H2O Signature Stereo vs H20 Signature Mono Amps


I am in the process of downsizing my rig and am curious to learn more about the H2O amps.

Has anyone compared the signature version stereo amp to the signature version mono amps? If so, please share your findings in the comparing of the 2 set-ups?

Do the signature mono's perform that much better than the signature stereo to justify twice the price?

Is Henry coming out with a pre-amp? If anyone has info on this, please share what you know.

Are the H2O amps a fully balanced design?

I am strongly considering matching a good tube pre with solid state power amplification. If you have had success or failure doing so, with the H2O amps, please share your experiences.

Thanks!

Game on. I will take odds on that Barrelchief as I was auditioning the Rowland 201's, 501's, and the 302 (heard it, wasn't in my price range) with the Synergy IIi before I stumbled upon the H2o's.

With that said, the Rowland 201's and 501's didn't compare to the 302 (obviously) and neither did the 201's or 501's compare to the H2o standard stereo IMHO. FWIW I think the 201's sounded better in the mids than the 501's, however the 501's did appear to have better control. The 302 is a different animal than either the 201 or 501. I was told by a Rowland rep that the 201 is 85-90% of the sound of the 302. I will have to respectfully disagree. However, perhaps the refinement, etc. is in that last 10-15%... it just didn't sound that close to me.

I would contact Henry and see if he has a *broken in* pair of Signature Mono's you can audition. Make sure he is aware you want a broken in pair, as I can tell you now, the sound change is drastic between a new unit and one fully broken in, especially in the mids being fleshed out and liquid as well as the air on the top end.

I haven't had the pleasure to compare the Sig H2o Monos to the 302, however if my memory serves me correct, and there is no impedance mismatch between the Synergy IIi preamp and the H2o's I think you will be pleasantly suprised.

Are you also looking to downsize on your preamp, as that is a very good preamp...
Hi Audiofankj:

I appreciate you sharing your experience.

I would describe as my "downsizing" as being in the "big picture" and not necessarily with every component...just looking to pull out a good chunk of $ and maintain an enjoyable 2-channel system.

Yes, the Synergy IIi is a very nice pre. However, with these changes, I am very interested in matching up a tube pre with SS power amp. One pre that has been recommended to sound great w/Ice amps (after rolling tubes) is the Aesthetix Callypso. I am open to suggestions.

Thanks!
Barrelchief:

Althought I've lived with both components for some time and I've never tried them with the H2O, I can certainly recommend the Transcendant Grounded Grid pre-amp and Phono Stage as outstandingly good values for the money. I think both would work very well with the S250 Sig. Tube rollers are welcome!

I have a Supratek Chenin that sounds wonderful with my H2O S-250 on my Scintillas. BOb
I personally use the First Sound Presence Deluxe Mk II to great effect. In general it is not a VERY tubey sounding preamp, it has the superb dynamics and low noise floor of a high end SS design, yet has the liquidity and harmonics of a good tube preamp. This mates very well with the H2o Sigs.

I was also considering the Chenin / Cortese as they also seem to be a great piece as well as over achiever for their price point.

The Aesthetix Callypso was also a preamp on my radar, however I have never seen/heard one in person...
