what specific sonic improvements does 150K input impedance show compared to 38K, using the same resistor brand/materials?I can answer that. The benefit may be to your preamp, especially if you have a tube preamp. The higher input impedance will mean that the preamp is making less distortion which will translate to smoother sound with more detail.
LSA Voyager GAN Amplifier
Just got mine last week. After 24 hours of play all I can say is that this is not your father's class D amplifier. There is not one thing about its sound that reminds me of the class D gremlins that I do not like. The low end filled in and now has deep impact, the midrange is the love child of a beautiful tube and clean hybrid amp - just gorgeous. Highs are very clean and extended. Spatial cues are top notch. My system has had some damn good tube and solid state amps in it before and it has never sounded this good. I am blown away with the quality of sound coming from class D amplification at this price point.
This 300 wpc amplifier is a real winner.....

HIgher impedance sounded better using a 50 ohm source with 10 ma of class A bias and two feet of hardwired at one end low capacitance cable. Just more jibber jabber......the only thing that matters is that the final product sound good. This is what people want to know. These tiny details are held as super important..... usually by those invested in being experts. There are so many factors that make an amp sound the way it does. It is infinite....just like us. |
yyzs said...”So nice not to have to hear the hiss that was driving me batty on some quiet music with the 07x. If the CODA 07x did not sound so good I would have sold it long ago because I find it a real pain to use.” I don’t know why you keep harping about the 07x being so noisy when myself and others have already stated many times that ours our dead quiet...I’m sure something is amiss with the preamp. To be fair to Coda and the forum members...please send it back for a checkup instead of repeating the same old thing over and over. |
viber6Viber as I thought, Ricevs answer to is was his own jibber jabber, with no facts as you asked. And Ralph’s chime in that wasn’t asked for, (almost seems like an auto technical protection response for ricev) is a coy smoke screen to try to turn things around again with using the word "may introduced" and "tube" (high output impedance) as the active source. This was the correct thing to say "Changing the input impedance from 38k to 150k will do absolutely nothing if the "active" source has a "normal low’ish" (say <150ohm) output impedance that will drive both" Both of these are guys bothers in arms protecting their own interests only, it obvious from a mile away. |
George's first rule of behavior......must attack them and belittle them....then I will feel better about myself. Trouble is, it does not work. It just comes back to you......whatever you put out. You put out negativity.....that is what you get.....you put out love......and that is what you get. Pretty simple. I love you, I love you, I love you.....guess what I get back? Maybe not from you at this point in time.....but your soul loves the fact that I love and adore you.....it does. You're my baby......kisses and hugs. |
