What could be the differences between the Spendor A4 and A7 in terms of sound quality?

Sorry...PL = primaluna :)

I’d think PrimaLuna would sound nice with A series, but haven’t heard it to verify.

FWIW, I use Audio Research DSI200 integrated amp with my D7’s.

I think both the A and D series are not too difficult to drive; pretty easy impedance curves as noted; not extremely high sensitivity ratings but decent.

As you probably know, A series doesn’t come with grills, so the drivers are exposed. I find that the A4 looks kind of strange because the mid-bass driver has a somewhat truncated look (don’t have full circle of material surrounding the driver - like sides are shaved off), almost like the cabinet is not quite wide enough, but that’s just a personal aesthetic appearance thing -- probably some people think that looks cool.

@glow_worm Thanks for clarifying that out lol There seems quite a number of used PL tubes out there and I would love try them out once I make the decision on speakers.

@kren0006 Yes, I noticed the A4s have the woofer edges cut out to have the cabinet shape. I thought it was okay, but seemed a little compromised sound-wise, externally. I’ve just read your posts about the A2, A4, A7, and D7 in other threads btw! Great help.

I assume that it’s just an appearance thing. Can’t imagine that would affect sound. Just looks kinda strange to me. Minor detail 

Agree about the A’s appearance. Vinyl Sound makes grills for $189 I’m considering https://vinylsound.ca/products/splendor-a-grill
Magnets attach to woofer screws, I assume the sound would be unaffected but can’t be sure.
