Considering a POSSIBLE replacement for speakers. Opinions?

Hi, and thank everyone for their responses so far. I should have set aside time to make a proper post rather than ask a simple question...because we all know there are no simple questions when it comes to audiophile questions, right?

First, artemus_5 is right. I had thought I'd listed my current system in my profile but apparently not or it got lost. Get ready, it's a mismatch of equipment that still sounds beautiful.

Source: OPPO BDP-105 ( not the audiophile version )

Preamp: 1993 B&K Sonata Pro-10 MC ( totally refurbished 4 years ago ) 

Amplifier: a matching 1993 B&K Sonata ST-202+  ( the rare kind, totally refurbished this year )

Speakers: 2008 Monitor Audio Silver RS8

This last part eliminates a lot of suggestions so forgive me for not mentioning them.

Subwoofer: 2 Sunfire SDS-12 subwoofers. Two of them.

I listen mostly to prog rock from the UK and US along with Zeppelin...70's stuff, and moving forward all types of EDM from Marshall Jefferson to Orbital to Underworld, Daft Punk, etc. More rarely I do listen to large classical orchestra pieces like Beethoven's 9th.

Clearly, I can have a block party with this system if I need. It's been quite some time since I changed or added anything but...you know how it is. My speakers are 12 years old now and that itch is back. But maybe it's just an itch I don't really need to scratch. The B&K stuff cannot be replaced by anything reasonably priced that equal their abilities so about all I can do is upgrade the speakers. Call my budget for that around $2,500-$3,000.

So, can I get a better sound by upgrading the speakers in that price range? Thanks Everyone!

Again, apologies for not listing all the components. A Cardinal Sin, I know.

Also, I am located in the Dallas-Ft Worth area if that helps at all.

If you like the Monitor Audio sound, it’s a safe bet to go with a newer/better MA speakers. Your budget can accommodate MA Silver line, but if you’re willing to buy used you can afford the MA Gold300. Above the MA Gold line is the Platinum (PL). Also, within each line the larger the model number (100,200,300) the larger the woofers and price.

Great pair of monitor audio pl100 mk ii for sale on us audio. 2500.00$.

may be your best option if you are satisfied with the bass drivers performance.

LSA garnered many very positive reviews before selling their business/inventory IIRC to Underwood Hifi. Seems like Underwood is keeping the LSA prices low to move inventory. For the price/performance, this is a sonic bargain. This seems like relatively safe bet.

Other speaker choices would be subjectively very risky without demo first.

I would avoid flat paneled speakers like Magnepan unless you heard them first. These speakers are very fast and great sounding, but the vibrating panels don’t push enough air to do bass well unlike piston driver speakers. Adding a subwoofer to augment the bass can be problematic as the vibrating panel is significantly faster than the piston motion subwoofer - there is a mismatch in timing. Some folks are satisfied with the added subwoofer sound, other folks not so much as they can hear the timing mismatch.
FYI- Magnepan may be creating a dual piston type subwoofer to match their paneled speakers timing - Google “Magnepan for Condos”

I posted a response and recommended he contact Jim Salk at Salk Audio.  However, my response was removed.  Are we not allowed to recommend manufactures who sell direct?  They make incredible speakers.  I was not aware they remove a response if you mention a manufacturer who sells direct?

@clearthinkier why you say not to buy the Moabs?
