phono stage / step up for Koetsu carts


Now that the hunt is over, Koetsu be it. Can anyone here share info on which phono stages you guys are using with the Koetsu cart ?
How about step up transformers ?
I read that these Koetsu are sensitive to loading and optimal is 100 ohms.
thanks again for the info.
all the best....

Hello,

I use a Koetsu Rosewood Signature Platinum. Syntax is correct IMO , SUTs are very expensive, the good ones. Those folks that use the middle of the road SUTs might not have highly resolving systems to notice the artifacts they impose.

Manufacturers use SUTs to avoid a lot of very difficult design decisions and complexity where active circuits could be used. Admittedly, active circuits that are capable of handling LOMCs are very complex and subject to a host of sonic and environmental woes if not executed properly.

In my experience,I never met a SUT that could outperform a properly executed active device. The problem is: you have to pay dearly for the active device. You or I could more than likely build a SUT from scratch or component parts that would work... building an active device would take quite a bit more formal and practical education that the average audiophile would have.

I've tried my hand at DIY and I've built SUTs and active devices that work. I have also experienced home brew active devices that might rival some commercial endeavours. In the end it is about how much money, time and effort your are willing to invest and what compromises you are willing to endure. Time can teach a lot as you experience both sides of the equation so that you have enough practical knowledge to sit on one side of the fence or the other.

I use a Aesthetix Io Signature with two supplies and a Klyne 7. I could live with either, the Klyne is cute.

Good Luck!
Can you guys share which hi end step up transformers you are referring to ?
So far I only know of Bent Audio, Lundahl, Music First Audio, Koetsu step up, Ear MC4, MC10 Liveline (Hashmoto), Bob's Devices.
Any others you guys can share ?
This is an old thread but if somebody found the TE Microgroove "noisy", there was a problem somewhere else. I have one now and the system (with 100 dB/W speakers) is dead silent - nothing. I have to have my ear right ON the driver to tell if it's on.

Tom Evans' gear in general is as silent as it comes.
I've had excellent/best results with Koetsu's straight into tube preamps at 47k - magic with my Marantz 7 ( mounted on a Zeta tonearm ). Have had experiences with vintage Altec step up's - you really need to try before you buy, but my experience with most preamps using built in transformers is that they are restrictive. Sold Klyne headamp to Koetsu owner and he was very happy, preferred it to an Audio Note transformer.
I am getting good results using a Choir Audio H-7, which
uses Hashimoto transformers.
