audio research sells out good or bad ?
I would expect more HT from the new ARC now. While I do note the case studies of past buyouts I doubt things will be as doom and gloom as many have posted. Either way it will be fun to watch. 
Thiel 3.6, what will drive them best?

Experience with the NAD M5.......
How does this unit sound?my experience with it left me cold. I felt it was boring too smooth on top and therefore too predictable. Used it with NAD M3, and then an ARC VT100MKII into my dyn speakers. It made horrid sounding cd's more listenable bu...

AR LS 26 and Pass Labs X350.5 Compatible?
Bob, that x10 multiplier "rule" is not something I put much faith in. To actually calculate the drop in dB for this kind of case you simply apply the voltage divider principle at a specific frequency. For example if at 20 Hz the output impedance (... 
AR LS 26 and Pass Labs X350.5 Compatible?
Bob,I am somewhat troubled by those findings as well, but when you realize the output capacitance it has to be that way. But it seems odd that ~18k for a sota preamp... this should not be the case. To get the most potential from your system specs ... 
AR LS 26 and Pass Labs X350.5 Compatible?
I forgot to mention that I have an X250.5 (same input circuits/same drive impedance give or take as the X350.5).For the record, let me state that these single data points are pretty useless. They are mostly marketing figures. Think about it folks.... 
AR LS 26 and Pass Labs X350.5 Compatible?
The thing that would be nice to know, to give a better feel for this whole impedance gig, is output impedance vs frequency. All too often manufacturer's supply a single figure for output impedance for say, a tube preamp. It's usually at 1 kHz,and ... 
Tube sound with no tubes
11k single ended, 22k balanced (what I used)You are right though, it does demand a low enough output impedance across the audio band for no roll-offs. 
Tube sound with no tubes
Spaz,1st, I love the moniker. That is how I feel about my usual approach to equipment "upgrades" and auditions. I too have a Pass Labs amp, the X250.5. I recently sold a BAT Vk5i preamp, used it with a Cary SLP 05, and for a long time an ARC LS15.... 
What does Jitter sound like?
Shadorne, I know what you mean. There is a point after which it really is just a silly excess. I've had just as much emotional involvement with my music through the years of upgrades, as I do with my car system. ALl the upgrades have never changed... 
What does Jitter sound like?
Dgarretson: great example of a controlled experiment. I wonder how much the improved clock circuitry reduced radiated emmisions, reduced injected noise into the ground planes, vs the degree it reduced actual clock jitter. I'll always have a hard t... 
What does Jitter sound like?
-Impossible to quantify unless you can tweak the actual jitter specs in the same DAC/cdp. -If a designer has taken the road less travelled in reducing jitter to minimal levels other areas of the DAC/CDP (power supply, filtering, analog section, is...

Are passive preamps better?
Pubul57,I have used three different tube preamps with my Pass X250.5: ARC LS15, Cary SLP-05, BAT Vk5i. I have used these with my two digital sources, Marantz SA11S1, and a Squeezebox 3 (with overkill linear PS). I have also used a TVC for a few mo...
