Hi Sasha,

How are you? Do you still remember your Chinese customer?:p
3 month passed and I'm very happy with the vtf-3. I use it mainly for listening to music, and never turn it off. I noticed that in its stand-by mode, the rear panel is a little bit warm, will this be harmful to the electronic parts for a long run? I heard that it's designed to be in stand-by mode and don't need to turn off every time, is that right?

Also, I'm thingking to buy and Radio Shack sound meter and HSU High Pass Filter and hope this can improve the performace of the whole system. What's your suggestion regarding this?

If I decide to buy the high pass filter (with 220v 50hz power), can I pay it with my Visa and you send it to my friend in Houston so that she can bring it to me when she come to China?

Since I'm using a mini bookshelf loudspeaker, the crossover that I set the vtf-3 is around 60hz, is this a reasonable setting? Considering it's a small speaker, I tried 70hz, but sounds not as good as setting to 60hz. So if I buy the high pass filter, what the crossover would be?

Looking forward to your advices.

Thanks and have a nice day!

Xin Liu

Its great to know we have happy customers, even in China! The standby mode uses about 5 watts of electricity--about the same as a big nightlight. So, because of this current draw, it will still generate heat. As long as the VTF-3 is positioned upright so the air flows through the heatsinks, everything will be fine.

A trained ear can do the SPL adjustments using pink noise, but a SPL meter is a useful tool. You can really get precise measurements about the integration of the mains and sub.

A high pass filter, which is probably available in China, will help relieve the load on your amp and main speakers, possibly allowing for a noticable difference in sound quality. We are temporarily halting our international shipments, but I am sure you can get a high pass filter in China. I would get it set to 80Hz.

If the 60 Hz sound better, use that. Your ear is the final judge of how the system should be set up.

Recognize this picture?

So the little warm should fine. ;)
I'll ask my find get a radio shack sound meter for me from the states. Also try to find a high pass filter from local hifi store.

Thanks,
