I'd better get on with the building of a portable incarnation of this then, the only one in existence at present is sitting atop one of my speakers with wires dangling everywhere, playing out sweet Vivaldi as I type...
Well you're targetting RMAF 13 right so that's giving me a few months to get my act together, not really putting me in a tight spot with that amount of notice. I was building one anyway to document the process, would be happy to have it take part in a shoot-out.
I have 2 DAC's coming in this week. Tomorrow I'll have a Phasure and Thursday a Lavry......
I haven't built one myself but have designed a passive filter which I've simulated and appears to do the job nicely on the ESS Sabre. Also a passive filter at the output of my NOS DAC does more good than harm to my ears. But yes the ultimate test is by listening.
opus111, I spoke with Dan at ModWright on the phone today. I asked him if he passively filters between the DAC and the tube output stage and he said that he does. So I guess there is no need to worry.
For My Ears Only. That's how I see it when it comes to audio. I have been a lover of audio equipment for many years. As a retired African American audio enthusiast on a fixed income I have to be frugal regarding all of my audio purchases. All of my major equipment except my Magnapan speakers, sub-woofers, audio cables, AC receptacles and phono cartridges was purchased used and love what I am hearing.
While I have been a subscriber to Absolute Sound and Stereophile for the past 20 or so years, I generally don't purchase based on their reviews unless I can later hear it and then purchase the piece used. I try to attend as many audio shows as I can and love to hear the mega-thousand-dollar stuff, I can still go home, kick off my shoes, retire to my listening room and engulf myself in my jazz or classical music.
I love reading about individuals who can afford to purchase the high priced stuff. I am sure that most are not influenced by a strong desire to have the best, while denying it may not sound the best. While I understand there are those who buy stuff based on the name, I believe most who truly love the music, will buy their system based on what it sounds like to them. My hats off to those who can afford to buy the very best.

Absolutely true... just because it's bigger and more expensive, does not make it better. I've fallen into that trap and know several others that have as well.
Just because you can, don't mean you should. Things have gotten out of hand with this elitist attitude.
What would be an interesting study is to set up a system, then take frequency response curve of the system, then change ONE thing in the system (cable, pre amp, power amp) that you are testing and then take another frequency response curve of the NEW system and then compare. I wonder if that's an objective method of actually VIEWING any difference in one component vs another to get some objectivity. IF the concept of a cable (power cable, speaker cable, interconnect cable) makes a difference than there SHOULD be a difference in the frequency response curve of the system. At least that's the only measurement that will show SOME degree of differences.
Well, you have more problems doing measurements in the room if for no other reason than ambient noise changing.
However, if we can agree that to change sound in the room you have to change the signal at the speaker terminals then we have something we can work with. Further we could do more than frequency response though that is one thing you can do. Rig up to record with very high fidelity the signal at the speaker terminals. Change something and do the same recording (yes even including the real music) and then do a difference test. Subtract one recording from the other. Whatever is left is the difference.
The old fashioned real-time method is to change something in only one channel of a system, and place a meter between the two hot leads of the speakers. Any difference is what shows up on the meter. Another variant was to run high impedance headphones between the two hot leads, again what you hear is what differs between the two channels. Usually what you would hear is poor channel to channel level matching. There are ways to trim that out if one wished.
Now you could do this with cables and such pretty well. With some changes like two different amps or pre-amps you might have time delays one channel to the other. But it is a method that could be done without all that much difficulty.
NEW? Whoever buys cars new..(same here for audio.) eAnd I also rarely buy new, including my BMWs.
You would need a mono recording to measure channel variations.
Bruce, I've read that you are one of the various studios that is doing remastering for HD Tracks. If that's true, I also checked out that you have a variety of different AD converters and having done some reading, I've read that there is a trend towards studios using DAD converters. Can you post your findings on the mastering of recordings, it would be VERY interesting from the consumer standpoint as to what equipment you used during the mastering process of each recording your studio was responsible for. I've read about what equipment different mastering studios are using from what converters, outboard equipment, playback systems. Many of these studios are using a variety of speakers ranging from Wilson, Eggleston, Duntech, and others, AD converters by DAD, Weiss, Lavry, Prism, etc., cables by Transparent, MIT, etc. and it's always nice to learn from a mastering standpoint as to what's being used and how a mastering engineer does their "magic". A good mastering job can make or break a recording.
It would just be nice to know which recordings your studio did, etc. Thanks!!!
