Help me choose: Harbeth 30.2 or SHL5+ XD in a 10 x 13 feet room?

@yogiboy I sold my Super HL5 Plus 40th some time ago, preferring the C7s over those.  I've also owned Stirling Broadcast LS3/6, and no longer have those either.

I have owned P3ESR SE speakers for a few years, and have always kept those in a second system, thinking they were too small for the main system.  After hearing the Falcon LS3/5 2024 Limited Edition at a friend's house, I decided to try the P3ESRs in my main system.  My room is odd shaped and opens into my kitchen / dining room, but it's a fairly large space.  They sound fantastic in there and may not leave.  They are augmented by 4 subwoofers, so there's that.

I will say that the Falcon's were really amazing, providing much more detail than the Harbeths.  They were fun, but the Harbeths have plenty of detail and are so easy to listen to.

In that price range, I would also consider the Fyne Audio bookshelf speakers, particularly the F-701 and the F1-5.  I have the floor standing G-702s, and the sound quality is superb, and the two mentioned should be superb with a subwoofer(s).

My room is almost identical to yours. I am running Harbeths 7ES3 on Luxman amplification and JL Audio E110 sub. I couldn’t imagine “more” speaker in my room. I have kicked around the idea of going to the p3esr but am afraid I would lose the “big” sound of the 7s. Good luck in your decision! 

Have a look at the much more flexible EPOS ES-7N which allow for placement close to a wall or more open placement. I find the Harbeths rather flat sounding. For the past two years the EPOS models have received great reviews and are much less expensive than the Harbeth - https://idc-klaassen.com/en/tests/epos-es-7n-what-hi-fi-award-2025-in-the-gbp1500-gbp2500-bookshelf-speaker-category/
