Soundsmith Carmen vs. Dynavector 20x2H
I have the DV20X2 H and the Sounsdsmith VPI Zephyr. The Zephyr, whi9ch lists for $1K,is a notch or two above the Carmen. I highly receommend the Zephyr. I've been through a number of carties and the Zephyr, at its price point, outclasses most. Btw... 
Cables more hype than value?
Anyone in the mood to kill again the old topics of why generous amounts of negative feedback and high damping factors are good . . . or bad? 
Offset Angle on VPI Classic Tonearm
Stereo5, I have a similar set up: VPI Classic 1, with a Classic 3 wand, and Zephyr carty. Great combination. I have a DV 20X2 H as a backup. It's a back up because the Zephyr sounds better . . . to me. I've also tried the Clearaudio Virtuoso and M... 
Electronics 101: Use of Negative Feedback; a Q
Marakanetz, based on what littleI do get, I think Kirkus is spot on. I doubt the outcome would be diffent though. I think both would advise that in order to make the best decision, you gotta listen to the gear. However, as others have also written... 
Bass leaves after amp warms up?
I've been following this OP with fascination. I'm going to record my stereo too. ;>') Kidding. Bottom line: should Fishing simply turn the volume up to get to the sweet spot?? If so, 300+ posts later, it sounds like a pretty simple solution. I ... 
Electronics 101: Use of Negative Feedback; a Q
Fascinating!I've copied an excerpt from Mr. Atkinson's review of the Ref 150:"As expected, the Ref 150's output impedance varied according to the transformer tap selected. The 16 ohm tap measured 1.4 ohms at low and middle frequencies, rising to 1... 
Electronics 101: Use of Negative Feedback; a Q
Thanks again Kirkus. Admittedly, I am not familiar with Atkinson's test involving an IHF speaker load. Care to explain what that test is all about?So, going back to the use of NF to reduce an amp's output impedance, in the case of the ARC Ref 150 ... 
Electronics 101: Use of Negative Feedback; a Q
Quick follow-up to my last post. As I recall, some time back, one or more of our EE audio tech members commented that a DF of more than 20 DF doesn't add much acoustic benefit. I think a DF of 20 correlates to an output impedance of .4 ohms. In la... 
Electronics 101: Use of Negative Feedback; a Q
Thank you Kirkus for your cogent and thoughtful response. Hopefully, we will read more posts that address the very narrow issue about using NF to compensate for "varying impedance-vs-frequency characteristic[s]" of speakers. You also said that "[i... 
Any bad experience with wilson audio sasha w/p?
Ricred1, I agree with your last point about leveraging off dealer expertise. However, I would caution that I have found some dealers to be somewhat limited in their ability to advise on set-up, including equipment compatibility. Of course, I'm sur...

There's a thread running about cryo'ing gear. I think cryo'ing the wife will reduce distracting ambient noise levels. ;>') LOL. I have the same problem. My wifey threatens to throw a bucket of water on my rig all the time. Good luck. 
Audio Research SP-3A-1 part
Consider cryo-treating wifey. I posted the same suggestion on another OP that asks for thoughts on cryo-treating gear. Tremendous improvement in lowering ambient noise when listening to the rig. LOL ;>') 
Audio Research Corp Ref 5 SE
Hearing some more changes. The soundstage seems to have moved back and it's now about 2 feet behind the speakers. The speakers have largely disappeared. The center stage is filling in with more detail. Imaging is improving. Mid-range and treble sm... 
Current - Class A vs Class A/B, various wattages
Mesaboogie: Call the factory and ask what type of amp they recommend. I would also ask the factory a reality check Q about the type of amp the designers had in mind when they voiced the speaker. I would also search the web to see if Stereophile or... 
Bass leaves after amp warms up?
Hah. Problem solved!! I was right. Mr. Fishing.. confirmed it -- ghosts. Your system needs an exorcism. I'm running a 2 for 1 special this week. Send me an e mail and we'll discuss the pricing. So is Amityville on Long Island?
