Help deciding between two speakers.

I am trying to decide between a vintage pair of infinity rs iiia and triangle borea BR08. I will have them in a large open living room and I listen to rock, pop, and country music. I will be pushing them with a pro-ject audio rs amp. The infinities are legendary speakers but obviously are older and may need to be refoamed. The BR08‘s are new. I will save a few hundred going with the infinities. Is there a big leap in speaker quality between the two? Are vintage better made? Any input would be greatly appreciated. I should also say I am not looking to blow the doors off the house. I am looking for great sounding and detailed sound. I am open to any other suggestions. There is no particular reason for these two other than they are in my price range of around 1k and they are available in my area.

the room they will be in is 20x30 with a 10’ ceiling. And the specs on my amp are as follows.

Tube assembly: 2 x ECC88 (6922)
Power output: 2 x 110W / 180W @ 8 ohms / 4 ohms
(2x 180/250 W @ 8/4 ohms with PS Box RS)
2 ohms drive capability
Frequency response: 20Hz - 50kHz (- 0,8dB, - 3dB)
Signal to noise ratio: >-100dB (IEC -A)
THD: < 0,05% @ 100W
Input: RCA & XLR-sockets
Input sensitivity: 1,35V
Input Impedance: 22kohms
Speaker terminals: 4mm Ø Banana, spade or bare wire
External power supply: 48V/2,5A DC;100 - 240V, 50/60Hz

Thanks in advance for your input and again if anyone has another suggestion please let me know.
