Epiphany Audio Posted January 7, 2021 Share Posted January 7, 2021 (edited) Item Condition: New Shipping Options: Pickup available but audition is not available.,Shipping is included in price. Suburb or Town: Australia State: WA Payment Method: EFT, Cash Reason for selling: Promotion RRP: $14,999 Further information: Vinyl playback makes up a significant part of our business and we didn't want the vinyl lovers to miss out. Analogue playback is a complex beats but it's inarguable that a lot of systems are let down by a sub standard cartridge. We want to change that. While this will be a stretch for some buyers we would also argue that it represents an attainable pathway into an absolute reference class cartridge for many members unwilling or unable to spend 5 figures on a cartridge. Again there are a multitude of glowing reviews on this cartridge but like many of the items we bring into Australia this allows you to stop worrying if you could go a little better and a little higher an simply enjoy the bets that modern hifi has to offer. We have 1 unit under this offer at a 50% discount.

andyr Posted January 9, 2021 Share Posted January 9, 2021 Fascinating cart - and a great review at Positive Feedback. At a coil impedance of 1.2 ohms, I would think it needs to be used with a head amp, to get the best out of it. As it has a nominal output of 0.35mV, to get the output up to what most MM phono stages like, you need 10-15x gain. Trouble is ... a 1:10 SUT delivers a load of 470 ohms to the cart, whereas a 1:15 SUT delivers 209 ohms. I would think the optimal load for the Sumile could be anywhere between 12 ohms (10x coil impedance) and 120 ohms (100x) - a head amp readily gives you the flexibility to try out values between these values. I'm slightly confused about the price? You say "We have 1 unit under this offer at a 50% discount" - and quote an RRP of $14k; 50% of $14k is $7k ... yet you're offering it at $7,499?

Andy Great Spot @andyr we had an RRP typo - thank you! Thanks for the loading information, we have recently had a query on this very topic and I'm sure others will find it useful.

bigfunhorns Posted January 10, 2021 Share Posted January 10, 2021 Hi, I supppose that you are assuming the phono stage input resistance is the usual 47,000 ohms? So a SUT with a 1:10 ratio gives 10x10 = 100 divided into 47000 = 470 ohms. But if you have a phono stage with adjustable input resistance then you can work out the best setting for your SUT and mc. For example, a fairly common 1 : 20 SUT works out as 20 x 20 = 400 divided into 47,000 = approx 117 ohms. As long as the mm input was not overloaded by the SUT output: 0.35 x 20 = 7mV.

You have the maths correct, bfh. Yes, I assumed the default MM input resistance of 47K ... I've never come across an MM phono stage which offers adjustable input resistance via a pot. (I make my own 'Muse' MM with 100K as the default - to cope with old Japanese MM carts - but allow parallel resistors to be used ... so 89K brings it down to the standard 47K ... and 53,600 brings it down to around 35K ... which wood-bodied Grado Reference models like).
