| Question About Audio Research Preamp Specs You're reading it right and your 10 to 15 x is generally accepted. The world will not stop rotating if you use a 10k load.I think where this goes is that the preamp may not meet full specs if you feed it into a 10k load. Output voltage may be comp... | |
| electrical isolation of amp and other gear I'm with Steakster. Keep an open mind.Shielded AC cables can pick up a lot of hash on the shielding and introduce that to the component chassis. If you're running single ended components where signal ground and chassis ground are tied together thi... | |
| heeeelp please audio reserch 5SE - resistor blew up Unless the amp is noisy give the tubes some time to break in. If it's noisy then you probably got a bad tube. Also if you hear something through the speakers when tapping on the preamp chassis you've got a microphonic tube. It happens no matter wh... | |
| Tube amp buzz (amp, not speakers) AC quality is usually brought up and probably for good reason. Some transformers can tolerate it and some buzz. It would be worse at certain times of the day than others.Wouldn't hurt though to check the transformer screws and mounting.Some transf... | |
| Impedance match For audio impedance matching really comes into play for transformer coupled stages like tube amplifier outputs or phono inputs.Other than that 10X the source impedance is the general rule although some manufacturers may recommend higher. | |
| Laserdiscs- how do they sound with outboard DACs I thought they carried 16/44 2 channel audio along with analog tracks and the later ones Dolby. I would definitely think it would work.Actually sounds like fun. I haven't seen a working player in years but I remember the disc packaging on some set... | |
| ST 70 best sounding version? I'm partial to Bob Latino's version but the only other one I've heard is the original and I'm going from memory there.I have built a pair of Mark IIIs from the Triode Electronics kit and the power supply upgrades are nice but the chassis is more u... | |
| Highest BUILD quality tube amps? From my experience -Audio Research line stages will generally run for close to 20 years after which the power supply caps may reduce reliability. (LS25Mk1 Ref2Mk1 LS26)The power amps require some bravery though. (VT100Mk1 Ref110) However both are ... | |
| Audio Research VS115 and VT100 Questions ? In answer to the plug question. The amp end is 20 amp but the wall end is a regular 3 prong plug.I replaced my VT100 with a used Ref110. An option to consider... | |
| DEDICATED CD PLAYER $1K AND UNDER, THOUGHTS? I also agree that keeping the same CD player and adding a DAC makes sense. If the current player finally starts acting up, they're mechanical - it's inevitable, you shouldn't be in that much of a bind to find another hi-end transport/CD player. Al... | |
| Tube and SS pairs So the system I mentioned above, ARC REF 2 (Tube) + Pass X350 (SS) + Martin Logan Ascent i, the preamp seems to be dominant in how the system sounds and while the Pass has it's own sound changing the preamp or rolling or replacing tubes in the pre... | |
| Tube and SS pairs Audio Research Ref 2 into Pass X350 into Martin Logan Ascent i. Generally I think SS amps are less critical of speaker loading than tube power amps and it’s easier to get more power and current from SS.With that said there are plenty of good tube ... | |
| KT120 back to 6550 AtmasphereBad assumption on my part. I'm guessing if the driver fails the output grids get pulled down by the negative supply cutting off the tubes. instead of just losing bias.Sorry for the misinformation. | |
| KT120 back to 6550 I think PrimaLuna and Rogue have pushed Audio Research to come up with amps like the VT80. ARC power amps normally are seriously fussy about tubes which I'm sure was no end of frustration for Upscale. They've sold enough tubes over time to figure ... | |
| KT120 back to 6550 That VT-80 is so user friendly (a really good direction for ARC) I could see buying both and rolling between them. It's only 4 tubes.You're in a really good place. It sounds like you really don't need the bass extension of the KT120. You just need... |
