the high end vintage KEF's are highly rated & very affordable. a set KEF104ab just sold on CAM in Quebec for $215 - alot of sound for very little money indeed!
i just returned from an audition with the 25yr old (dont know if that counts as vintage) NHT 3.3 with my own DK integrated amp.
1.my amp drove the 3.3 extremely well extremely loud - we measured 120db on track just to test the dynamic range of the speakers with my amp
2.bass was incredible! alot of ppl use "Hotel California - Hell freezes over" as test track for bass response dynamics. i can safely say i have never heard the kick drums thunder this hard, this deep with this much impact! it was crazy.
3.the 3.3s are very detailed & revealing
4.the 3.3 is truely a full range speaker
5.the 3.3 is the least fussiest speaker to setup besides the Yami NS1k in my experience. we had the 3.3 directly vertical & placed 3"-5" from back wall with atleast 3ft from any side walls. i wish all speakers were this simple to place.
1.i could detect a slight sibilance on some tracks
2.soundstage though intimate, can be small at times
3.soundstage depth is definitely its weakest area
no time nor opportunity to determine causes of sibiliance. it could be speaker (it would seem aluminum tweeters are well known for sibilance) itself or the cheap cable we used or the source or perhaps the speakers are so revealing that it shows the recording warts & all.
based on my short time with the 3.3s i can certainly see how bass can be light, highs can be thin or even harsh if the right ancillaries arent synergistic. however with my amp, this pair of NHT 3.3 has some of the biggest & best sounds i have heard. the mids are as detailed, as clear, as musical as the beryllium mids of my Yami NS1k. the bass is simple....INCREDIBLE, big huge & deep. the highs are very extended & detailed but with a penchant for sibiliance & its precisely this that i am concerned about.
i can safely say its not my amp as the same amp on the very revealing NS1k is not sibilant. but all in all, the NHT 3.3 are very impressive speakers & does seem a great deal for the money. now its down to working the fine details as its likely that i will be an owner of these 3.3s. theres a possibility that we will do a trade of my ET lft8b hybrid mag planars for the NHT3.3 as well.
