PS4/Nvidia Shield --> Marantz AV7701 --> Emotiva XPA-5 --> Ascend Acoustics Sierra Towers and Horizon Center w/ RAAL tweeters (L/C/R), HTM-200 SE (Surrounds), 2x Rythmik F12 subwoofers
I don't know of any soft dome tweeter at any price that can compare to a RAAL ribbon tweeter with regard to detail, timbre accuracy, smoothness and overall musicality.
An update in case anyone was interested. I am now powering my S2's with a 25 watt amp. I wasn't sure how it was going to turn out but they sound great, maybe even better than my main system (with a power amp).
BTW, I started with a pair of 200's for convenience - new stereo in new room. I've had 200's as surrounds for years but never really ever have just listened to them. I have to say I was impressed. But they still went back as surrounds and moved the S2's in when everything was ready. I could totally see having a nice 2-channel system and using 200's.
Here's a review that I just posted to Audiogon - hope it's okay to just copy and paste it here - I'm really impressed with my Sierra 2's.
I case anyone is still thinking of getting the Sierra 2's, I'll add my two cents. I've had mine about three weeks, and am very impressed. Right off the bat, I thought they seemed a little bright, but either they've calmed down after burning in, or my ears have adjusted. Part of the adjustment is that they just give you gobs of detail. Probably a little of both. And the bass response in tight, and tuneful - and plenty for me. And probably my favorite thing is they sound fantastic at lower volumes, as I live in a condo.
Rega Elex-R amp
Mostly lossless digital files (some 320) from either my iPod classic, or computer.
Highly upgraded Rega RP3 w/ Rega Exact and Rega MKii Fono amp
Speakers I've either owned or auditioned in my home in the past few years:
-Monitor Audio GR10 - pretty amazing paired with a NAD 326 amp - fantastic bang for the buck.
-Epos Elan 15 - seemed kind of dark - didn't keep for long
-Monitor Audio GX100 - nice, but always sounded like you were listening to a speaker - not very transparent.
-Totem Acoustics Rainmaker - way too bright with my amp.
-B&W 685 S2 - Great bang for the buck - great with digital music, but I didn't care too much for them with my vinyl - a little too warm.
-Dynaudio Excite X-12 - the best I had until I got the Sierras - great imaging, tight, punchy bass, and good detail in the highs.
-Dynaudio Focus 160 - hands down the best tweeter (but the Sierra's is very, very close), but the bass response seemed kind of flabby and unfocused.
And it certainly doesn't hurt that the Sierra 2's are drop dead gorgeous. I got the B-stock satin espresso, and I have no idea why they were b-stock, because they look flawless to me - and I saved $300.Hope this helps anyone else thinking about getting a pair - I think they punch way above their weight.
Side question, nothing to do with this thread - I had work done in my place and the contractors somehow dinged up my speakers in a couple places (there was no reason to be anywhere near them) and now the...lack of stain I guess...in those places makes it very obvious - is there a way to fix the satin expresso finish up?
