Any advise to improve my system

Do we have any room treatment? Power treatment? Isolation treatments? As far as the equipment - nice choices. More always costs more; There is plenty of room for improvement/such as zillion $$ amps;speakers etc. No; Your not there yet. If these were my pieces,I'd have my eye on even better speakers. Remember we are all addicts; the journey is the fun part. It's easy to become complaisant/or bored; spending more money is the temporary fix. enjoy!!

It sounds like you have a problem with setup. Your equipment is more than capable of providing the detailed full range sound you seek. Play around with speaker placement. Also take a good look at how your components are sited (equipment stands, speakers spiked, isolation devices). One note of caution, above a certain level of equipment and setup, the recording can become the limiting factor. It's possible that you music simply doesn't have the kick you desire.

Actually they are nice speakers, so try moving them around and look at the room itself. If that dosnt help, its time to start thinking speaker upgrade. I am afraid the rest of your system has risen to a higher level. Try the Gold i and others. With your setup you shouldnt have problems with detail or bass extension. Good luck.

I agree, the speakers are the weakest part of your system. I had a Plinius SA 100 with my Meadowlark Heron I's. Detail and bass were great.

I have to agree with the folks that suggest new speakers. Remember that the speaker is the only transducer in your system, and is therefore the most subject to problems of distortion, non-linearity, etc. Further, your speakers do not have the full-range frequency response of some models, which is probably why you think you don't get enough "kick". You have a lot of choices in full-range speakers, limited mainly by how much you are willing to spend. Your Plinius amp certainly has the "balls" to drive just about any full-range speaker you buy. You will probably get quite a few suggestions about which speakers to audition, but I'd certainly listen to one of my personal favorites, the Vandersteen 3A or 3A Signature, which can be purchased used for about $1800 and $2500, respectively.
