NHT 2.9 vs. Thiel 1.5 (or other?)

Hi, I own a pair of NHT 1.5. I am looking to upgrade to a more full-range pair of speakers and still to have some room left for me in the apartment after that. The electronics I use is a Sony 333(?) ES receiver and it's 24/96 built-in dac which I find superior to the DAC in my CD player Sony CDP9 ES. I listen mostly to acoustical instrumental/vocal music (classical, jazz, alternative and the like). My room is approx. 14 by 26 (with dining area in it, so effectively 14x20) and I can only position the speakers along the long side of it. Could give them up to 2-3 feet from the back/side walls. I recently auditioned the Thiel .5 and 1.5 side by side with Vienna Acoustics Bach and Magies 1.6. To my liking the Thiel 1.5 gave me most satisfaction (Vienna had boomy base, Magies had somewhat less precise high end and very narrow height of the sweet spot and also very low efficiency plus the bipolarity may be a problem). The NHT 2.9 has supposedly lower low-end (29 Hz) compared to the Thiels (42 Hz). The problem I have with my NHT 1.5s is that, even though they are exceptionally clear and accurate, they sound fatiguing to me and I suspect the larger 2.9s may be similar. I understand that this may be due to the electronics I have, but that’s the $$ situation right now. Can anyone provide advice primarily on the choice between NHT 2.9 and Thiel 1.5? Other suggestions will be appreciated too but should not exceed $1500. Thanks, Mihail

Thanks! When you mention good amplification, at how much $$$ do you think it starts at (perhaps used) to be good enough? Could I reuse the pre-amp section of my receiver (it has pre-amp outputs for all channels)? Or perhaps use the receiver for the one half of a bi-amp setup? I appreciate your responses. Mihail

I recently purchased a pair of 2.9s trading in my Thiel 2.2's. I have biamped the speakers using NHT's SA-3 subwoofer amp and an Ayre V-3 on the top end. My dealer sold me the SA-3 for $300 and I bought the Ayre used. It is a great combination but you definitely want something smooth (tubes or tube sound sounding solid state). These speakers are incredibly dynamic with really extended bass and I think are one of the great unknown bargains in high end. Like the comments before me, yoy would have to upgrade your system to work well with these speakers

From my experience, I would say that Thiels can be as UNforgiving as NHT's. If your current system is a little fatiguing with the NHT 1.5's, I would predict the same or higher level of fatigue with EITHER the NHT 2.9 or the Thiel 1.5. I am wondering if your audition of the Thiels wasn't with some considerably different equipment than your system? If ask me, the Sony receiver is the real weak link in the system. I have generally found Sony ES receivers to be a bit on the bright side to start with. So, you might consider and NHT sub for the extra lows you want, and maybe a tube integrated for the 1.5's to get a more rounded and easy to listen to sound. The NHT subs are actually quite good, and there's a BIG bonus for your situation - the sub is easier to place in an ideal spot, plus it has more spots that might be ideal. The one thing I can tell you for sure is that both the 2.9's and the Thiel 1.5's are placement picky, which may be a concern given your room. Oh yeah, stay away from the maggies if you don't want to have to replace the receive immediately - they will not be happy with that receiver at all. The other two speakers have a better chance of coping with the Sony.

Thanks again. I'm getting convinced to upgrade my electronics and use the NHT 2.9 ... It is unfortunate that there are so few Thiel dealers to let me audition at home.

I have 2.9's. They are great speakers you have to be care full with amps. I found these to be too bright with a Bryston 4bst. I now use a Classe ca200 and it is a really nice match. The dynamics of the 2.9's make up for the sleepy nature of the Classe and vice versa. These speakers will sound really bad with Sony.
