Pit a 50W cheap amp against FE a Pass amp and you will hear remarkable differences.

Pit cheap 100W speakers against decent speakers, and with a good amp, you will also hear remarkable differences.

I don't want to criticise your speakers, yet, because we have no idea what they are.
I don't think it's necessary to disclose such private information in order to have a discussion about this topic. I gave you the relevant information about sensitivity, amp rating, room size etc

It's been said before - "The BEST amplifier that I ever heard was only 3.5W RMS per channel. It did cost over 3500 though."

But 3.5 watts isnt enough to go loud with average speakers? I used to have a 15 watt amp and it was easy to get it to distort quickly.

A good amp with good speakers will be LOUD at 5W and almost unbearably loud at 50W.

If your 50W amp cannot provide the volume that you require then something is WRONG.

Either the amp is rubbish or the speakers are rubbish.

In a normal listening room 50W is MORE than adequate.

Please refer to ANDREWT post #2

500W will give you double the volume and 5000W double the volume again. This is the nature of human hearing - the logarithmic scale.

At 50W we are talking about the average GOOD home Hi-Fi at FULL-TILT.

The Arcams and the Pass fraternity at maximum power.

I was talking about a World Class Class A Amp.

Please check the spec on the 15W amp, it was probably 15W PMPO which will be well below 15W RMS.

I run my Pass Aleph 4 at High Volume and the TRUE RMS figure is about 6W at GOOD volume. What it does have is ENORMOUS (100W) headroom.

Actually, we CAN do basic arithmetic with dB. 10dB + 20dB = 30dB. Seems simple enough to me

Measure the voltage at your speaker terminals. With my 90db speakers, I only use about 2 watts when playing at a very loud volume. I doubt that 50 watts is too little for you.
