amplifiers

Hello, I disassembled HCD-RG295, its an audio system with CD, Decks, radio, and amplifier, and I want to take amplifier from it and make it work with aux, but I am not very much knowledgeable of what to do to make it work. I would be happy if it had like aux, volume control, and that's all. I...

I have a Pioneer Gm-D9705 amplifier and I set the gains with multimeter for the first time when installed in my Corolla. There was slight RPM whine which increased when accelerated. Bought an Oscilloscope model DSO153 and tried to reset the gains, the waveform was jagged (front and rear...

I am curious to find out if there has been a “ruling”, study or conclusion that older amplifiers sound quality is generally better than the newer ones? (Not talking reliability) I see comments every now and then about how good a 30 or 40 years old amplifier sounds and is much better than...

Hi there, Recently been helping someone with getting better audio output from a TV to a jukebox amp which is driving both a set of internal speakers and a pair of KEF floor standing speakers. We originally fed the TVs headphone output into the amplifiers BGM line input which worked fine but the...

I have a 3 way speaker and recently i have noticed that most the sound including vocals is coming from the mid range speaker. Tweeter is like it’s not even there. My question is so in a two way speaker does the tweeter do all the work ? I mean all the sound and vocals comes from tweeter except...

As the title states I am embarking on a journey to places unknown... Well maybe unknown to me but that's why I'm here, y'all know a whole lot more. Starting off with the UM 18-22. Pretty sure I'm going the way of DIY amp and I'm going to attach a couple screenshots from this website that I...

Hi All, I'm completely new to the world of Hi FI Music and I have a question which is very possibly dumb. I have a Harman Kardon AVR151s receiver which delivers 75W per channel, as per their user manual. Currently I just have a very poor set up with 5 JBL satellites + a JBL Powered Sub...

I have a DIY project that will require a powerful amp (or two mono amps). This is for high fi speakers, not subwoofers. I am tempted to use two Monoprice 605030 amps in bridged mode. @4ohms they make about 500watts similar to using two of the Benchmark AHB2. The $ difference is significant. I...

I am new to the world of higher end quality audio equipment. I have a Carver power amp (class A, discrete channels, 100w) and preamp (1985) and they are driving Ohm Walsh Two speakers built in 1985. I now wish to move into the world of tube amplifiers. I have come across many online ads which...

Hello, I would like to compare two headphone amplifiers. How do I volume match? I have never done this and you can consider me an audio noob. I have no idea about internals or technicalities of audio equipment. My available equipment so far: -DAC: SMSL Sanskrit 10th MK2 -Amplifiers: SMSL SP200...

"Some of the high-end audio amplifiers' evaluations push my modus operandi into lab like mind-set, but there are a few of the amps that ignite the un-rational response while keeping my logical "processors" running happily. Totaldac Amp-1 is among this rare breed. Amp-1 can reveal and pull out...

I posted this on another thread but it is too interesting and deserves its own discussion. Dan is a legendary amp designer formerly from Krell and nowadays with his own company. Went from designing deeply based on measurements on the later Krell days to less reducing distortion and more...

Class D amplifiers have defined a new discipline in audio amplifier design and parameters, similarly as digital CD audio after its arrival in 1980-ties. After some time after its arrival, it was apparent that CD measurement methods would need something else and more than previous, purely analog...
