| Power cable dilemma @jrimer Again, where is the data that shows power cord technology has taken a quantum leap in the last 5 years? How can I put this delicately (and I mean no offense)? Are you new to the audio scene? There's an immense amount of information ou... | |
| POP sound when turning off TT Please let us know if it solves your problem. | |
| Power cable dilemma @pennfootball71 If you look over the posts, the "high end" cable was revealed. It’s a $40 Pangea cord. | |
| POP sound when turning off TT @bound4h Would this work? I don’t know, but it probably doesn’t have the filtering that the Isobar Ultra has. The Line Conditioner is probably overkill for what you’re experiencing, and since it has a rather large transformer in it, you may b... | |
| Amp preamp impedance matching...can anyone explain? Back in the days of tube audio gear in radio stations, almost everything was 600 ohm transformer coupled (inputs and outputs). Some professional broadcast solid state gear was even transformer coupled (not sure why, except for maybe RFI rejection)... | |
| Amp preamp impedance matching...can anyone explain? @mulveling OK, that sounds good to me. Maybe you can explain (in better terms) the need for the 600 ohm terminating resistors with older transformer 600 ohm output gear? Many tube preamps will require a minimum load of 10K or higher, which can... | |
| Amp preamp impedance matching...can anyone explain? @mulveling it specifies a recommended load impedance of greater than 300 ohms I totally understand the concept of solid state low impedance op amp output feeding a solid state op amp high impedance input. No questions there, but these transfo... | |
| Amp preamp impedance matching...can anyone explain? @mulveling @river251 The Ren V claims an even 150 ohms or less over the entire music bandwidth That looks to be true, but if you look at the pre-amp specs, the Ren V wants to see a recommended output load of 300 ohms. Most solid state pre-am... | |
| POP sound when turning off TT @bound4h It sounds like to me that the Rega Planar 6 has a linear power supply (with a transformer), and when it is switched off, it’s emitting a spike into the power line, which is being picked up by CAX81. The Schitt Mani may have used a switc... | |
| Power cable dilemma @jrimer It would be interesting to see what the results would be if you switched the sequence of cables around next time in another study of your perception of amp temperature and performance, ie, starting out next time (with a cold amp) with th... | |
| Soundstage drastically worsened when I replaced a solid state AV amp with tubes. It is as though I am back in the 1950s listening to a single mono speaker directly in front of my listening position. Are you 100% sure the mode switch on the MC275 is set to stereo and not mono? | |
| Soundstage drastically worsened when I replaced a solid state AV amp with tubes. The components are behind the wall in the photo What photo? | |
| Soundstage drastically worsened when I replaced a solid state AV amp with tubes. does anyone have any ideas regarding why the soundstage so drastically changed? Simple; you’re now using a totally different amplifier design (tubes). Welcome to the world of audio equipment. The amp, if brand new, may require a burn-in period.... | |
| Crimping tool? If you know how to solder (any audio enthusiast should really learn, if they don't already know how): 1) strip the wire to be attached to the connector 2) with a Needle Nose Pliers; delicately crimp the wire to the connector 3) for extra added ... | |
| Maximum Input Voltage Anyone know what the “maximum input level” in Volts RMS for the balanced inputs? It looks like the Adcom’s GFP-750 manual does not state this information, so I’m not sure how anyone would know it. Here’s a good rule of thumb; most balanced anal... |
