| Source for Variac J: I would fuse the variac for an amp or two LESS than what its' rated output is just to be safe. If you have a 7 amp variac ( somewhat common size ) and try pulling 10 - 12 amps from it, it can smoke the variac without tripping a 15 amp breaker. ... | |
| Should Class A Amps be left on?? Sayas: Thanks for the follow-up. Hopefully, your posting of honest findings based on first hand experience will encourage others to check things out for themselves. It is good to see that, even though you initially thought your system sounded quit... | |
| What size subwoofer to get? To add to Rives' comments, front loading and downfiring will have DRASTIC effects on bass output and pitch, even if crossed over at or below 65 Hz. I would suggest listening to the two different designs side by side to see which you like best. My ... | |
| Bryston and Conrad Johnson I am very familiar with the various Bryston power ratings, yet was completely unimpressed with their performance at lower impedances on their older series of amps. A reviewer with Stereophile also commented about some current model Bryston mono-bl... | |
| Cable length The points being brought up about speaker cable impedance altering crossover points does not really come into play in the real world. If one were using cables with drastically different electrical characteristics for each individual driver / frequ... | |
| What is a "transmission line" speaker? Steve from HiFi Farm: Owning a couple pairs of Ohm F's, i've never heard these speakers refered to as "transmission lines". Nor does their mode of operation resemble anything close to what is typically considered a "transmission line" speaker as s... | |
| How can an active preamp possibly help? Some digital sources do not output enough signal to drive various amps to full power. As such, one can run into a lack of dynamics. Adding another gain stage takes care of that problem. Sean> | |
| What is a "transmission line" speaker? There are MANY variations on what most people call a "transmission line" nowadays. To try and make things simple, the sound coming out of the back of a woofer is typically loaded into the speaker box. Directly behind the woofer is a chamber that f... | |
| Bryston and Conrad Johnson I would investigate the results of various Bryston amps driving low impedance loads prior to spending any money on the combo that you mention. From my personal experience and those of others that i know and have read about, i don't think that Brys... | |
| Cable length Let's look at this logically. I'll try to do it in plain English so that everyone can follow along.The strength of a signal at line level (interconnects) is very low in voltage and current. Losing ANY of this signal is equivalent to never having i... | |
| Best Dark Sounding Amp For Bright Speakers? Uh-oh... just to clarify things, my comment to "Bob" was aimed at "Rcrump" aka "Bob" regarding the story about the Wilson's that he later filled in. I hope that Bob Bundus did not take this the wrong way. I do agree that some softer sounding Mosfe... | |
| Source for Variac If you do not use any type of electronic gear for an extended period of time, powering up with a variac is never a bad idea. This is especially true if the devices are old and / or exposed to very high voltage levels ( like tubes ). So long as the... | |
| What size subwoofer to get? Stehno hit it on the head. Rives also brings up some important points. One sub IS harder to place than two. On the other hand, two well designed commercially built subs can be quite expensive. Just keep in mind that a vent of any type ( ported, pa... | |
| Test C.D with a signal output of 1VACrms? Since all CD players have various amounts of gain, there is no way to generate a "for sure" level of output on any given recording. While line level standard is 2.0 volts, i've seen some players that are spec'd much lower than this. As such, the o... | |
| Mccormack DNA125, Conrad Johnson MF2250 or AVA Ome Whichever amp you choose to go with should be able to deliver as much power as possible into lower impedances. Dynaudio speaker systems are big-time power suckers and need gobs of power to work best. Sean> |
