Audio Research Ref 250s for Magnepan 20.1s?
Why not borrow a pair of 250s from an ARC dealer and compare them in your current setup. That is the only way to know for sure. The ARC Ref amps are far more neutral. They don't have quite as much tube coloration as Cary amps. The Pass X600.5 are... 
Opinions on ARC VS110/Ref110/VT100mkll/VTmklll
The realistic price of an Audio Research Ref should be somewhere around $5000. This Ref 110 looks far to good to be true. I would not buy something From another country to start. It was probably not set up for the electrical requirements here in ... 
Opinions on ARC VS110/Ref110/VT100mkll/VTmklll
I have owned most of these amps over the years. I have heard the VS 110 but never owned one. I currently own a Ref 110 and I am very happy with it. If you can get a Ref 110 for $2900, you are getting a steal. At $4000. it is still a good deal. Th... 
6550 replacements for upgraded CD7
I discussed this with Leonard a number of years ago when I sent my CD7 in for the upgrade. The upgrade at that time was free if I remember correctly. I was told that the reason for the power supply being upgraded was that there were problems with... 
What Do You Hear When Your Amp Needs Biasing?
You really don't want to wait until you can hear an audible difference. The bias can also drift upward beyond tube tolerances and if left unchecked, lead to a tube failure. It is best to check the tube bias often and make any adjustment that is ne... 
What Do You Hear When Your Amp Needs Biasing?
Tube bias can drift as the tubes age. Especially when the tubes are new. As a rule I like to check the bias every few months. Much more often when the tubes are new. The higher the bias the better the amp can sound to a point. But that will also ... 
Cleaning the equipment
I agree with the compressed air. I would be careful of anything that might cause static electricity. I vacuum the panels of my Martin Logan SL3s every few months. I wrap a cotton rag secured with a rubber band around the tip of my vacuum hose. Th... 
Cleaning the equipment
My stereo is in the front parlor which is separated from the rest of the house by french doors. There are two small air purifiers which run 24/7 on low and get vacuumed weekly. I also cover my components when they are not in use with black towels... 
Buying top brands's older CD players: Pros& Con
You can call ARC and see if they still have transports for the CD1. I know that they no longer have transports for the CD2. But I think you are taking a risk even if they still have a few transports. I would suggest a CD3 or later. The CD3 and la... 
Zoethecus cones
If Skreich is not interested in them I definitely would be. If the amp stand had a Z slab, I would also be interested in purchasing that depending on size. Tom 
Power cable upgrade for ARC
I have found that the preamp power cord makes more of a difference in my system. I own both an LS25 mk2 and Ref 110. Audio Research uses Shunyata power cables at shows and in their demo room. 
First Test for tube bias on ARC Ref 110?
I would check the tubes to see if they have drifted a bit. Then I would check them maybe around a hundred hours. I also own a Ref 110 but I don't use ARC tubes. ARC burns their tubes in a bit before they are matched. This tends to make the match... 
First Test for tube bias on ARC Ref 110?
It really depends a lot on where you got your new tubes and how well they were matched. That said, I test the bias a couple hours after replacing the tubes. Then about every 25 hours for the first 100 hours or so. The tubes will usually drift as ... 
Where to find steel footers?
I really like the stainless steel Dome cones. These cones have a lot of weight to them. I have tried a number of cones or tip toes in the lase 20 years and I like these the best. They come in both large and small sizes. I use the large cones to c... 
MC versus MM. Which to choose.
I am a newbie to vinyl but not to being an audiophile. I have not had a turntable in many years. I am thinking about an ARC PH5 or possibly PH6 for a phono preamp. I have been looking around but used ones go fast. I have not decided on a table or...
