| Buy High Pass Filter or KAB RF1? Chakster, On a purist basis, I would question the use of those AT pneumatic isolators under a loudspeaker, because it seems to me that depending upon weight of speaker and stiffness of the AT feet, the speakers might be free to rock back and forth... | |
| Help!! Bought Rega TT in the UK and now cant use it in the U.S. You might at least check to see if what Chakster said is correct. Is there in fact a 50Hz/60Hz switch on the motor? (I'd be surprised.) If not, I would think your cheapest option is to spend the $150 for the correct motor. If you return your pre... | |
| Unsolvable Woofer Pumping (Phono only) Since the advent of small, high power, Class D solid state amplifiers and the rise in popularity of home theater, about 20 or more years ago, there have appeared in the market a myriad of small, self-powered subwoofers that typically also have adj... | |
| Buy High Pass Filter or KAB RF1? Craigert, Re this last post, define "rumbling". Are you hearing a noise or are you watching the drivers do a dance, in and out? | |
| Unsolvable Woofer Pumping (Phono only) newbee, Good point. But the cure of damping might worsen the disease. Damping would add mass to the tonearm, and that would drive the resonant frequency downward. Resonant frequency is inversely proportional to effective mass. Oil damping, as ... | |
| Unsolvable Woofer Pumping (Phono only) No. A speaker with extended bass response would not help. Most cabinets are ported in one way or another and therefore don’t exert much control over the woofer motion. However such designs in my opinion offer a natural sounding bass response. What... | |
| Unsolvable Woofer Pumping (Phono only) If you do eventually install a high pass (rumble) filter, you might choose a lower frequency roll-off. 10Hz should do it. If your filter has its "knee" at 20Hz, that will affect higher bass frequencies more than is necessary for the effect you des... | |
| VTA Cartridge To begin with, based on his description (see above), I think the OP is conflating azimuth with VTA:"Could I consider that the front face of my cartidge (DV20x2H) is perpendicular (90 degree) relative to the vinyle surface, can we concider that it ... | |
| Buy High Pass Filter or KAB RF1? Craigert, Based on one of your posts here, do you seriously plan to put the filter between the phono cables and the phono input of your preamplifier? If so, that's a no-no, if you care at all about SQ. If you're bi-amplifying the speakers, do y... | |
| Tubes sound like a broken lightbulb Depends upon how hard you shook them to elicit the sound you hear. Don't forget those octal triodes have a large glass envelope with substantial metal and mica structures inside. I do believe that if you shake such tubes GENTLY, you might hear t... | |
| Denon Turntable DP 15F runs backwards ! Someone suggested cleaning the tape coating the inner rim of the platter with alcohol. I am not sure this is a bad idea, but it might be. The guiding principle is that that tape coating is essential to proper function of the speed control system.... | |
| Recently Inherited a Kenwood L-O7D If an L07D falls from the sky, it will likely fragment unless very well secured. | |
| SPL Phonos Phono Preamp audiofun, It is I who owe you an apology for being a bit snotty in my initial post. We can agree to disagree on whether or not AC from the wall socket carries the "entire electrical signal", but I do disagree with you. You use the word "signal";... | |
| Recently Inherited a Kenwood L-O7D The outboard power supply should have a long umbilical cord attached to it. At the other end is a complex plug that should mate to a male receptacle on the main chassis. FIRST, before you do anything, see if it is a 100V version, which in all li... | |
| Which vintage direct drive? Terry, You compared your top of the line Nottingham to an old technology, and chronologically old Technics DD. That is really not a fair comparison of belt-drive vs direct-drive types. The Dias would be far superior to the Technics, in so many w... |
