Help: WPC for my speakers

I will try to keep this short. New to the hobby and already have upgraded speakers. I now have system audio 10s. They are 88 db and have 8-4 impedance. Min power 50 watts Max 135 watts.

Currently powered by 50 watt exposure super XV. I got the bigger sound, much better clarity and much better tone accuracy with the upgrade. What I lost was the pin point accuracy/ tight bass that my smaller system audios had. I believe this is do to the lack of power I have using the exposure.

Do you all think more power will solve these problems? Second I am looking at a DK design vs1 mkll by LSA group used. This amp would be 160 wpc at 8 ohms and 320 wpc 4 ohm. Will I have to be very carefull about over powering these speaker or should I be ok with this power

Imaging and pinpoint accuracy are more influenced by speaker positioning and room setup/interaction. You need to spend some serious time in experimenting with the placement of your speakers and with mitigating early reflections, etc...

everthing is pretty modest and has not changed except speakers. Exposure Super XV -used- marantz 5004 cdp- project debut II record player- 0ld sold core exposure wire.

I moved up in the system audio line. First entry level now a little higher. The SA 505 had better base and more pin point image. This is why I
think I have a power issue.

would he LFD amp be too much power?

I don't know your speaker or amp. Based on the fact it's an 88db, 4ohm speaker, I would guess you are underpowered.

I don't know your speakers either. Regarding the bass issue, more power can almost always help. Given that I don't know your speakers, I really don't know what to make of the imaging. Are you sure they are broken in?

I'll try to address the last part of your question.

"Will I have to be very careful about over powering these speaker or should I be ok with this power."

A lot of people have a misunderstanding that amplifiers send power to the speakers when, in fact, the speakers draw power from the amplifier. When an amplifier has the potential of supplying more power than the speakers can handle there is potential that you could turn the volume up loud enough for the speaker to draw more power than it can handle, but it isn't likely unless you're looking to replicate rock concert volumes. More than once I've heard Focal 806v speaker hooked to Krell monoblocks capable of supplying 300 or 400 wpc at 8 ohms and even when they were turned up louder than I would ever choose to listen there were no issues. It is my understanding that more speakers are damaged from an amplifier not having enough power than from being overpowered.

I don't think that having more power will necessarily improve your perceived bass response. But having said that, any amplifier that doubles the power from 8 ohms to 4 ohms should eliminate any concerns about the amplifier being the issue. It appears that you're talking complete apples and oranges with the two amplifiers.
