| MAC Autoformers? ramtubes I also would like to note that the OP of this thread, Paul R owned a RM-9 Special Edition. We miss Paul, a really good guy. Totally, "top bloke" had many late night discussions with him. He really loved his RM-9 Special Edition which he... | |
| Autoformers, The Benefits in matching amp to speaker While some may consider a transformer a band-aid, I consider it a device that makes the problem go away. I totally agree with Roger’s summation for autoformers, they are an "answer looking for a problem." A bit like having rubber roads and lookin... | |
| Autoformer vs Speaker impedance Curve ramtubes Second, modern SS amps already have good current capability and low output impedance. They "don’t need any help"And I’ll add to that, they will also make that amp sound worse if used, as I’ve proved to myself with 3 or 4 amps that were ... | |
| MAC Autoformers? ramtubes Ralph,I did read your white paper before entering this discussion. Lets just agree to disagree. Peter Walker designed the 57 to be used with an amplifier with a damping of 20 and even specified the series inductance. To say that these s... | |
| Need to recap my Classe Audio DR-8 Amps - need suggestions kdross Here is a post on re-forming, this guy knows more about electronics in his sleep, than some of the aggro know all's here. " Electrolytics will have a very long shelf life.But will NEED to be reformed slowly to achieve their specified par... | |
| Low power tube amp for Sonus Faber? ei001h OP Also if your interested ei001h here is an A/B of the JC5 vs the $8.5K McIntosh MC452 "Tonally, the MC452 and JC 5 are nearly opposites. The MC452 is more organically textured and warmblooded. It has a denser and more colorful tone. The... | |
| Low power tube amp for Sonus Faber? ei001h OP I’m not sure how to interpret those numbers. Also have an option to get an older Krell ksa300s, not sure if it’s superior to my Mc452. What do you think ? My plan is to have one SS and one tube for Elipsa. I’ve never been a fan of soli... | |
| Low power tube amp for Sonus Faber? ei001h Low power tube amp for Sonus Faber? Mastersound 845 compact for my SF Elipsa SE. It uses 2 845 Valves, single ended at 30W per Channel https://www.stereophile.com/images/archivesart/1207SFEfig01.jpg" the speaker is still a demanding load... | |
| Need to recap my Classe Audio DR-8 Amps - need suggestions kdross Don’t listen to Kosst and waste big money on new caps, your amp are hardly used as you say.Just take it to a good tech to get them re-formed, he knows not to power the amp, he’ll just use a big variac the bridge rectifiers and the supply ca... | |
| Need to recap my Classe Audio DR-8 Amps - need suggestions Caps that need reformed are garbage and should be replaced. This is not correct, I’ve done it many times with new old stock Siemens that have been on the shelf for 15 years or so, and other good quality ones, and I’m sure the ones in the Classe a... | |
| Need to recap my Classe Audio DR-8 Amps - need suggestions 1: If you have any dc offset coming from the amp, you may hear it at switch on by a good hefty thump through the speakers. 2: And if it has a constant large amount of dc offset you can as gergeab said measure it with a DMM if you have one and know... | |
| narrow and wide baffles and imaging Yes, the IRS V had a very large baffle. But Arnie Nudell, physicist that he was, curved it back to minimize the effects of diffraction. It was also to re-enforce the bottom of the midrange so it could be xover (mated up) to the bass towers withou... | |
| Need to recap my Classe Audio DR-8 Amps - need suggestions kdross I recently purchased two Classe Audio DR-8 amps. The amps were barely used and are in mint condition, but I think I need to have them recapped due to being over 20 years old. No not really seeing they were barley used this should be tried... | |
| Autoformer vs Speaker impedance Curve One thing George is ignoring here is that in a Mac, the autoformers are inside the feedback loop One thing Ralph is ignoring here, is if the solid state Mac was deigned and built correctly, it wouldn’t need autoformers, inside or outside the fee... | |
| Theta Miles CD player handymann OP Your Theata Miles is classic old school R2R Multibit (PCM63 dacs) this is why you still like it for Redbook. Trouble you've got is the laser (Pinoneer PEA1343), it's almost unobtainium, and the ones around demand huge prices. If y... |
