HI
@Pedro65
I would like to offer you some suggestions before you decide on changing your speakers and hope you don't mind. I have taken a look at the specifications of your Spendors and they have a respectable 87dB sensitivity. Recommended amplifiers are from 15 to 200 watts. Therefore, your Exposure amplifier at 100 watts per channel should be able to drive these easily and with aplomb. This leads me to believe your system may not be setup to sound at its best and probably doesn't
"sing" the way that it should.
I don't mean to tell another Audiophile how to suck eggs but if you're not careful, you might make some costly mistakes whenever you decide to upgrade. Wharfedale and Elac speakers are okay but they are not in the same class as your Spendors! When a HI-FI system is set up correctly it should Sing. Some Audiophiles call it "Synergy or Audio Nirvana. When the Audio system "sings" you'll look at your speakers and they will completely disappear and all you will hear is the music, which will be presented to you in three dimensions: Width, Height and depth. On a good HI-FI system (that's set up correctly) you should be able to pick-out where the musicians are placed in the room and there should be a clear demarcation between the instruments. Close your eyes and you will get the feeling that you have been transported to another realm. The hairs on the back of your neck will feel raised and you'll feel goose bumps along your arms and legs. The better the HI-FI system the more pronounced these sensations will be. Please don't think that I'm kidding because I am not, I am quite serious.
All the above is achievable and a lot more, but your system has to be set up correctly along with other important factors, which I will explain below. This will determine how much of this effect will be presented to you.
The first thing is to make sure your Audio equipment is placed on dedicated good quality "equipment rack". This will help to keep vibrations from the floor, caused by the speakers reaching your Amplifier , Turntable and colouring the sound. I cannot stress the importance of isolating your audio equipment enough. When done correctly the rewards will be huge. If you are able to place your Turntable on a dedicated " Wall shelf" made for this purpose that will better.
Interconnect cables and speaker cables can make or break a system. Please audition these in your system and buy the best that you can afford. I use cables make by the "Chord Company" here in the UK. If your HI-FI equipment has a detachable Mains cord, then I advise upgrading these to Good quality HI-FI screened cable. This will help screen mains interference. In addition to this, mains conditioners are a Must as they will supply clean electricity to your system and you'll soon realise the benefits. I also use Nordost QX4 and Qx2 mains purifiers.They will work with any existing mains conditioner that you have. Please do not underestimate these, once you hook them up to your system, you'll realise what you've been missing!

Room acoustics can make a big difference to the sound of your HI-FI . Plenty of information about this online. I have two audio systems with one room acoustically treated. If you ever decide to upgrade your Exposure amplifier, then I advise you to consider auditioning Valve/Tube amplifier. You can start off with an amplifier using EL34 tubes or KT88. These amplifiers will sound better than most solid state amps. The sound will be warmer and more musical. Many Audiophiles (including myself) consider an amplifier using 300B power tubes/valves to be the best. These tubes run hot and are pure class A. The sound is smooth warm very musical without a hint of harshness in the mid-range and treble frequencies. Once you hear the 300b amplifer you will never want to go back to a solid state amplifier.
I have two 300b amplifers. One runs in Push-Pull mode the other is Parallel Single-Ended. Both are 20 watts per channel and can drive my ProAc D28 speakers easily, which can handle amps from 10 to 200 watts. My ProAc Tablettes, Reference 8 Signatures are 10 to 100watts. Both amps can drive the little Tablettes without a problem and with very good sound stage. Size: 10inch High x 6inch wide x 9inch depth. The speakers are placed on Partington Broadside speaker stands, partly filled with lead-shot.
Both systems have synergy and create a wide open sound stage having three dimensions. I can easily pick where the musicians are placed and there's a clear demarcation between instruments.
Please remember your tinnitus and loud sounds. Try carrying out some of my suggestions along with tweaks of your own, and you'll probably find there is no need for high volume levels, especially with classical. This way the chance of getting a spike or noise trauma is greatly reduced.
Best of luck and I wish you well.
