| RCA to balanced "True, but then you are dealing with the limitations imposed by the transformer"And the limitations of output coupling capacitors have no sonic consequences? Or OP amp buffers? Personally, I much prefer the "limitations" of a quality transformer t... | |
| RCA to balanced ", buy a true balanced phono stage to go with your balanced linestage." Or buy a single ended phono pre with an output transformer like the K&K Audio Maxed Out. Transformer coupling can provide a true "balanced" out. | |
| phono pre suggestions Check out the less costly versions of the K&K Audio Maxed Out the Kevin sells. They can be upgraded to Maxed Out status and will perform very well against everything that has been mentioned. | |
| RCA to balanced The Cardas adapters connect pin 3 (the minus leg of the balanced signal) to pin 1 (ground). This turns the BAL input into a single ended input. No advantage and maybe some adverse effects. | |
| Has anyone listened to the soundsmith Paua cart I bought Peter's prototype Sussurro at RMAF. I mounted it up yesterday and listened all evening. I still have some tweaking to do, but the results so far are very promising. I can post more when it's more dialed in and I've had time to listen to m... | |
| High quality AC turntable motor Bpoletti, turntables that use AC are of the synchronous variety. Their speed is determined by the frequency of the AC, not it's voltage. The way AC line voltage bounces around a motor that depended on it for speed regulation would do a lousy job. ... | |
| High quality AC turntable motor It seems to me that some of the posters here have forgotten some of their Trig. A complete sine wave cycle is 360 degrees. As the previous poster stated one set of field coils is driven by the primary AC current and the other with a AC current 90 ... | |
| High quality AC turntable motor I had a problem a while back with my Nott. seeming to drag some. I lifted off the motor pulley and discovered some hair wrapped around the motor shaft and wedged into the bushing. Removed it and everything was hunky-dory. | |
| High quality AC turntable motor Kevin Carter of K&K Audio has a prototype PS that has two outputs with phase angle adjustment. The only thing holding him back from releasing this as a kit is the need to assemble one so he can write up the instructions. If enough people were ... | |
| High quality AC turntable motor I would consider a PS that has two outputs, one for each field coil of the motor. It should provide the user with the ability to trim the phase angle between the two outputs. The benefits of such an arrangement? The ability to reduce vibrations to... | |
| Mu-metal or amorphous core step up transformer? You might also try posting this on the K&K forum on the Audioasylum site. Kevin Carter the US distributor for Lundahl has great ears and lots of experience with these products. | |
| Electronic stylus force gauge question If the cause is magnetic attraction, once your finger or the cuing lever has released the pick-up arm all the weight will be carried by the scale; no correction needed.If your goal is precision (repeatable results) as opposed to absolute accuracy ... | |
| Electronic stylus force gauge question I am sure that the minus .01g - .03g reading is caused by the magnet in your cart. pulling up on the scale. This could be confirmed by passing a magnet close to the scale to see if the same thing happens. As far as setting your cart. VTF to as clo... | |
| Tonearm Noise Yes, you will hear a noise in your speakers if you tap on your tone arm. It is like a microphone! You cartridge is a transducer and very sensitive to vibrations. It turns mechanical vibrations recorded in the groove into an electrical signal. Even... | |
| schticky to clean lp's It will work as long as you are religious in keeping it clean. If it starts to load up with shit it will deposit some back on to the record. Since the roller moves only in a straight line while the groove is curved this deposition will be intermit... |
