New KT150 tubes?
Wolfy ... you kill me. :) 
Tube Amp for Martin Logan Speakers
Well stated Mapman! :) I think the EPDR link I provided supports Ralph's comments that low impedance speakers may have an even lower EPDR rating than what is nominally reported or measured. Even more important is that speakers presenting low EPDR ... 
Tube Amp for Martin Logan Speakers
Folks, some may find the Stereophile article about "EPDR" quite interesting at this link: http://www.stereophile.com/reference/707heavy/index.htmlI think one important take-a-way is that speaker impedance ratings, by themselves, do not take into a... 
New KT150 tubes?
Wolf.... please, let's keep it clean. Naked tubes ... really! 
Tube Amp for Martin Logan Speakers
Unsound, you state above "that [if] one can get greater sound pressure into a 4 Ohm load with a ss amp, then we can use that extrapolation to suggest that as frequency response is measured in dBs, one can extend bass response and therefore extend ... 
ARC Ref CD-8 compared to CD-6 and/or Ref CD-9
Your comments make sense Jake. As I said, the CD-7 is a fine player. You might be able to pick up a preowned CD-8 for not too much money with a flip of the CD-7. I happen to like the CD-8 over the CD-7. But that's my opinion. 
Tube Amp for Martin Logan Speakers
Ralph, as I have come to better appreciate, there are very few if any perfect solutions to audio technical issues. It seems that EE/designer folks like yourself make judgments and compromises to achieve a certain balanced product that has market v... 
Best cartridge for VPI Scoutmaster Signature
Add Lyra Delos and Kleos to the list. I mounted a Lyra Kleos on my tricked-out VPI Classic (reg 1/2 plinth and Classic 3 tonearm). Phenominal performing combo. Soundsmith VPI Zephyr is my backup. Works very well with the Classic, but nowhere as go... 
Tube Amp for Martin Logan Speakers
Ralph, George and Mapman .... I have no dog in this fight, but I have read the several posts and would like to suggest that much of what everyone has written has merit. Let me suggest to my fellow hobbyists that you aren't really disagreeing with ... 
ARC Ref CD-8 compared to CD-6 and/or Ref CD-9
As I said, I used to own the CD-7. Compared to the CD-8, I found the CD-7's sonic presentation to be a touch dark; almost thick. IMO, I think imaging is a bit better with the CD-8. Also, better dynamics, drum hits and so forth. The two main differ... 
The sound of my new electrical service: Day 1
Harv ... since you mentioned it, how fresh are your tubes?? Maybe time for a new set??? 
The sound of my new electrical service: Day 1
I gotta believe .. or maybe hope ... that the new AC utility transformer is breaking in. What else could it be? JimMc ... if you pick this thread up, what are your thoughts?? 
New KT150 tubes?
Wolf, are you mixing and matching thoughts. I think Tsushima's comment refers to life testing the KT-150, not so much the sound. Just my own lay reaction is that from what I've read, the KT-150 doesn't draw a heck of a lot more current than the KT... 
Tube Amp for Martin Logan Speakers
Ralph, ... if a speaker has a rock and roll impedance curve that varies from 4 ohms to 20 ohms as a function of FR, would using a ZERO to double the impedance, say ranging from 8 ohms to 40 ohms, cause a Voltage Paradigm amp (i.e., a SS amp or low... 
Tube amp power watts equivalent to Solid State?
Bob, I look at the relationship between amp type and speakers this way. I suspect we are probably saying the same thing, but just a little differently. For example, asssume a speaker was voiced/designed to be driven by an amp having a very low out...
