Tubes or Sand for Totem Arro under 1k?


I'm building an office system around the Arros and need an amp that will make them sing at low volumes. The volume must be kept low as I'm on the phone most of the day in my 12x15 office. I love tubes, but am concerned about heat. How about Audio Analog Puccini? Pathos Classic original?

Your thoughts are appreciated.

I just picked up some Arros. Has anyone experimented with mass loading? sand or lead shot, amount?

Thanks
Douglikesaudio, I have arros paired with a Cayin TA30, and the sound is excellent!

Rrekstad, I haven't experimented with mass loading, but in conversations with Vince, he stated that while mass loading benefits the bass response, it comes at the sacrafice of soundstage. Kind of left me without the desire to experiment...
Haven't tried mass loading for the same reason as Jh2os. I like the soundstage wide and the sound lively. Seems a light but rigid cabinet does these things well!

As for my amp, I ended up with an ASL Orchid. 3.5 watts of low volume musical bliss.

Enjoy.
