Short answer: the Arendal Sound 1723 Tower THX. It ranks #74 of 226 floorstanding speakers by sound quality, rated 4.3/5, at $4,200. The Monitor Audio Silver 500 8G ranks #105, rated 4.2/5, at $4,000, $200 cheaper, which does not close the gap in sound quality.
The case for the Arendal Sound 1723 Tower THX: The large tower of Arendal’s THX Ultra certified 1723 series, with a 28mm tweeter in a waveguide and four 8” woofers in a 2.5-way layout. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured 1723 Monitor THX.
The case for the Monitor Audio Silver 500 8G: The largest Silver 8G tower, with two 8” C-CAM bass drivers, a dedicated 3” C-CAM midrange and a 25mm Gold Dome tweeter (crossovers at 640Hz and 2.8kHz). The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Monitor Audio Silver 50 7G (a 5.40 Spinorama preference score) and the 8G range.
Buy the Arendal Sound 1723 Tower THX. It is rated higher for sound quality, and saving $200 with the Monitor Audio Silver 500 8G does not make up for the sound-quality gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Arendal Sound 1723 Tower THX 4.0 to 4.5; Monitor Audio Silver 500 8G 3.8 to 4.5). Treat this verdict as provisional.
