| Pure Class A SS vs Tube Amp The hiss levels produced by some amps which may be perfectly fine with say 90 db speakers could very well be bothersome with 102 db speakers.@almarg That's usually more of a preamp thing. Most amps are plenty quiet to be fine on a speaker of 102d... | |
| Seriously considering tube preamp…opinions? and I was wondering if there are tube pre's that are more suited to SS amp matching in terms of impedance matching. Do I just go by the 1/10 rule (output impedance for the pre)? Al's comment is correct- look at the 20Hz output impedance if you ... | |
| Pure Class A SS vs Tube Amp I read somewhere that tube don’t have dynamics for movies thanks and I appreciate through KLF 30 fan @lordrootman What you read was misleading. Dynamics should come from the signal, not the amp. As long as the dynamic range is within the power c... | |
| Seriously considering tube preamp…opinions? @hilde45 The thing you have going for you with the Salk speakers is they have a moderate 8 ohm impedance with no nasty phase angles or dips. This makes the job of the amplifier easier. Jim is pretty conservative about his ratings- I suspect what ... | |
| Seriously considering tube preamp…opinions? but I'm completely in the dark about what your stuff costs.We make a 6SN7-based preamp that as a line stage is $1900.00.@hilde45The line stage of my prior comment above is the UV-1. Were you planning to run a balanced preamp or single-ended (the ... | |
| Seriously considering tube preamp…opinions? One parameter is budget. Is this Atma or Ear in the neighborhood of $3k?@hilde45 We make a 6SN7-based preamp that as a line stage is $1900.00. It is single-ended. We also make balanced preamps (and were the first to do so) but they retail for mor... | |
| Classic Audio T1 and T3 field coil loudspeakers From https://www.avshowrooms.com/florida-audio-expo-2020-awards-show-report.htmlClassic Audio, Purist Audio Design: John Wolff gives us a room walk-around naming the components including the Classic Audio T3 loudspeakers. Also, something new fro... | |
| Atma-Sphere MP1 with single-ended inputs and outputs? Adapters OK? @luisma31 Tie the shield at both ends, or only at one end. If only at one end traditionally that would be at the preamp end, but you'll find its not of much concern. What is important though is that pins 1 and 3 are tied together, and that connec... | |
| Class D amplifiers have very little phase shift but that is horse chasing after barn doors are open, and there is always a better way.Sorry, I can't make out what you're trying to say here. | |
| Class D amplifiers have very little phase shift In a self oscillating class D amp, the feedback itself is used to correct phase shift. Its pretty effective in this regard.But I've been listening to a class D amp with zero feedback, switching at a fairly low frequency (400KHz), with a rather con... | |
| Low-sensitivity speakers — What's special about them? What it comes down to is... really good mids with any type of top end extension without cone break up is hard to find in true high sensitivity speakers.The Classic Audio Loudspeakers use a beryllium diaphragm with Kapton surround in their compre... | |
| Best Value Line Stage Tube Preamps? Given that very helpful clarification, what would be your optimal components for a balanced line electronic chain (source - preamp - amp)?Optimal? The sky is the limit... I prefer analog, and since all cartridges are balanced sources, I would pro... | |
| How to guarantee to lower noise- ground loops in your system What many people don’t realize no matter how good your equipment design is if you are feeding ground off the same circuits you can pickup noise @audioman58 This actually isn't universally true. Its only true if the audio equipment puts current th... | |
| Looking for a plenum-rated balanced cable that won't require a second mortgage https://www.redco.com/Carol-E2102S-Plenum-Rated-Balanced-Install-Cable.htmlMake sure your gear supports the balanced standard, else this **might** sound pretty dreadful. | |
| comparing two pre-amp/phono section buying scenarios, so weigh in! If I were to stay with the CJ line section I'd simply have the CJ phono section installed. An internal phono section doesn't have connectivity problems (if you've ever heard how an interconnect cable can change the sound then you know what I'm tal... |
