| Tube question: any sonic difference in 6SN7 vs 6H30 vs 6H80 in the amp's signal position? The 6SN7 is a better sounding tube as its easier to find examples that have lower microphonics. IOW the 6SN7 was designed for audio. BTW the 6C33 power tube has been out of production and the plant that made them dismantled for about 19 years. | |
| Solder, Lead free or leaded? RoHS does not ban leaded solder. To meet RoHS, the product has to not have more than a certain percentage of lead.Leaded solder works better than most non-leaded solders in most applications. A eutectic solder is more desirable as it is much easie... | |

| Atma-Sphere in CO? Just a FWIW- we've had terrible luck with the MIT and Transparent cables; we've never gotten them to play nice with our gear. No idea why, but you might want to run that comparison again if you can borrow a different set of interconnects. Also- th... | |
| highest damping factor amp You don't need a high damping factor to control TAD woofers. My amp has a very low damping factor and works great with the dual TAD 15" woofers (1602s) in my system. Now they are in series for a 16 ohm load, so nearly anything can drive them. And ... | |
| CDs Vs LPs Ticks and pops can be on the surface of the LP, but far more of them are caused by poorly designed phono equalizers that are unstable, resulting in a tick or pop that isn’t actually on the LP. About 95% of ticks and pops have this origin.I am sorr... | |
| New vs Used - Significant sonic improvements in preamp/amp design in the last 20 years? We developed and patented a means of direct-coupling a balanced output. We use it in our tube preamps, the first of which were built in 1989. It was the world's first balanced line preamp for home use.You can still find the older ones used but the... | |
| CDs Vs LPs OK Ralph, you're right. There's no such thing as a not very well built or poorly set up turntable or cartridge, no damaged vinyl, no dirty records, no off center spindle holes, no poorly recorded LPs.Everything in vinyl land is just as good a... | |
| CDs Vs LPs You need to add "to me" or "to vinyl afficianados" to make this statement correct. To anyone with a decent system, digital no longer has to sound bright. The best digital system I've heard to date is the StahlTech, which sounded smoother and mo... | |
| Tube phono stage, or solid state,pre amp A bright high end is typical of solid state. This is due to distortion, not frequency response, despite the fact that the distortion present is very slight (the problem is that the ears are very keen to this type of distortion, as it is higher ord... | |
| CDs Vs LPs No amount of money spend on beefy turntables and complex tonearms will produce the dynamic range of which the LP is incapable.?? Signal to Noise Ratio: LP 50db, CD 90dbFrequency Response: LP 20-20kHz, CD 20-22kHz (a tie)Total Harmonic Distortion: ... | |
| KT88 for deep bass ? The kind of tube has little to do with how it plays bass- all tubes work to DC.The bandwidth of the output transformer, and the way the tube matches to it is a different matter. | |
| Horns: Why don't they image well? Horns tend to give a wall of sound, but rarely can image pinpoint in the horizontal and vertical and depth like the above ones mentioned can.This statement is simply false. It may be true for some earlier horns as the throat design and curvature ... | |
| Why do people buy preamps if they can directly connect amp to stereo source/phone/PC/tv? ^^ In addition to that, a good preamp provides control over the interconnects and in so doing, allows the system to be more neutral. This function seems to be the least understood, but seems to be pretty important, otherwise the system only sounds... | |
| Phono stage w/automatic Load-Impedanance. But which step-up ratio to choose? The least amount of stepup that gives you the gain you need. That will minimize the sonic fingerprint that all SUTs have. Also pay attention to proper loading of the SUT to minimize coloration. Talk to Luhdahl ab... |
