  1. The new site seems great, and is tremendously improved when used with my iPad. I know that this new carversite took a lot of work, so I say THANK YOU TO: Nahash5150 - Administrator Gene C - Administrator B-Man - Administrator Daddyjt - Moderator Balok - Moderator Zumbini - Moderator Doh-R - Moderator DennisMiller55 - Moderator

  2. Our guide for quality does have a baseline in audio - fidelity. For example, if we knew for certain that we owned a power amp that was ideally faithful in reproducing the audio signal into a speaker without distortion or coloration, then we would be listening to the highest quality component we could ask for. The reality is that power amps are not ideal, they distort into a complex load, like a loudspeaker, in various degrees. The 'tube sound' for instance is, like I have stated many times before, is the tendency for the amp to resist changes in output impedance due to complex resistance changes in the speaker. Pure SS amps struggle with this, and can clip quite easily. Tube amps struggle with high output impedance, thus causing microphonic effects and speaker cone ringing. There's a lot to know about audio. There's a lot of science, experiments and engineering lessons that we all have access to. What I don't like to see is people sticking to their own way of thinking simply because it's what they are used to thinking about, then offering up a cop-out like 'we all have our own opinion' or 'everyone hears differently'. While those are true to some extent, that shouldn't be the end of the discussion. How can you ever know for certain your way of thinking is infallible? Isn't it reasonable to support your views with objective, verifiable measurements and formulas? We should strive for knowledge with the resource of this forum, not simply yak to each other how we think audio should be. Because really, if there's no sure way to arrive at quality, and fidelity, and therefore ultimate carefree gear, then we're just wasting time talking about it all.

  3. The measurement of 'quality' requires a solid, agreed upon definition of what 'quality' is. That is not possible. We can measure certain aspects of quality but because quality itself lacks certain definition we cannot agree what such a measurement would be. In the best selling philosophy book of all time, Zen And The Art of Motorcycle Maintenance, author Robert Pirsig posits that 'quality' is the interaction between subject (sound) and object (the listener). That interaction is necessarily different for every listener simply because no two listeners are exactly alike. Therefore 'quality' remains an abstract without an agreed upon interaction. It lacks control except by the individual.

  4. When I don't know how to explain my observations with measurements, I post them here in hopes that someone can enlighten me. Often I am tutored by members here and find objective ways to describe my experience. Sometimes even the brilliant people here are still searching for objective explanations. Sometimes I have to rely on my senses in lieu of currently unknown objective methods of measurement. In those cases I state my own opinion and it isn't a cop out. I welcome constructive, objective comments. I haven't seen any indication that anyone here claims to be infallible or blindly refuses to apply objective methods when they are known.

  5. Insert picture or video You have likely noticed there is no "insert picture" or "insert video / YouTube" buttons on the New Topic composition toolbar at the top of the post box. You can either copy/paste or drag n drop pictures directly into your post so long as they are jpg / jpeg / png or gif files. Your image will first appear in an 'upload' window at the bottom of the screen, once the upload is complete, click on it and it will load into the body of the post at the point of the flashing cursor. As you add images they will all appear in the upload window. Resizing is available directly by left clicking on the inserted picture and dragging one of the corner frame points to change the size. Also, you can edit the uploaded picture by double left clicking on it which will bring up the 'Image Edit menu. Direct image links Web images: right click on the image and select copy image then paste directly into your post. You do not need the image link location. Resize as required. YouTube Videos Click on "Share" on the YouTube page. The highlighted link will appear, copy and paste. There is no need to get the embed code now. Removing images If you are editing a post and want to remove an image, You must to go to the Uploaded Images box at the bottom of the page and delete the image there. If you delete it only in the body of the post, it will not actually go away.

  6. Vacuum tube amps, due to their high output impedance making them current sources, are affected drastically by the impedance curve of the load/loudspeaker. Solid state amplifiers, especially the more massively parallel ones with large numbers of output devices, appear as being close to a pure voltage source. They are nearly impervious to the changing load impedances of a loudspeaker. Some early SS amplifiers of poor design also behaved in unexpected ways, such as breaking into oscillation, with certain loads.

  7. That's a unique look Steve but too reminiscent of what I see in the mirror after I drink. You might want to try an RGB LED on the next one so you can change the color to match your mood.

  8. He hit each and every point I thought of. Sound Quality is also very objective. What I like could sound like crap to someone else and visa versa.

  9. What you don't see is discussion between the Residents on anything that has to do with the up keep, policy discussion, ect of the site... What you didn't notice is nothing has changed. All the threads you have ever read or commented on are all still there. There are no ratings.. the Irku has been gone for a while now, your either here or your not. It looks like your still here... This is a new road we are heading down that does not hinder any members or membership here. I'm sure you have noticed lately that everything has been cordial on both sites. We are all playing nicely together for the most part, so in spite of what has happened in the past things have taken a turn for the better. Lets be happy with it.
