Mar 17, 2015	soft thump and driver moves...even with no signal Hoping it's just some old tubes finally failing. Plan to change out power tubes tomorrow.Based on the description this is quite possibly a bad tube in the signal chain somewhere after the volume control. Its likely not a power tube.
Mar 17, 2015	Electrostatic speakers and low volume resolution This can be an amplifier problem as well. With many amplifiers, the distortion goes down as the output power is reduced- but only to a point. Below that point the distortion starts to go back up.This occurs at different points with different ampli...
Mar 17, 2015	Describe ube sound vs solid state ^^ This.Music is process in the limbic centers of the brain- unless some aspect of the sound is altered enough that the brain detects a problem- and then the music processing is transferred to the cerebral cortex.This is literally why some systems...
Mar 16, 2015	Triplanar vii - upgrade tonearm and ic wiring @Salectric: Yes. We just got the arm in our shop turntable updated. It does seem to sound better.
Mar 16, 2015	Describe ube sound vs solid state Ralph, can a ss amp have such low distortion as to make that comparison not tenable? I suppose a better question would be, have you ever listened to a ss amp without the typical characteristics you ascribe to them?I have heard one solid state amp ...
Mar 16, 2015	Help phono/headphone stage for Scout Jr. dyna 10x5 The Audeze is one of the best headphones made and your Onkyo would be outclassed.The Icon is nice and should do the job- the 110 ohm impedance of the Audeze is tricky but the Icon should be able to handle it as it has taps for a number of impedanc...
Mar 13, 2015	Triplanar vii - upgrade tonearm and ic wiring The 12" is really nice if you have a 'table that can accept it. The mass of the arm tube is slightly less then that of the original 'classic' Mk7.
Mar 13, 2015	Triplanar vii - upgrade tonearm and ic wiring Ralph, Do you really think the "old" wire interfered with tracking? That would have to mean also that the path of the wire through the arm wand and then down to the outputs via the vertical path, puts the wire in a position to interfere with the b...
Mar 13, 2015	Describe ube sound vs solid state I find tube amps to typically sound brighter than ss amps.Your experience here is unusual! The majority does not share it. This might have something to do with the speaker you are using- it might have a much higher impedance at high frequencies th...
Mar 12, 2015	Triplanar vii - upgrade tonearm and ic wiring The new wire is a lot more flexible so the arm is supposed to be able to track better. It already was one of the best tracking arms made...
Mar 12, 2015	Describe ube sound vs solid state The problem here is that often the ear will give weight to distortion perceived as tonality over actual frequency response.A classic example is the brightness of transistor amps. On the bench they might test with the same bandwidth as a tube amp b...
Mar 10, 2015	Rock and roll speakers? I've no idea why this is happening all of a sudden as there are several recent threads on this forum asking about the ideal speaker for a certain genre of music.Examples: the best speaker for: electronia, death metal, 80s rock, etc.This is the mos...
Mar 10, 2015	Power Conditioner for your amplifier? ^^ this is incorrect, here is why:Power conditioning if done right will have the following aspects:1) regulates line voltage 2) prevents high frequency noise (most electronics should be immune to this BTW)3) prevents low frequency harmonics (the m...
Mar 10, 2015	Describe ube sound vs solid state ^^ Actually Mapman this is not entirely true.Because tubes usually are more linear you can often build lower distortion circuit with them- and often without feedback. That is a lot harder to do with semiconductors!Most power transistors incorporat...
Mar 05, 2015	Cartridge impedance loading question Capacitive loading will make a difference- its the same as using a more capacitive cable, which is to say its probably something you want to avoid as it will lower the resonant frequency of the RF circuit. A capacitor can be quite useful in loadin...
