Yes, I was cheating

The driver tube is a 10Y, usually a power tube. Not a sissy by any means.

BTW, this is one signal chassis of the GM70 amp, there is a another similar chassis for the right channel, and a big chassis for the power supply. Nelson would need a shrink ray to fit inside the S2 case. And the GM70 system weights about 5 times the S2, so an anti-gravity belt would also be required.

Hummmmm, that bag is in the S2. Now I have to wonder.

Default A little more listening

The amp continues to surprise me. In some ways it sounds very much like a tube amplifier, but not altogether. This is just a brief note, as my reference speakers are not available and the speakers being used are not of extreme resolution.

The amp sounds "big". There is a large, open soundstage that fills the room, that is the first thing that you notice when the amp is plugged in. The effect is a little intoxicating.

Then there is the control. My usual collection amps never brought this particular pair of speakers to life. (I have been playing with a EconoWave like speaker to see what I could do with it). But the SIT seems to bring a lot more control & detail to the speaker.

Sarjan has noted, the speed is obvious. Although the initial reaction is that it is too fast, you begin to realize over time that the other amps are a little slow. Real music can be very fast, especially with the close miking that is used for most modern recordings. Sorry ZM, I do not know of any tube amp that can do this, so I do not think NP stuck a 300B in there.

The tube sweetness is present, yet the presentation is very clean. This is like a very nice low distortion SET.

The one thing that Sarjan missed, that I find very important, is the relationship between detail and dynamics. Many amplifiers bring detail to the forefront, and they usually have squished dynamics. (yeah, squished is a technical term!) Heavy use of negative feedback softens dynamic contrast, and this allows the details to be presented at similar volume levels to the main harmonics. The effect is to make everything sound super-detailed and wholly unnatural. The SIT presents details, but with proper dynamic contrast. Details do not poke you in the eye, they just naturally unfold as part of the music.

More later.

I guess that is an opinion worth listening to.
