What is the next Phono Pre-Amp for me?


I currently use an ARC PH3SE phono pre-amp with an ARC LS 25 L/S.
My cartridges are Lyra Helikon (reg output) and the Benz med output MC.

What would you recommend as my next step up?

Herron? The Groove??

I am open to suggestions!

Thanks...

What interconnect and speaker cables are you using? An upgrade in cables may improve the sound considerably.
Thanks all! My ARC PH3SE is running well and I am happy with it..however, just wondering what is the next level "up". My speakers are Infinity RS 1-B's and amps are ARC VT 100mkll and Perreaux 2150 for base.
I just upgraded my active servo crossover (big impovement) and changed all my cables (IC) to Acoustic Zen...Silver, Matrix and WOW....This was a major improvement.
Speaker cables are Alpha Gore and I am considering Zen there also. I have not heard the Aesthetix IO (heard good reports on it however.....or The Groove or Herron.....just interested in what the next level up would be?
I recently upgraded from a PH-3se to an Aesthetix Io. There was a huge improvement with the Io and that was with a Benz Glider. I am waiting for my Helikon SL to arrive- can't wait to hear that cartridge!
The following are excellent:

Aesthetix IO Signature
LAMM LP2 Deluxe
Manley Steelhead

I have tried many others and these are my favorites. If you hit the lottery, the word is that the Boulder is unreal.
herron vtph... in particular is one of the best matches to lyra as anyone would say that aestethix io is a great match for the benz. i'd say it can uncover an "artifacts" of that cartridge as no other phono-stage. in-fact if you've got a possibility you can verify that fact...
