I'm from Hong Kong and really interested in new IA-7 V2. It give me a shocking performance at this price!

The new version IA-7 with 4 RCA inputs but without "booster off". If I use it as a pure preamp (config 4th RCA input as preout) and without connect to speakers, will it cause any problem at no load condition?

Can I just simply disconnect the cables from power supply to V2 boards to perform the "booster off" function?

The reason why I use it as a preamp because I have both passive and active speakers in my home.

Please don't open the unit and mess with it.  The preout allows you to use the IA-7 V2 to drive another amp for bi-amping. But you should have the speaker connected at all time.
You should not use it as a pure preamp.
Our P-8 is a very good entry level preamp (IA-7V2 preamp circuit comes from P-8).

Thanks Jason!

In my case, I think old version (with booster off) is more suitable as I can use it as a pure preamp  .

Does the old version still available in silver colour?

No, the older version is only available in black.  You can try to locate a used silver IA-7 and send in for upgrade to V2.

Jason, unfortunately there's no ditribution of NuForce in my country, should i send you the amps? Or you just send me the modul of V2 and i'll setup them by myself. And how about the guarantee after my amp have been upgraded?
