| can I connect 2 sources directly to power amp (one XLR one RCA) @erock79 I don’t mean to hijack the thread, but I wonder if having both XLRs and RCAs plugged in at the same time was somehow affecting the impedance of the source as seen by the amp. In other words they may have been rated very differently, and e... | |
| Washington Post article on MoFi vs. Fremer vs. Esposito I appreciate the link to the Washington Post article which I found to be quite informative and to-the-point after listening to Michael Fremer rant on for 45 minutes about how Mike Exposito wasn’t a professional interviewer, as if having profession... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? If it is louder near the floor, could it be the source of interference is in your downstairs neighbor’s apartment? How many floors in your building? Another thought, it might be worth investing or borrowing test gear that would allow you to posi... | |
| Why do so many people have problems with bass? @engineears Quite the dissertation! Sounds to me like you have knowledge and experience in these matters. I’m just beginning to try to tune my bass. My 15” woofers couldn’t reproduce electronic bass, so I got a small sub. Wrong move: all ‘boom’ an... | |
| Less Is Really More - Schiit's New Yggdrasil DAC - Less Is More @shooter41 10-4. I’m happy with my upgrade from the Yggdrasil GS (Garage Sale) which included the newer analog cards as well as the LiM chip. It surprised me that all this DAC controversy focused on a single 8-pin chip while the analog boards took... | |
| New Dedicated Line - Almost No improvement Wow! I can certainly understand why you’re disappointed. One solution would be a system (conditioner/uninterrupted power supply) which employs a battery such that the AC for your system is generated from the battery’s DC power. Another item you mi... | |
| how much should I spend to get a better turntable than my current turntable? @grislybutter Sorry you had a bad experience with the Music Fidelity MMF 2.2, I am having a good experience with a used MMF 5.3. However, I purchased from an online retailer that set it up properly. You may want to make a trip to a dealer or find ... | |
| Go get out your pitchforks, I’ve done a sacrilegious thing. . . I have an original Loki, and I find it useful in my main system as a tone control, mostly for rolling off the highs that hurt my ears on certain recordings, but also for ‘taming’ voices (usually male) that grate a bit, and finally to boost, or que... | |
| What's better, one conductor or two conductors for an RCA interconnect? I’ll second what @kijanki wrote. I have never encountered RCA connectors used with coaxial cables. I would expect coaxial cables to use BNC connectors, as I think someone else mentioned. The higher end cables, such as those that came from the fact... | |
| Using Adcom GFA-555s as monoblocks to power magnepan 3.3s in active biamp @allenf1963 You’re asking questions about a topic on which I’m a bit fuzzy. I studied the design of filters for ‘high pass,’ and ‘low pass,’ performed the basic calculations, and became conversant in ‘first order,’ ‘second order’ and the like; ‘no... | |
| Internet Radio on Audiophile Quality 2 Channel System @boxcarman I discovered that my Auralic app (Lightning DS) which came with my player, that is, a free download (my player is an original Aries) can trick my DAC (a Schiit Yggdrasil) into upsampling the MP3 (x4), to the point that it sounds better ... | |
| Using Adcom GFA-555s as monoblocks to power magnepan 3.3s in active biamp @allenf1963 I forgot the math. Since P = I * V, and since V = I * R, then P = l * (I * R). When you turn the flash light on, and the bulb heats up, it’s resistance increases, and you find the source voltage across the lamp (don’t try this with an ... | |
| Using Adcom GFA-555s as monoblocks to power magnepan 3.3s in active biamp @allenf1963 If I may comment on @petaluman ’s answer, in terms of Ohm’s Law, let us say you have an old-time filament-type flash light. If you Ohm out the bulb, it shows continuity, just as a speaker coil does, but when you turn your old-time flas... | |
| Using Adcom GFA-555s as monoblocks to power magnepan 3.3s in active biamp @allenf1963 I tried responding to you earlier today, but lost my carefully typed reply disappeared when I tried to exit “preview.” I shall attempt a recreation. Most of the discussion on the ‘Electrical Side,’ as you put it, revolves around Ohms L... | |
| What cause tweeters hiss ? @auronthas Interesting article, thank you for posting. I agree with you about the cable, it served a useful life. Not sure what to recommend to replace it, different cables have different sounds and some equipment works better with some than with ... |
