Amplfiers that Sound like Pass 30.8 that are not so heavy

consider the class A Sugden integrated.

[please excuse my poor English]

Given the easy impedance (min. 6 Ohms, see graph) of your QLN Prestige 3 speakers, I would give the new and terrific NuPrime AMG-STA ($1695) a try, seriously. Compact and lightweight (8.8 lbs).

Input stages in class A. Output stages in class D.

Initially, I did not want class D amplifiers, not even to jam a door. I nevertheless had the opportunity to listen to the at home, and bought them in 30min. (with their AMG-PRA preamp, amazing too). This was for a 2nd system. But they are amazing.

Very nice-sounding, with a lot of transparency, image precision, and timbres (I listen to classical!). I was very, very surprised. Now, I think not all class D amplifiers sound that good. Moreover, you have to say "class D" with hyphens, as then did not pick up off-the-shelf class D modules (Hypex, etc). They wanted their amp to sound much better. They build their own circuit with very high switching frequency to reach the most "analog" possible sound.

2w130w. Switchable in mono mode (=> 2xAMG-STA gives you a pair of monoblocks for only $3390. It is this combination that amazed Christiaan Punter, excellent Dutch reviewer (see Hifi-advice review, hereafter).

I really appreciate their weight when I have to move them around. They sound much, much better than my 80w, 40lbs Marantz PM-16 in that 2nd system. I have not yet compared them though to my YBA Classic + Aries Cerat Incito preamp sitting in my main system (in another town).

QL Prestige 3 - IMPEDANCE

You could put it on a dolly if you’re moving it around frequently 

I agree with the folks saying that the Pass amp is special and perhaps you should just get help moving it, so you don't have to change it out.

That said, if you must change, I recommend that you consider the Son of Ampzilla II by Spread Spectrum Technologies (SST). 

• It only weighs 42 pounds and puts out 220 watts per channel.
• The sound is very Pass-like and exudes the best of aspects of a Class A amp - including running very warm.
• It delivers beautifully on every measure of sound you may have for an amp from bass to imaging to detail without harshness.

I admit that I bought this amp 6 months ago after a careful search and it will be my last amp.

Happy listening however you choose to go! 

I agree fully with the above post. I still own the original GAS Son of Ampzilla. Designed by James Bongiorno, a brilliant and under-recognised designer. When I got the amp I chose it in preference to Pass' Threshold!
