Re: AA Sierra-2EX Monitor Review
My Background: Musician and Engineer. I've played some combination of trumpet, guitar and keyboards since 2nd grade. Engineer is day job: Combination of computer hardware and software design.
I've had my Sierra 2EXs for 1.5 years now and I thought I'd chime in on their performance. I'll follow Ted's original review format and add my own comments. My setup with the Sierras is Moode Audio running on a Raspberry Pi 4b, streaming into a Topping E30 DAC in pure DAC mode into an Academy Audio preamp then into dual mono Hypex NC400s into the 2EXs.
I've owned two audiophile monitors sets since I started in the hobby 20 years ago. Both had exceptional imaging, dynamics and richness. The first were Dunlavy SM1 studio monitors. The second were Alon Acarian 1s. The SM1s were the fastest, best imaging monitors I'd ever heard. Amazingly the 2EXs almost exactly match them in that respect.
The Alon 1s are dipoles and have the most amazing holography with the ability to project the sound stage behind you. With well-recorded live music the 2EXs equal if not exceed them in this respect. I tested the 2EXs with an ambiphonic recording of a nature setting with birds flying around a lake and the room became the lakefront and I was completely surrounded. I could identify individual birds and their species as they slowly flew by. Stunning.
So in my mind the 2EXs are like a combination of a Dunlavy SM1 and an Alon 1 with tighter, more extended bass -- except, and this is totally subjective, they are more musical. I think its due to that amazing RAAL ribbon tweeter and its almost magical cohesion with the Seas woofer creating accurate sweetness combined with rock-solid pacing
That tweeter is so accurate, but never harsh. Bells sound exactly like bells. Saxaphones and trumpets are sweet and accurate. I have a few recordings that mix trumpets and cornets and you can clearly hear which is which, who the the manufacturer is and what kind of bell they have (76 LA Benge and 1934 Olds Standard for the curious). Guitars are airy and sensuous.
I listen to about 70% Jazz/Fusion, 20% Rock and 10% classical. One of the first albums I tested was Bob Curnos LA Big Band performance of Pat Metheny and Lyle Mays tunes. It really stretched the 2EXs and they shined. Reproduction of complex human vocals and acapella is amazing in Cadence's renditions of Feeling Groovy and Spinning Wheel. Turn on the 200 wpc NC400s, give the 2EXs enough juice and they rock out without break up (be careful). Spin some Yes/Fragile/Roundabout, RUSH (anything) or early Chicago (Brand New Love Affair, Dialog Parts 1 and 2) and... wow. Energy, dynamics, separation and pace all day long.
So I love these things more than some relatives. No they aren't free, but they *are* a great deal on a slice of sonic bliss and an example of great craftsmanship so rare these days. Thanks Dave!
