| UHA Reel to Reel/Tape Project opinions Mikelavigne has got it spot-on- digital still has a long way to go before it will beat out the best of analog tape! If you spend some time in a recording studio using high quality microphone feeds (in my case, refurbished Neumann U-67s driving ref... | |
| XLR waste of time ? Nrenter, you got it exactly right. That is why I am careful to stress 'properly set up' and 'low impedance' as those things are critical to getting the performance out of cables in general and balanced lines in particular.Preamps with RCAs tend to... | |
| Double down, good or bad? Unsound, I've heard a set of our MA-1s driving the old Full Ranges, which were one ohm (we used a set of autoformers that had one ohm taps). There is an old TAS review which mentions that from the early 90s as the speakers were owned by a TAS reve... | |
| XLR waste of time ? Jimjoyce25 All the subtle design parameters, like cable geometry, purity of materials, conductors spacing, the use of platings in connectors and the like vanish as variables when you use the low impedance balanced line system.In high impedance sin... | |
| Double down, good or bad? Unsound, we got a Golden Ear Award for our MA-1 driving a set of Apogees. This is a zero-feedback tube amp BTW.Kirkus, its clear to me that your perspective is that of the Voltage Paradigm. As to papers on the subject, one was written by one of th... | |
| Double down, good or bad? Kirkus, you are right in most of your posts and apparently either did not read something somewhere in mine or misinterpreted it. First, I'm not talking about clipping here- at all. I am well aware of the significance of the woofer in the box! The ... | |
| XLR waste of time ? Jimjoyce25, the standard Neutrik will do the job. Its available in both silver and gold versions. There are of course exotic XLR connector varieties, but IMO/IME, if the balanced line is set up correctly, they don't make any significant difference... | |
| Phono stage for tube system - recommendations? Jmcgrogan2, if what you say is true, then Lloyd has not spent a lot of time working with tubes! The 'unbalance' issue is literally a red herring. | |
| XLR waste of time ? Nrenter, Its a fact that there are cable guys out there that have no idea how to execute balanced cables, especially ones for phono!Most arms that have a 5-pin connection are perfect balanced sources, as the wires are shielded by the arm tube itse... | |
| Double down, good or bad? Magfan, voltage source / current source are Voltage Paradigm terms. A Current Source amplifier is one with a high output impedance. The Power paradigm term for this is 'power amplifier' since such amplifiers attempt to make constant power into all... | |
| Balanced tube preamps w/ remote to consider? FWIW any older Atma-Sphere MP-1 can be optioned with the remote. | |
| Double down, good or bad? Al, in the case of the B&W 802 you need to have 3 db more power into the 4 ohm woofer load as you do into the mids and highs because the woofers are 3 db less efficient. I am ignoring the effects of feedback here and doubtless there are amps t... | |
| which is better ? MC phono stage or MM+step-up ? Yes, SUTs are susceptible to hum. If running direct- there are big differences in high gain phono sections too, so comparison is anything but a level playing field! | |
| XLR waste of time ? XLRs are often better than the best of RCA ICs, no worries there. Plus- all cartridges these days are balanced sources. The advantage of a balanced input on the phono preamp is that you can set up the phono system and run the signal balanced.If yo... | |
| What is your favorite tube for a preamplifier ? 6SN7s are nice as they have a low microphonic aspect. They are great in line stages and can handle a lot of current so wide bandwidth is easy. Although they have less gain than 6DJ8/6922s or 6H30s, the reduced microphonics compared to those tubes ... |
