Need Reel to Reel Tape Primer Sources
What is important about tape performance is making sure that the tape head bias during record matches the tape you are using. To set this up usually requires a bit of test equipment.Modern tape absorbs moisture over time which causes them to shed ... 
Why not horns?
Herman, just to be clear here: I don't know the actual impedance of the drivers in the Duo, but in a case where the minimum impedance is 8 ohms, I would expect most amplifiers will have the voltage response to handle that. Its when you go from 19 ... 
What is wrong with negative feedback?
Kirkus, my technique for measuring propagation delay is simple: compare the input to output while using a squarewave source. Observe the difference in time between the rising input waveform and the rising output waveform. That's the delay time. I ... 
What is wrong with negative feedback?
If you can increase the speed of the amp (decrease the propagation delay) theoretically you could speed it up to the point that the odd-ordered enhancement is pushed well outside of the audio band.Our amps are also pretty fast- 600V/usec is a typi... 
Why not horns?
Unsound, Herman and I agree on something :)Herman, The reason the Trios and probably Duos have such an impedance curve has to do with the way the crossover works. Let's use the Duo as an example, but this is only an example, my experience with the... 
Why not horns?
With regards to amplifier power and amplifier types used on horns: My speakers are horn hybrids, using a high efficiency pair of 15" woofers, which limit the efficiency to 98 db. If I push the system hard, I am really challenged to clip a 30-watt ... 
What is wrong with negative feedback?
Loop feedback in any form is supposed to reduce distortion. It is questionable whether it increases bandwidth, and in some models (see the link I provided) it reduces 'output impedance'. You'll see why I use the quotes if you look at the link.The ... 
Why not horns?
Like many other things in audio, its all in the execution. But there is also an 'ignorance is bliss' thing that seems to play out. I've not heard Herman's system so it may well be me who is ignorant. One objection I've always had to generic electr... 
Why not horns?
Herman, your machine is doing 64bit calculations but the DSP signal is only 24 bit, if that. DSPs can be harnessed to a lot of tasks; one thing you learn really quick in dealing with them is they suck the life right out of the music. The master ta... 
Reel to Reel decks
The next is anger, then comes the deal-making, and finally, acceptance :) 
Why not horns?
Macrojack, you had me up until the DSP part. I've spent a lot of time with digital (using both DSP and plain vanilla) and analog recording systems. We use both in our recording studio. While digital falls flat on its face using the master files ag... 
Reel to Reel decks
A few comments. First, tape **Can** sound better than the source. Why? Physical vibration. If you have the speakers playing while making the recording, the tape will *not* sound better than the source, but if you use headphones to monitor and turn... 
Woofers going crazy when playing vinyl
I would check with VPI and see what they think of the effective mass/mechanical resonance issues with regards to playing that cartridge in your arm.The mechanical resonance should be between 7 and 12 Hz, if its off, you can get crazy woofer pumpin... 
Why not horns?
Well I can't be the judge of that- I have no idea what the waveform looks like once its in the air. But compared to a pile of speakers that are supposed to be pretty good at that sort of thing I don't find good horns to be lacking. I find bad horn... 
Listening off grid with batteries
You might also consider setting up a wind turbine to supplement the solar. Most of the people I know that run solar though have come to rely on the panels alone though, as there are no moving parts.As to the system, Getting the most efficient spea...
