Short answer: the Aperion Audio Novus N5T. Both are rated 3.8/5 for sound quality (#154 and #153 of 228 floorstanding speakers), and the Aperion Audio Novus N5T costs $1,048.50 against $11,090 for the Vandersteen Treo CT, and with sound quality even, the cheaper one is the better buy.
Why pick the Aperion Audio Novus N5T: A compact direct sale tower with a warm tilt, deep bass, smooth in-room sound and a home trial. Watch for: The -0.31dB-per-octave response tilt makes it moderately warm/dark, while on-axis smoothness of 0.267 is merely average.
The Vandersteen Treo CT is the deeper-bass choice. A time-aligned four-driver tower with exceptionally deep bass and smooth sound spread through the room. Its bass reaches about 43.9Hz before falling 3dB, against 51.3Hz for the Aperion Audio Novus N5T. The tradeoff: At $11090 per pair, 80 lbs (36.3 kg) each and only 85dB sensitivity, it is costly and amplifier-demanding.
Buy the Aperion Audio Novus N5T. Both are rated the same for sound quality, and it costs $10,041.50 less than the Vandersteen Treo CT.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
