I think this means you're officially one of us. Frankly I think the classic S-90D is way more interesting than a sub, and I'm curious how you like them. Plus, sub bass is actually a lot less important to the enjoyment of music than the voice of a speaker (my own sub lives in a closet under the stairs, not used for years), but this is the sort of thing you need to learn on your own, and trying different speakers will help you learn this in a very fun way.
Hooked them up today, and well... I love them! I regret nothing, it sure was a worth purchase, even if I ended up paying 200 Eur for them (those for 160 were sold), but these has better visual, less wear.
The sound is great - it's clear, bass is warm, high frequencies are crisp and when a female vocal plays it's the ultimate sensation to my ears!!!
Those sub bass frequencies I was wondering about - I mainly listen to jungle music (for those who don't know - a predecessor of drum and bass, only produced with a lot more soul and effort put in), and some tunes have some deep bass lines, that i was not able to hear on my previous speakers, nor on any modern, common, commercial gear. So it was just silence where a groovy bass line should be. Well the S-90D's passed the test, successfully plays the bassline and I can hear the whole tune finally! I guess i was wrong about the exact frequency of the note, it just sounded really deep to me. So yea, changed my mind about the subwoofer - won't buy it - not necessary.
Hooked them up to my Pioneer AZ-470 amplifier, or perhaps it's more likely a receiver, cause it's a part of a hi-fi deck - speakers are playing good, but i have a feeling, that my amp is underpowered for S-90's, although I didn't notice any clipping, but i know that those speakers have plenty of potential left. The amp is rated 70w per channel / 8ohm. And the S-90's as we can see above are 35w, well, crap, i have no idea how the soviets are measuring power, nor do i know how pioneer is measuring their power. I guess When looking at amplifiers, i should read the S-90's as 90watt speakers. (except for soviet ones).
Anyways currently my speaker amp combo works nice, i just hope the amp isn't clipping. S-90D's has LED overload indicators - would they light up in case of an amplifier clip??

Sooo, yea - i'm very happy about them. Actually there is one thing i regret - not buying them sooner.
I don't know, maybe to some hard core audiophile they would seem like a regular pair of speakers, but well, for me, after all my cheap ass speakers, these are superb, i like them very much.
Pics coming up in the next post.
