Why do NOS Tubes sound better than new tubes?
They were also allowed to use hazardous materials and work processes that would never be allowed today. 
Capacitor log Mundorf Silver in Oil
For my Infinity RSIIb speakers I needed 2uF and 3uF caps for the low-tweeter and high-tweeter, so I paralleled (2) and (3) 1.0uF Mundorf Supremes. It sounds excellent.

Well I un-watered-down my unit (I guess that would be "concentrating" it). Mine now has all metal foil and metal film resistors, high speed OPA827 opamps, and high quality PP, PS and copper foil/PIO caps. I also moved the power supply and the outp...

Ladycharnet, the EQ box does more than boost below 100Hz. I have studied mine extensively and also modded it extensively, and here are the facts:1) bass gain adjusts bass boost below 100Hz, especially from 50Hz down2) contour adjusts the slope dow... 
Know of any true bullet proof equipment stories?

Preamp Deal of the Century
Power Supply Upgrade Completed!Wow, it's so true that you listen to the power supply - the upgrade sounds excellent. Went from the stock values of 33uF/10H/100uF to 6.8uF/10H/47uF/10H/100uF using Mundorf Supreme/Silver oil and Solen caps and Lunda...

Preamp Deal of the Century
Well, you could always buy a Chenin and gradually upgrade it. I have done tons of work to mine, changing the output tube type, plate loading scheme, output transformers, bias scheme, power supply, etc. Point-to-point wiring makes it a lot easier t... 
Power Cord for PS Audio Power Plant Premier?
I made my own cord for the PPP using Belden 83803 teflon-insulated 12 gauge copper wire, Wattgate connectors and black Techflex braiding. Sounds great to me, an improvement in bass over the stock cord. Best things about making your own are the pri... 
replacing crossover with external one
I did that with my Infinity RSIIb's and it sounds excellent. An external crossover allows you to use much larger (better) components and to space them well apart to prevent crosstalk interference between crossover components and between the crosso...

OK all you Infinity RS 1A/1B Beta speaker owners..
The IIb's are the same way, a point source, just with less EMIMs. The Center EMIM is run twice as loud as the other two above and below it. Here is a link to a thread with posts by a guy who replaced his RS1B EMIMs one pair at a time starting with...

power cord for PS Audio Power Plant Premier
I made my own cord for the PPP from Belden 83803 teflon coated 12 gauge copper wire, wattgate plugs and black techflex. Looks and sounds great! A little on the stiff side, but it can be bent to fit; if you need to get into tight spaces, a Wattgate...

Hey Susieschaeffer,Are you getting the new Graz EMIM diaphragms for your 1B's? They made a big difference in my RSIIb's!
