Koetsu vs Dynavector

I have used neither of these cartridges despite being, as a VPI dealer, able to get the Dynavector at a favorable price. I have used some of their predecessors and can agree that they are going to sound quite different. Also the room and characteristics of the system will have a large effect which is hard to predict. If I ever fell on my head and as a result was willing to spend big bucks on a cartridge I would get a Koetsu Red, but then I use transistors; so the Dynavector might well be the better choice with your tube system if you follow the principal that you balance rather than reinforce the rest of the system with the cartridge.

You guys make me think I'm going deaf. I hear no significant roll-off of the treble (compared for example to my CD player) with my Koetsu Urushi. I live in the Washington, DC, area. If anyone wants to come hear my "rolled off" system, please contact me privately. Bring records with which you are familiar. It might be fun.

What would you like to know about the Rega? None of the commonly done Rega mods alter the arms characteristics in any meaningful way. The effective mass is the same with the mods as without. The dampening is the same with or without. Until you get into some of the radical mods that are really beyond the average consumer (drilling the arm to change the mass or filling the arm with dampening material) the basic characteristics are fixed by the basic design. But in the interest of complete disclosure. The arm is a basic RB250 with the Incognito wiring kit that has been upgraded with Eichmann RCA jacks. The counterweight has been replaced with the Michell TecnoWeight and the arm has been fitted with the VTAF Teflon upgrade to allow easy optimization of VTA. The arm has not been stripped of its paint as I am suspect as to how much dampening a thin layer of powder coat can supply, so I haven't bothered to take the time to mess with such things.

In terms of the Mod Squad Phono, I can't be that much more specific. I don't have exact gain figures for it and I am not really sure they would supply much additional info anyway as I also don't have a gain value for the amp. If you are implying that total gain may be an issue, I would agree with you. That has been a concern with both the lower output Koetsu and the Dynavectors. The confounding variable here though is who do you believe in terms of cartridge output. The Koetsu Vermillion lists at 0.2mV on the KoetsuUsa site but the Stereophile review of said cartridge list it at 0.4mV. So I guess overall system gain is indeed a sticking point for our discussion but I don't think there is any easy was around this. The other criteria that you may have been looking for is loading for the cartridge. The Mod Squad has variable loading but off the top of my head I can't remember the values. The loading is easy to change via a simple knob so I suspect that I could easily find something that was at least in the ball park for most cartridges.

Currently I am a bottom dwelling of the cartridge world. I have a Grado Reference Platinum and a Zu modified Denon 103. The Grado is on my old Oracle Alexandria and the Zu is on my Lenco L70. The Zu is a bit of a challenge for the phono stage but it seems to get by without to much trouble but I will admit that I don't have any room to spare on gain. I love the Grado with voices. There are much more reach out and touch them than the Zu but the Zu has a propulsive sound that really keeps things going. I like the Grado for the majority of my listening as per my previous posts I gravitate to smaller scale vocal work but I must admit when the urge to crank up some classic Hendrix or Clapton strikes I would always lean towards the Zu. I intend to keep the Zu around and perhaps get a transformer to allow me to use it into the MM stage of the Mod Squad.

Hope that clarifies things enough to satisfy the detail oriented posters on this forum.

Don't think I forgot anything relevant.......perhaps only that my favourite colour is orange.

Well like everyone else here my opinion is worth a cup of coffee when you throw in $1.00.

I have an Oracle V with turbo supply, IO signature with two supplies and volume controls and use USA monitors and PK 57 ESLs. So our systems share some similiarities.

I have used a Dynavector 17D3 and now use a Koetsu Rosewood Signature Platinum in a SME V.

Your room is enormous and I listen nearfield no more than about 9ft, back of the speakers. I think the Dyna and Koetsu are quite different and yes every Koetsu up to the RSP may not sound rolled off in isolation but plug in Platinum or any .2mV stone model and you will hear eery shimering detail that is haunting and missing from the others. The Dynas are faster overall. Can't beat that midrange and the top end in the (higher end .2mV) Koetsus. Top end is not as extended as some of the very expensive Clearaudio though for example. Bottom end is challenged somewhat but with quads and the right amps there's nothing like quick planar bass.

Stretch your budget and go for a stone model Koetsus or the RSP it should give you most of what you are looking for.

In short...High end Koetsu's climb toward absolute TECHNOCOLOR!
in short...Top Dynavectors are "archeologists" of sound!

Think about it.
