Not Another NuForce thread......

Ok, first I am not shill or related to, or affiliated with NuForce in any way...I just thought that we should have a thread to discuss the V2...

I just placed the Reference 9 SE "V2" in my system after living with the NuForce 9 SE for the past year and auditioning the Reference 9 V2 for the past 2 months...

I am putting out there for comment and debate that the Reference 9 SE V2 is one of the top 5 best amplifiers out there and currently available. (I personally think that it one of the top 3, but I am leaving room for argument)

Sitting in my room last night I was reminded of one of those transforming audio experiences. My first ones was couple of hours with the Sinus Faber Amati Homage pushed with a full compliment of the top of the line ML gear all with in a perfectly treated room....My experience with the Reference 9 SE V2 was like that...

Please comment if you are able on the V2 in general, what was your experience?? Are your thought of the Reference 9 SE V2 the same??

My experience is with the integrated. I owned the original 50 watt v1, then upgraded to 100 watt v2, then upgraded to v2. I think the v2 is cleaner, clearer sounding, and more extended on top; possibly more extended on bottom not sure. Overall it is very noticable and I cannot hear any sonic downside to the upgrade.

Oddly the unit seems to get hotter on top than it used to. I read some place that with v2 on the integrated, the heat is redirected to the top of the unit instead of the bottom, for easier dissapation. I ran the unit 48 hours at substantial volume to break in some Thiel 1.6's and it got pretty warm. Not too hot to touch, but noticable. I do agree that venting the heat on top is better. I am surprised that a class D or class T or whatever would get so warm (It's not class A, right?). Anyway, I don't know if the monoblocks will have the same characteristic or not.

I recently left my V2 integrated on for 72 hours straight, driving Thiel 1.6's for breakin (3 ohm min), and found that there was a little residual RFI interference on cheap FM tuners by the end of that period. Perhaps the long time and heat build-up changes component spec just a bit. My high quality Denon FM tuner is not affected at all but $30 clock radio had a hint more static at that point, which disappeared when I turned the integrated off.

However when I first turn the V2 unit on, there is no static even on the cheap FM radios (unlike with the V1, where the cheap FM radios were unlistenable immediately upon turn-on of the NuForce).

This is my long way of saying that I've decided to NOT leave my NuForce integrated turned on 24/7. Usually with solid state, I do leave it on 24/7 unless it has a high bias to class A.

Often a thin sound is due to underpowering; that is, given the efficiency of the speaker and the size of room and your musical taste, more power may be needed. Sometimes we think we have enough power just because we get volume....
