Turntable-Amplifier-Speaker configuration question.


Sorry if this is a silly question, but I am getting back into home audio for the first time in many, many years. I recently got back into vinyl and purchased a Technics SL-1500C with a pair of KEF LSXII speakers. It sounds great, but apparently the amount of volume I can get to the speakers is limited because of the Phono to AUX routing I need to use into the speakers. I tried using a Denon amplifier to see if I could get a louder signal, but that didn't help. I am wondering if someone could suggest a setup for my turntable that would get me the fullest possible range of volume. I am open to starting with replacing the speakers and purchasing a new amplifier/reciever.

I am not a vinyl person in anyway. I say this asking, what streaming service are you using for your KEF speakers? If the answer is not QOBUZ, I suggest you try that and then compare that sound quality against what you hear with your vinyl. Not trying to convert, just giving an option before spending some money on a new amp and speaker system for vinyl playback. 
Also, are you using a subwoofer?

@nickb64  -  You stated "Phono to AUX routing".  Can you clarify if that means you are going directly from the turntable to the speakers Aux input; or if that means Phono preamp to speaker Aux input.  If you mean the former than the  issue would be not having a phono preaamp and one that appropriately matches the cartridge you are using, whatever that may be as you didn’t mention it

For us to understand the electrical requirements of your system, we need more information like brand+models:

  1. What cartridge are you using?  Cartridges differ in their electrical output 
  2. What phono stage (preamp) are you using?  Phono stages can differ in their electrical output amount of amplification from the cartridge output to line level for a preamp.
  3. Are you using a preamplifier before your amplifier? If so, what’s the brand and model?
  4. What is your amplifier?
