| Power cords and soundstage A properly designed power cord(ie: Teflon dielectric, counter-rotating geometry, etc) will reduce or eliminate intra-conductor interactions that add noise and distortion to audio signals. The right geometry will cancel unwanted magnetic interactio... | |
| system testing discs????? I suppose I should have addressed the question of an SPL meter with regards to the discs. I guess you could use one to analyze you system's lower end response with disc CHE 151's sweep tone(from lower mid to 20 Hz), but keep in mind how terribly i... | |
| system testing discs????? Most of the Chesky discs' tests are conducted using your ears as the only "equipment." Some also contain test signals that are recorded at very high levels, and require an oscilloscope or wave analyzer to be of any actual use. Turn your volume dow... | |
| Leave solid state amps on? Or turn off everytime? Absolutely- Leave them on. | |
| ideal tube for VTL mono 100 amp. monoblock Another thing: If your power amp has user adjustable bias- Check that and confirm that it is within spec. Low bias will result in an un-dynamic, recessed sound from an amp. | |
| ideal tube for VTL mono 100 amp. monoblock Replace the Mullards with either NOS Siemens or Telefunken 12AU7's. British tubes typically have a softer, warmer coloration than German(way more transparent and extended, without any in-your-face glare or stridency). Amperex made some nice tubes ... | |
| speaker recommendations for a 12 x 12 room? Since your room happens to be 12' X 12'(and the reviewer's is also): You may find some useful info in this article: (http://www.avguide.com/products/product-3455/) Read the full review. | |
| Sticking with one brand If you enjoy the transparency that the Kimber line provides- Why change? I've experimented with a number of other companys over the years, but always come back to Kimber(now using their Select line). Their stuff just seems to get out of the way of... | |
| fuses - the $39 ones or the 85 cent ones Well- my guess would be many don't for the same reason the high-end tube gear manufacturers don't install NOS tubes. Too many consumers can be satisfied with newly manufactured Soviet or chinese tubes, and of course- the price of NOS tubes would b... | |
| Audio Research 230/240 volts Actually- Dual-voltage transformers will have four wires, connected to two windings on the primary side. To convert from low to high voltage in, the primary winding connections need to be changed from parallel to series. Few pieces of audio gear c... | |
| How to break in pre-amps ? Your pre-amp absolutely WILL burn-in without your power amp turned on. It does need to be connected to the amp though. Of course- You need an active source(ie: your iPod) | |
| Tubes for Cal Audio Labs Alpha Processor Mr N- I should have mentioned: You'll never appreciate what your Alpha ia capable of unless you try NOS tubes in it. Nothing currently manufactured can come close to the reproduction of the tubes I listed(except perhaps this one: (http://www.music... | |
| Tubes for Cal Audio Labs Alpha Processor I never had any trouble with my Sigma or Alpha being hard on tubes, but I was using 10kHr Telefunken ECC803S tubes. If you enjoy transparency and quiet background; they, or Siemens E83CC's(triple mica, from the 60's) are a very good bet(both very ... | |
| Top resistors Mr D- You are correct! A transparent, non-inductive resistor like the Bulk Foil Vishays(or Caddock Ultra- Precision Film) will make an audible improvement vitually anywhere it's installed in the signal path. | |
| SOS: Ah Njoe Tjoeb Tube CD Player Low-Frequency Di If the sound through the headphones was not distorted: The DAC is(was) fine. I agree with Ed- Call Kevin at Upscale for advice, and possible service. (http://www.upscaleaudio.com/home.asp) It does sound like the problem was in the output section. |
