Re: NSI - the first impressions

No reason why we couldn't run an NSW with the preamp outs, right? Yeah, there is reason not to connect the preamp output to a NSW directly. Because the NSW gain doesn't match the NSI gain, it will cause mid-high/woofer imbalance. Assuming you are thinking using the NSI to drive the upper or full ra...

Re: NSI - the first impressions

:shock: that’s one hefty looking unit!! Biff Your AG8100 shares some very similar design with the NSI. Remember when I wanted to go as far as you would let me with your AG8100 earlier this year. I was designing, building, testing and back to drawing boarding on the NSI along side with your AG8100. ...

Re: NSI - the first impressions

The rear end. Three line level inputs. One BAL and two SE. The third pair of SE output is the preamp out. I put that in for my own testing purpose and may be someone can use it to drive sub woofers.

And here is a pictures of the NSI-G, the super NSI as George has been calling it. It measures 17.25" wide x 14.75" high x 21.5" deep plus the binding post. I can make it in smaller multiple boxes.

Re: NSI - the first impressions

Great review George!! Hey, can you snap some pics of the amp and post them here? Also, it is great to see GilBut offer the Tube/SS summing circuit that he built into my custom 2K4sh - it truly gives you complete control and on mine I can completely shut off the tube section (which is 6SN7 as well) ...

The not all new but new enough BC515 Digital to Analog Converter

For the past three years I have been thinking about designing an all new DAC. After looking at what material are available to design new DACs and what are currently available from other companies, I have decided designing an all new DAC from ground up is a total waste of time. At least from a music ...

BC1002-ML stereo power amplifier

Here is another new power amp this year, BC1002-ML. When I designed the BC1022 many years ago, I was going to make a little brother along with it. However, due to marketing and other factors, the little brother has never come to live. Since I am semi-retir........ing. It means I am going to do what ...

Re: PLC FX2 X0E and other questions

olddude If the PLC is brand new, it may take up to a month for the gas to stop. Make sure you garage has good ventilation. Otherwise, it may take longer for the gas to stop. Having a fan blow right onto it will also help. Keeping the temperature above 15C will also help curing faster and therefore s...

Re: A New Power Amplifier Prototype

masluck I don't know I would consider myself a tube guy from an audiophile point of view. I like the sound effect from tube but don't want the hassle (hiss and noise) and maintenance cost of tube. Especially power tubes. So you will never see me designing a tube power amp. I am using less number of ...
