INVERSE Relationship, as x factor/gain increases, the load/impedance lowers, take a good look at the single dial on this unit I posted above. GAIN in db on the outside; LOAD in ohms on the inside going the opposite direction
Recommandation for 1:6 1:8 SUT under $5K?
I’m looking for some advice on a step-up transformer that pairs well with my Audio Research LS28SE, PH9, and Hana Umami Blue cartridge. I currently have both the Denon AU-S1 and AU-340. The AU-S1 sounds absolutely beautiful—very transparent and open—but at 1:13 the gain is too high, and I’m getting some clipping, especially on dynamic peaks. Even with the AU-340 at 1:10, I can still hear a bit of overload. I’ve tried playing with loading and parallel resistors, but the issue really comes down to gain. I think something in the 1:6 to 1:8 range would be perfect, enough to keep the clarity and tone I’m getting from the AU-S1 but with better headroom. My budget is around $5k, and I’m open to any recommendations for a high-quality SUT?

Lounge Copla offers a Silver Wire Upgrade SILVER WIRELCR MKIII Silver wire will give you much more transient response, resolution and frequency extension than the LCR MKIII. The LCR MKIII Silver wire gives you more space around the instruments and more sense of pace, rhythm and timing. The specifications for the LCR MKIII Silver wire are the same as the LCR MKIII except for the gain which is 44db. The circuit design is the same for both products but the LCR MKIII Silver wire has point to point silver wire in certain parts of the audio, ground and power supply area. The LCR MKIII Silver wire also has more power supply filter capacitors and some key resistors are upgraded. The LCR MKIII Silver wire uses the same chassis as the LCR MKIII Standard option. Robert writes "silver wire upgrade" on the bottom of the chassis and signs and dates the unit. https://www.loungeaudio.com/copla "Being a small outfit, Lounge opted for the only reasonable option. They sell direct through their very well designed and informative website, allowing prices to be kept low and value beyond anything you could purchase via traditional retail. The downside is of course that you can’t listen before you buy but Lounge do offer a 15-day return guaranty as well as a one-year warranty (they even pay for return shipping in case of a warranty repair)." and here’s the video with the founder and designer, it’s fascinating, it is OPTICALLY controlled, you are simply dimming LED’s (not in the audio circuit)and that is controlling a pair of photo diodes that control a pair of transistors https://www.youtube.com/watch?v=IBnxwatJu_w I also noticed, at 2:40, the wife moves the sleeve of my favorite LP 'Friday Night In San Francisco' that I highly recommend to use to refine your antiskate.

By transimpedance, I presume they are referring to current mode, ie to attempt to load the cartridge with a dead short to maximize and amplify the current generated by the cartridge. An adjustable 40Ω-300Ω input impedance by definition suggests this is a traditional voltage amplification device and not a transimpedance one. dave |
Dave at Intact, I would never argue with you, but in this case, the OP originally said nothing about noise and only mentioned that he sensed overload when he did insert a SUT. Good point, though, about noise. Even in his latest post, the OP does not mention noise per se as an issue with no SUT, but he does say he prefers the SUT to no SUT with certain recordings. So there you go. I would never use an (original) DG recording as any sort of standard; those used to make my ears bleed. They are not just hot in terms of level but also in terms of treble emphasis. Kind of like Roulette LPs in the jazz genre. |
intactaudio, lewm, everyone I encourage watching the video, it’s a unique solution, and he discusses noise among other things https://www.youtube.com/watch?v=IBnxwatJu_w I bet big bucks the interviewer is faking his understanding, but no matter, Robert just keeps on yapping |
