My Sonic Labs

Has anyone used this cartage the ex or the ultra and can tell me the differences or if they think it is worth the money compaired to others.
What table/arm are you mounting this on? Their carts have been on Japan's audio mags short list for quite a while. A friend of mine had an Ultra on his Raven AC-1. I think he had a $10k Koetsu on another arm. One arm was a Graham Phantom, and the other was from Da Vinci. It's been a while, but I remember that the Eminent Ultra came across as somewhat cooler and leaner in the midrange. Everyone was leaning towards the Koetsu, but My preference was for the MSL. I thought for Jazz, it tightens the sound a bit more.

Basis debut and a Vector 4.
I have the Ultra and spent some time with the EX before that. I very much enjoyed the EX, but when I had the chance to hear the Ultra in my system, it was not a hard choice. The Ultra adds better clarity and extension. The bass is more extended and controlled. I would not call either cartridge "lean" but they may seem that way when compared to a Koetsu. The resolution, particularly in the upper mid-range and the higher frequencies was better with the Ultra. The sound stage and the instrument detail were notably better as well. I think the EX is an excellent cartridge, to say the least, but the Ultra sounded just a bit better all around in my system.
I think the ultra is getting a bit out of my range so I may just go back to the drawing board. Unfortinally I am totally lost here and just have no frame of refrence and no dealers to guide me. I am also a little worried about the lack of service for them in this country and the fact that you can't really rebuild them.
I haven't heard the two compared but I do have a Ultra paired up with a REED 12" arm, I went with this combo after going over to a freinds place and hearing the same combo numerous times and really enjoying what I heard every time.

Over all sound characteristics will differ like with any cart as there are so many variables that come into play, set-up, settings, associated gear and on.

My friend also has a Lyra Olympus paired up with a Shroeder Ref arm, another wonderful arm/cart combo. Listening to the two I found more similarities than differences but really still haven't been able to put my finger on it but found myself enjoying the REED/Ultra combo more so I went in that direction for one of my arms.

There are lots of carts out there to choose from, for myself I really need to hear before dropping any coin on such so I can fully appreciate where you are coming from.

Getting info. as you are is still only a stepping stone and no garantee's what so ever and just opinions, I have found over the years if possible best to try in your own set-up or at least hear in a set-up.

Good luck and have fun!
