looking for a stand mount speaker to match a s/s int amp.

Hello all  , happy to be back at this hobby.

Just acquired a Classe Cap 151 ( 150 watts at 8 ohms/ 225 at 4 ohms )

( Panasonic DVD-A ,Harmonic Technology Fantasy speaker wire & HT Truth Link I/C)

Looking a used stand mount speaker to match my amp , low volume listening a must .

This system stay in my 12 ' x 15' 1/2 room.

My budget is limited from $500 but can squeeze up to $800/1000

Here a few that  I like but never audition , so I am depending on your honest advise.

1. Nola boxer 2

2. Von Schweikert VR-1

3. Vienna Haydn Grand

4.open ...??

  A good sounding n musical speaker  can be driven with  my cap 151 & tube integrated amp

 in the near future. I listened below 9' 0 clock or 1/2 from zero , mostly at night time.

I thank you all in advance. pescolar
