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

I wish I could provide some real help for you, but it's my opinion that speaker placement (and lack of acoustic treatment) in your listening room will hinder the performance potential of any speaker you buy...even more so than your electronics. That said, I feel that good soft dome tweeters are better than any metal dome tweeter, and you might want to give some of those a listen sometime. Companies like Dynaudio, Nova, PBN, Meadowlark, Merlin, all have smaller speakers in your price range. If you'd ever consider buying used speakers, you can get a hell of a lot of speaker for $1500. My Paragon Acoustics Radiants are perhaps the best speaker value anywhere, especially if bought used, like I did. Let me stress again, an untreated room is NOT a listening room! Good luck.

I agree with most of Carl's suggestions, and i would like to add. that placing speakers, along the "long side" is correct placement. I am not familiar with potential, of your amp, but i would try fallowing speakers: Meadowlark shearwater (used), Legacy "classic"(used)Celestion A2, and Linn "Keosa" (new).

I'll share some experiences as a NHT 2.9 owner: 1) 2.9s go very, very low - enough to clear your sinuses, enough to freak out small animals...way fun! 2) Placement is EXTREMELY critical with the 2.9s as well as the listener's distance from the speakers. Check the owner's manual on speaker placement at www.nhthifi.com before buying. You want to be at least 9' away from the front of the speakers. 3) You cannot satisfactorily drive the 2.9 with a receiver or even with an entry level high-end amp, you must get premium amplification if you don't want to be fatigued - remember, the NHTs put out what's put into them and they are unforgiving about it. I tried the Adcom 555. 555II, and 5500, and none of them worked with the 2.9s. Tubes are key - I'm now using a Counterpoint SA-220 with good results - all day listening sessions without fatigue. If you are willing to spend some more dough on audio equipment and play with speaker placement then the 2.9s are magic, but I think you should go for the Thiels as their more 'traditional' design allows for some placement flexibility. Good luck!

Woodmann is absolutely right. The NHT's require the best amplification. I am with him on their use with tubes. I am using all ARC tube amplification with the 2.5i's which are very similar to the 2.9's but lacking somewhat to the 2.9's ease in the midrange and the low bass though you won't be unsatisfied with the 2.5i's bass (29hz at -3db) It is clean, well defined and better than anything I have heard in their price range (1300.00 retail). Warning! Do not go with the 2.9's if you aren't committed to better amplification. Ultimately you will be unsatisfied. If you are willing to spend the money, you will be hard pressed to find any dynamic system that offers better transparency, dynamics, low end performance and unfatiguing music. They mimic the recording good or bad. To me they offer the most that you can ask for in a speaker system PROVIDING everything upstream is excellent.

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
