Warm and Detailed S.S. Amp?

Moscode 401HR...a tube/SS hybrid...can be warm and detailed with the right input tubes. It can also be very neutral. Tube rolling is a benefit of it's design, and they can be easily changed by flipping down the faceplate.

The Modwright preamp can be warmed up with Sylvania GB-5687 tubes and/or certain NOS 5AR4 rectifier tubes.

Upper bass, lower mid, upper mid, lower treble...

Sometimes, I wonder if we're all discussing the same frequencies when we write about these things.

Specifically what frequency ranges define these terms?

My question is genuine. I don't believe we can have a discussion about upper bass, lower mid, etc if we all are talking about different frequency ranges (or even worse, if we don't know what frequency ranges are involved, which is a scenario more common then we might like to admit).

Robert Harley, in " The Complete Guide to High End Audio" defines them thusly:
16Hz-40Hz Deep Bass
40Hz-100Hz Midbass
100Hz-250Hz Upper Bass
250Hz-500Hz Lower Midrange
500Hz-1000Hz Middle Midrange
1000Hz-2000Hz Upper Midrange
2000Hz-3500Hz Lower Treble
3500Hz-6000Hz Middle Treble
6000Hz-10,000Hz Upper Treble
10,000Hz-20,000Hz Top Octave

Maybe in addition to Harleys breakdown, we also need one of those charts that show the range of all of the musical instruments etc so when I describe low bass coming from a flute you can look at the chart and tell me I'm FOS because a flute don't go that low!

I have an outstanding chart like the one you describe. It's in an Audio Control C-101 manual. After I sold my C-101, I recalled the chart was in the manual, so I wrote Audio Control and asked if they had any old manuals left. They did, and they sent me one. That company is excellent...and some of the best, most user friendly manuals ever written, IMO.

Good stuff, Nsgarch. Thank you.

I thought Bedini made pasta sauce?

Marco, what SS amp replaced your Panache? I know you were a Panache enthusiast, so whatever you have now must be quite good.

Marco, I owned Odyssey Strato Extreme Monos for a short while, and I agree with all the points you raised. They were, in fact, warm sounding and mine also had highs that were a touch harsh, which ultimately led to their sale. I used them with a Lamm LL2 Deluxe preamp.

Do you have the Stratos dual mono, or the Kartago (I don't know if the Kartago is dual mono)?
