speakers for arcam integrated

Quad dynamic speakers (L/L2 series) are magical with Arcam IMO.

I'm sure that by now you might have settled on a pair of speakers for your Arcam amp.

But, if you haven't and for other interested readers, audition the A38 with a pair of B&W 805s. Or better still, if you can get them, a pair of B&W 705s. I have auditioned an Arcam A18/P38 combination with both the 805s and 705s and was impressed. I liked the sound of the 705s better, but that's probably because I have those and am used to the sound they produce.

Not sure of your budget or room size, but I've heard entry level Dynaudio monitors paired with Arcam @ a local dealership that sounded nice, and also own some old Dynaudio Audience 42's paired with an old Arcam integrated in my bedroom system. The Vandersteen 1C's are also a high value speaker that might work well, if you are okay with their appearance.

Great amp--they sound very sweet, not a negative, but musical comment. My first high end gear was the famous, A-60 Arcam.
Could you share a budget?? Sometimes setting the price without knowledge of what your dollar buys is a frustrating experience.
In the $1K price range floor standing, the Vandersteen 1C. It's kind of a no brainer. Some may not like the Cloth exterior, but that's another subject. 38Hz bass, and very efficient at 90db1W1M.
For a Bookshelf, excuse the excess for recommending my LSA's in Rosewood--at the same $1K. Very attractive, (high wife factor). They MUST be biwired, (doesn't have to be expensive, just bi wire--they don't sound anything like they can single wired.) I only made them strappable to make them easier for initial hook ups for newb's.
Either speaker will give you great fun and sound.
Good listening,
Good luck,
