Oh, it's nothing special. I've got 2 pairs of bookshelf speakers from the last Infinity Reference series, aka "Baby Revel's", and inexpensive, but transparent, Class D amplifiers. One is used in an AV setup, although mostly for music, and the other for a desktop system.

People refer to the last Infinity Reference series as Baby Revel's because, both Infinity and Revel are owned by Harmon International, and they share design philosophy and technology to a certain extent.

One, the Infinity Reference 162, is comparable in performance to the Revel M16. They just can't play as loud as the latter without audibly distorting. However, they're clean up to ~85 dB and I never, ever play them that loud under normal circumstances.

The other, the Infinity Reference 152, which I use for my desktop, is comparable in performance to the Revel M105, with the same limitations as I've mentioned for the 162.

Both pairs are frequency response corrected and tuned to my listening environment via DSP.

All the best... 😎
