Would Totem Arro's be a significant upgrade from Kef Q150's


My listening room is on the long/narrow side 8' x 18' x 8' high. Therefore I listen in the nearfield, speakers (Kef Q150's) are 5' apart and myself 7' away from them. I very much enjoy the sound I'm getting from them. My setup is Yamaha A-S501 with chromecast audio going into the optical input, streaming Spotify premium. My speakers are 2' away from the rear wall and I find the bass is plentiful that I don't use a sub woofer. I have the opportunity to purchase a pair of used Totem Arro's which would work in my room as far as tower speakers are concerned. I am quite happy with the sound I'm hearing now, but if this would be a significant improvement I would purchase the Arro's and sell my Kef's. Type of music I listen to is a lot of acoustical, alternative/indie, a little classic rock.

hey. I had the Arros fora while. They image beautifully, but they're not the most bass-y speakers.
The answer is only yes if you're prepared to upgrade the amp.  

Nothing wrong with the Yamaha integrated amps in general but the Totems will demand a better amp from day 1 that you own them.  They'll sound a bit dull and lifeless until you up your amp game.

Hi Helge, I don’t know why I can’t reply directly to your private message, because I am getting an Audiogon “error” alert.

Anyway, your question was:

I currently have Totem Arro speakers and am contemplating the Model 1 Signature bookshelf speakers. Am curious If you are still using them or moved on to something else?

In my opinion, if you have a capable amp (or think about getting one) you should go for the Signatures. In comparison with the Arro, my Model 1 is a more evolved and sophisticated speaker, capable of better imaging and soundstage, and more depth and bass delivery. The Signature should be at least the same.

Oh, and is crucial to have heavy 24in height stands. I have the mighty Target R4.

I hope this helps :)

Cheers
