| ARC Ref 3 Main Output Impedance Question Normally if you have a balanced circuit, 20K should be no problem. Balanced circuits **should** be able to drive 600 ohms- so 20K should be like a walk in the park. But many high end audio products don't support the balanced standard, and ARC is o... | |
| An analog question for those who record Davidnboone, if you are doing cassette you will have to find a machine and get it refurbished. Pioneer made some very interesting high-end machines that used Dolby S about 20 years ago- very nice sound, very quiet. Otherwise a Nakamichi is the thi... | |
| Anyone read TAS's Ten Most Significant Amps? Isn't the H/K Citation 2 on that list? I would not regard that as an old-timer's issue- that amplifier *is* pretty significant- it has wide bandwidth, low distortion and decent power (for the day), and if properly refurbished keeps up with modern ... | |
| What does one purchase after owning horns? Chadeffect, it does appear the newer Trio has a higher impedance. Their website does not have a lot of technical data, but it seems pretty sure that 3 of the 4 passive crossover components must be caps. If a choke is added to the bass horn, the ov... | |
| What does one purchase after owning horns? T_bone, In the case of Avantgardes, all you have to do is look at what sort of amplifier the designer is using (that is the case with most speakers). He uses a low power transistor amplifier, which explains the 'crossover' of the Trio (its all cap... | |
| What does one purchase after owning horns? Mrdecibel, I suppose this all could be boiled down to damping characteristics. How you would have to view it is like this: 1) some speakers like lots of damping and others don't.2) Some amps have lots of damping and others don't.3) Don't mix the t... | |
| What does one purchase after owning horns? I have dropped this link many times:[ur]http://www.atma-sphere.com/papers/paradigm_paper2.html[/url]It has to do with two different design, test and measurement techniques, both of which are alive and well in high end audio. Weseixas subscribes to... | |
| Phono Preamp-Nothing you like so Build your own? Heyraz, if you are doing DIY I think you will find you can do a lot better than designing around an opamp. Have you looked at http://www.diyaudio.com?Food for thought: if you set up a zero feedback circuit, even though it has the same bandwidth as... | |
| OTL Tube Amp for Maggie 3.6? There are two ways to make an OTL work with 4 ohms really efficiently.The first is to make it so big that 4 ohms is no worries (our MA-2 and MA-3 are examples of that- the MA-2 makes its maximum power into 5 ohms and the MA-3 makes its maximum pow... | |
| Can I swap a Stepped Attenuator for a Potentiomer? Switches make a difference in performance. The reason is that not all contacts are created equal- the best will be doubled up to increase contact pressure and area. So yes, the input switches can make a difference.If you are really considering doi... | |
| Best tube mono blocks under $15,000? Just FWIW, based on the impedance curve I have seen of this speaker, the MA-1 should do just fine on it- although it may be a good idea to use a zobel network centered at about 1 KHz.Alternatively a set of ZEROs could be employed. | |
| Best phono stage balanced under $3000 used Manitunc, the advantage of running the cartridge balanced is the fact that the balanced cable will have no effect on the sound.The balanced system was in fact devised to eliminate cable artifacts. In doing so cable length is less important as is t... | |
| How important is the tonearm? One nice thing about the Triplanar is you can set up the effective mass of the arm/cartridge system to match a range of cartridge compliances. Beyond the abilities to set the usual adjustments, this feature reduces the need to be picky about the c... | |
