Phono Stage Question.....


I am considering a Sutherland Little LOCO Mk 2 Phono stage. 

I currently run a Conrad-Johnson EF1 Phono stage, with Lyra-Delos Moving Coil Cartridge putting out 0.6 mV.  5-10 Ohms of impedance.  SME V arm, J.A. Michell table.  Preamp is Conrad-Johnson Premier 17LS, Amp is C-J LP66s,  Both all tube.

Sutherland touts their Transimpedance technology over 'traditional' voltage technology.

They state that Loading and Gain do not need to be set or worried about with this particular circuit design.

I'm wondering if anyone here has crossed over to the Sutherland Circuit Technology within their system, and is it really better than 'traditional' voltage tech.

Would you rate it 'much improved-go and buy it' or 'meh, not a big deal'??

Thank you for your thoughts and input as always....Lou

rauliruegas...thanks for your input.  It has great value.

One question not answered in the review.  Is the PS phase or non phase inverting?  Very important to know, especially with C-J equipment.

 

Sutherland, to the best of my knowledge, did not invent the idea of current drive.  As noted elsewhere, every current driven phono stage is going to sound a little different with any given cartridge.  This is my experience as an owner of a BMC MCCI, and after comparing notes with other owners of other current driven stages. My guess is that this is because none of these devices is "ideal"; an ideal current driven stage would have a zero input impedance, and that is not possible.  Hence they all have slight differences in input impedance, ranging from a few ohms to as much as 20 ohms.  This impedance will interact with the internal R of the cartridge, resulting in slightly different gain characteristics and possibly in sonic character as well.  Another factor affecting SQ is the fact that these devices consist of a current to voltage converter input that adds gain via amplifying current but puts out a voltage to drive the downstream circuit, which must be a conventional RIAA filter operating in the voltage domain, and the output is ultimately a signal voltage. Nothing is perfect. In my opinion, one should not assume that current drive is some sort of panacea for problems of cartridge loading (and only relevant to LOMC cartridges with very low internal resistance).

I’m running a Lyra Delos currently with the Little Loco II

i went from the 20/20 for the last 3 years  and have had the little loco 

for about 3 months.  There’s really no comparison

This Little Loco was the biggest single improvement I have encountered 

since I began this hobby

Every single record I  play ,plays back 

inhibited and gives me a balance in tone I have never heard.

Really this unit just trounced the 20/20

which thought was good in itself.

You Will not be disappointed 

Good luck Willy -T

 

You may want to look into the Channel D.

Not as "plug and play" and I've seen some here on Audiogon.  It's worth a look.

Most of the senior writers at Stereophile magazine us the Loco as their reference. favorite.
