Eminent Technology ET-2 Tonearm Owners
Hi Guys Look forward to your impressions of the Allnic John. Harry would love to check out the Nashville music scene one day ... Of note on the loading discussions. Taken from Lyra website Kleos Recommended load directly into MC phono input: 95.3ohm ~ 816ohm (determine by listening, or follow detailed guidelines in user manual) Recommended load via step-up transformer: 5 ~ 15ohm (step-up transformer’s output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable) Delos Recommended load directly into MC phono input: 97.6ohm ~ 806ohm (determine by listening, or follow detailed guidelines in instruction manual) Recommended load via step-up transformer: 5 ~ 15ohm (step-up transformer’s output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable) *********** My XV1 has a recommended loading of > 30. I have run it full out 47k with no issues. From this thread.. There were good takeaways for me from J. Carr on that thread, from quite a while ago. J Carr Generally speaking, the greater the capacitance across the plus and minus cartridge outputs, the heavier the resistive loading needs to be to control the resulting high-frequency spike. Conversely, less capacitance allows the resistive load on the cartridge to be reduced, which will benefit dynamic range, resolution and transient impact. ^^^ It highlighted for me also, how important a role the direct shot wiring plays. I am sure it plays a big part, along with my phono stage, for the reason I am able to run with no load. Cheers Chris |
Hey Chris, Thanks for the link to that rather involved discussion of the interaction of cartridge, interconnects, and loading. I must say I'm more confused than ever, but have learned a few things. Has anyone taken into account the break in of the connection between cartridge and phono pre? With only millivolts on the cable, does it ever break in, and stay that way, if you believe in such things? I got sold on a new interconnect by "Allister" at Audioquest, incorporating the DBS system. -Never used DBS before, but seemed like a good idea for this application. I imagine it will beat my 25y/o AQ diamond IC's. An AQ water will arrive tomorrow. If it doesn't work in that application, I'll try it elsewhere in the system. I'll get back to you about that. John |
Just to add to my last post in followup; as I got curious and just finished talking with Gene at Take Five Audio who made my loom. This is in regards to the ET 2 direct shot wire looms being used. Capacitance versus Noise Where my wires leave the armtube they are separated with distance between them. There are two reasons for this. 1) The least binding effect on the ET 2.5 travel. 2) lowest capacitance. Now if you braid the wires you will reduce noise - but you will increase capacitance. It’s a give and take. So when discussing the benefits of low capacitance with loading the cart - a big part of the result will be the way the cart wires are arranged in proximity to one another. |
The AQ interconnect I acquired has a capacitance of 20 pf /foot or 71 pf/meter or thereabouts. Combined with the ET-2's cap of 40pf that's about 110 pf total. I tried it today and am very happy with the improvement. When I added the new phono preamp, -whole new level, even though the load on the preamp is pretty much fixed, at 280 ohms. -One less thing to worry about. I really like the SUT concept and am unlikely to go back. The S. Korean designer is pretty slick. The new preamp is like a hotrod. No remote etc, no bells or whistles; just incredible sound. I recommend it highly, even though it's not even burned in. I'm in hog heaven, and I even passed up the Braves game to listen instead. -John |
