Assistance with Coincident set-up


I have Coincident Total Victory IV speakers with Frankenstein II 300b amps and a Supratek Cortese Preamp. The components sound very good but when I listen to classical music I would like to have a little more push when the music goes from a soft passage to something loud.
I don’t want to lose any low level detail , that the Frankenstein amp is known for, or as little as possible.
I have $4000-$5000 to spend on new or used.I can’t afford the Dragon II amps they are 10K, and that is out of the question but if I had the money that is what I would get.
My question is will a more powerful amp help or if I changed the preamp would that give the classical music a little more up front push? I want a remote control and phono with the preamp.The Coincident speakers and amps sound very good, My system never sounded so good , I hate to mess with it but if I can make the classical music a little more dynamic I’ll be all set .
I’ve only had two tube amps in the past one a 300b and the other a 45. Is there another tube other than the 300b someone can recommend ?
I’ll keep the Frankenstein until I can find and amp that has the low level detail of the Frank with more power.I may keep the Frankenstein forever it is that good !

Any suggestions are greatly appreciated, my listening room is 12 feet wide and 17 feet long with 7.5 feet ceilings.

Hi Abill,
I have heard the new Dragon MkII. It has tremendous dynamics with a purity that closes the gap between it and the Franks.
That being said, I will never replace the Franks. Should I wish to seek out my dynamics from my system, I would go the high quality pre amp route.
At this time, the Franks with the Pures gives me everything I need and more then I ever realized I wanted!
Listen preferences lean towards jazz,small scale classical and 60's to early eighties rock with an average of 85 spls (high 90's peak) measured from a seating position 7.2 ft from speakers with an spl meter app on my iPhone.

I think Abill realizes the true gem he has in the Frankenstein MKII amplifier. Jimmy I agree with your opinion of the Statement linestage and hope Abill gets an opprotunity to hear it with his Franks one day.
Thank You Jianming_pang for taking the time to post.Your info is very helpful.I'm not in any hurry to change anything.I like your suggestion to update to Coincidents new ShotGun Cables. Trying to save but it's almost impossible in this economy.I'm spending more time enjoying what I have and trying some diy anti vibration tweeks.The last two or three days I'm fine tuning the location of my speakers.Last night I thing I found the speaker sweet spot,it's amazing the change I got from moving my speakers an eight of an inch this way or that way.
I also ordered more vibrapods (#1 and #2's)and also fine tuned the weights with lighter vibrapods,making one change at a time.
For the last few months I changed my mind set to if it doesn't sound right it's not coincident products and it is paying off in spades !!
I am happy with my Coincident speakers, amps and cables.
My system imaging and dynamics are much improved since tweaking system and getting new preamp tubes.

I'll report back when I get the shotgun cables.

Thank you everyone I appreciate the comments.
Montejay , forgot to mention, thank you for the post on the Dragon II amps.
I don't think I can come up with the money for the Dragons but if I do come into some money I will get them.
Who knows I may win the lottery.
