New Joseph Audio Pulsar Graphene 2

From my correspondence  he said the sensitivity  was slightly higher but the subjective  impression  is greater than the measured  difference.  They had a fuller, richer more detailed sound. 

Not sure what is meant by the subjective impression other than if a speaker has a more detailed sound you will hear the music better which gives the impression the speaker is louder? I know it wasn't  the most cost effective  way of going about it but I bought used perspectives and after some back and forth with JA I  went ahead and sent them for the upgrade. When I bought them I wasn't  aware they had come out with the new version. Still saving a few thousand though. 

djones51,

Thanks for the info.

I think a speaker can sound "subjectively" more sensitive for a number of reasons. One could simply be slightly altering the tonal balance with a fuller bass, so it can sound more complete at slightly lower volume levels, or you feel the bass more at the same volume levels as the old version, giving the subjective impression it’s moving more air at the same volume level.

I’m sure there are other technical aspects understood by others for why a speaker may sound more sensitive than it actually is.

I have a pair of Waveform Mach MC monitors, rated at only 84.5dB sensitivity. But they sound more dynamically alive, within their frequency limits, than pretty much any other speaker I own, including higher sensitivity speakers.

Do you have the Talk Talk album Colour Of Spring?

If so try playing the first track. It’s one of my test tracks for speakers. The production and sound quality is amazing and that track is great as it starts with a pristine drum beat and individual instruments come in.

I played that track on the Perspectives at my house and honestly thought “I don’t know if reproduced sound gets better than this!”

It is on Qobuz at 24/96. Sounds very good
