Re; Dynamics, Class D vs tubes…


Class D amplification vs tube amplification, which is likely to be more dynamic at lower volume playback?   Assuming speakers that are more difficult to drive than average.  Let’s say, 4 ohms dipping to 3.2 ohms and running about 85 db efficient.

@daytrader , @billstevenson has this right. Whatever dynamic contrast that exists in the system should come from the signal and not the amps. Some amps can 'sound' more dynamic than others but if you measure them you'll see no difference. That is because distortion can cause the ear to be fooled into the perception of dynamics.

A good class D amp can sound right, like an excellent tube amp, at low volume no worries.

Thanks Ralph. 👍

 

So amp typology for the most part isn’t going to matter much?  Tubes vs solid state is closer than ever but still obviously not identical delivering music.  I guess I’m just looking for a better full range match for my current speaker choice.  While still keeping the equipment with the least amount of change.  I tried the KT150s for a little more bottom end , approved by Mike Sanders, but didn’t like the frequency response.   Might just have to stop here and let sleeping dogs lie.  

@daytrader , your last sentence is a worthwhile venture and costs nothing for now... ;)  You've indicated rather particular desires, worth the time to spend to satisfy.....

Unless there exists a specific event in mind you've the desire to indulge...

@hilde45 's use of 'lubricious' in regard to class choice imho has never struck me as important under the typical use of the term. 🤷‍♂️

Personal experience the musical source tends to be silenced while a more primitive and generally more satisfying duet occurs....hopefully...😏

YRWV....sorry. *G*

The Chicago show is coming up....perhaps time for an audio exposition expedition?

Put together a dongle within it the sort of detail you'd want to have.

If a vendor won't play it between demos, then you'd rather not have their stuff. ;P *L*

@daytrader It better not. The dynamic contrast in any system should arise from the signal and nothing else. Its the system's job to convey this and do so without compression. Lower efficiency speakers do have a phenomena known as 'thermal compression' which is not an amplifier thing. This is one reason higher efficiency speakers are often cited for superior dynamic punch.
