B&K st-140. Will this harm or damage any of the components in any way?

My system sounds good in the mids but the highs are grainy and sound forced while the bass is completely missing. The upper bass is tight and the detail is still there but there are huge gaps in the sound. Im waiting on a used PS Audio 4.5 preamp which should arrive Friday or Saturday along with some Synergistic Research Alpha Sterling X interconnects. Hopefully all this with my B&K ST-140 amp, Music Hall cdp and JM Labs speakers will bring me the satisfying sound Ive been searching for. Any help or opinions on coming system or causes of crap sound?

Im not sure if it is but someone else on another board said it was. Do those numbers coincide with a passives ouput? Im taking it with a grain of salt but who knows? Anyway Im anxiously awaiting my PS Audio 4.5 preamp. Ill let you guys know how everything turns out when I hook it up Saturday (knock on wood). Thanks for the help!

I received my PS Audio 4.5 pre yesterday and hooked it up to my B&K ST-140. All connections were made with Synergistic Alpha X ics and speaker cable. The sound in Straightwirde mode is very clean and smooth with good presence. The bass is tight and full and the highs although slightly rolled off are very clean. Soundstage width isnt incredible but acceptable, while depth is better. Instruments are all equally represented with the only emphasis being on vocals. They are firmly centered and clear, giving the music a more "you are there" feeling.

This brings up an interesting dillemma for me. Is music supposed to sound like a live performance or a good studio recording. With my Arcam the music sounded like a great recording (with the exception of harsh highs, prompting the switch). With my new setup the music sounds more natural. Both are enjoyable but different.

I dont use the active high level mode because the bass sounds gritty and loose. Thank God everything seems to have worked out with this new preamp (knock on wood). Now to buy more music. Thanks for all the help guys.

Awesome Bundee! Glad to hear it worked out.

Whether your music should sound live or studio recorded is totally up to you. Many people try to build a system that reveals the "true" nature of the performance. I on the other hand like my music flavored in a distinct way, so I've picked gear that puts me front row, center whether it's a concert hall or a small, smokey nightclub.

In my book there is no proper way except the one that pleases you.

Enjoy!

Well ive purchased the alpha sterling also. These are very fast cables. The sound horrable on my tube amped system. Good highs colored mids and no bass. These are great cables best for overly warm systems. im selling these suckers. My system must be pretty screwed up because these ate interconnects of the year. God
