My friend has their biggest model driving with Pass 200.5s, Conrad GAT, AR CD-8, MIT Oracle ICs, Transparent MM1 Ref SCs, and all top of line Synergistic PCs. He is a very nice guy and will demo it if you contact him. He is located in Arlington, TX 76001.
The flagship, I may be wrong but I think it is NTT-101, speakers are quite large (over 1200 bls. each) and require a large room for the best but you can get the smaller version that works for your room. These will not only give you WOW factors for the look but the sound is unbelievably impressive. The clarity, the resolution (each instrument and each note are crisply), and instruments separation (youll hear the drummer to the far left, while the piano plays to the right, and the singer is dead on centerstage) are top notch but what struck me the most part was the spacious and airy with the REVERBERATION effect. This gave me a sense of being in a wide concert hall with a very tall ceiling, almost like a church sound effect.
Secondly I was blown away by just how effortless they sound with any types of music from the lowest octaves on up through the highest of highs. The sound and sound pressure levels are just inspiring, dynamically is one of the best, the bass reproduction has speed and notes that most of anything out there cannot match. You can crank this speaker to crushing sound pressure levels and it will never lose its grip and remain fidelity. This is also true at low volume.
Finally, if you are looking for towering soundstage, look no further. Its soundstage is wide and deep, closer to the scale of a large orchestra or a full organ.
As always, matching components to your taste is the key.
