New H20 Signature S250


After reaading a lot of reviews about these amps, i emailed Henry to build me (2) S250 to biamp my speakers, I have an immediate response from him and this is what he say:

Hi Patrick,

The Amps are the Signature Stereo which has an addional Big Toroidal
transfomrer which makes it a true dual mono design, for $300 more which
makes the amp now $2800. Of course, The amp is improved over the
regular stereo across the whole Audio Spectrum. If you want the regular
version stereo, let me know.

Thanks for the number and I'll try to give you a call sometime today.

Henry

Does anyone yet owned this amp?

Audiofankj,
I've probably got less than 50 hours on my S250, so far. The Von Schweikert's aren't broken in yet either, so I was absolutely floored by how good the combination sounded right out of the box. I suspect that everything will improve with time. I'll keep you informed on my progress. I have one last question for you. I've had the First Sound Presence deluxe at the top of my Preamp wish list, but I'm not truly a tube lover. I much prefer the crystal clear more analytical sound and dynamics of most SS preamps. I've listened to a demo of the FSPD with my speakers, but not with this new applifier. In your opinion, how much would I be giving up going with the FSPD? I've asked you this question before, but in your travels, have you found a particular preamp that would get me closer to where I want to go? The Boulder preamp has the sound I like, but I can't afford it.(Atleast, not with a clear conscience.) I've read a recent 6 moons article on the Brazilian Audiopax Model 5 that sounds interesting, but the chat groups or other reviewers haven't given it much traction yet. I could order it blindly, but I hesitate to do something like that. Your thoughts would be appreciated.
Lloydf-Since your not looking for big name remote controlled preamps you might be interested in the Reflection Audio Quantum. Unfortunately there aren't many out there so the reviews are few if any. Don't let the battery power supply turn you off, it really works well.

The builder is a great guy and worth a phone call or an email to discuss what your looking for in a preamp.
Hello:

My turn to jump in. I also have recently stumbled into finding out about the H20 amps. I have the Acoustic-Reality eAR II amp with the Jeff Rowland Synergy IIi preamp... driving a pair of DALI Helicon 400 speakers. (I can recommend the JR preamp with an ICE powered amp since it seems to have both SS and tube characteristics.) But after reading the discussion forums and the 6 Moons review, I contacted Henry (a very nice person to deal with I might add!) to inquire about getting the H2o Signature for audition. Apparently the shipping box for the audition unit has been trashed from all of the handling so Henry had to a new box to the person who is currently auditioning. I'm hoping to get the unit any day and can report on my findings. By the way, what is the warranty on Henry's amps and how long does it take to get one from when the order is placed? Thanks.
Welcome to the party, Grk. I came to H2O by way of the eAR II as well. H2O amps have a one year warranty, parts, or mechanical. From what I've heard, delivery can be made within two weeks. That's not Gospel.
Hi guys. The Signature upgrade is definitely worth it. I'm one of Henry's original "launch customers" and early last year purchased three of his S250s for tri-amping my Apogees. Well after a few months I started bugging Henry to try taking the S250 to the max..a signature version. After several months of phone calls and strategizing, he came up with stacked transformers, better caps, faster diodes, silver wiring plus other goodies. Right around X-mas, Henry said he was ready to give it a try so I sent my three amps back to act as guinea pigs. They had turned the 500-hour corner and were really opening up so I was a bit hesitant but boxed them up.

Boy am I glad I did! I'm at about the 1000-hour mark on these guys and they are definitely more open and transparent than the originals. The bass in particular is now very tight but bouncy and meaty too. I feel no need or desire to re-install my Tact amps and this is very high praise indeed. Excellent all the way around.

They DO need lots of break in. Henry actually sent me new amps as he really liked how the others sounded and wanted to use a couple of them as demos (which people keep wanting to buy!). Right out of the box I really didn't care for them but I knew better. I break amps in by running TV sound and cable fm thru them 24/7 so I can build up hours fast. After 100-150 hours their tonal balance settled in but the imaging was vague. At the 300-hour mark, things were much more organized but also still a bit "dark". The next time I listened to them seriously was at about 600 hours. Man what a difference! Very open & dynamic. And now at the 1000 hour mark they are superb and very artifact free with that sense of reality that the Tact amps have when driven via their digital inputs but with a DRIVE the Tacts don't have via the big Aps.

Like the Tact amps these guy really do benefit from being plugged into my PS Audio P-600 and then individually fed thru an ultimate outlet.

Perhaps tomorrow I'll get the chance to here one of them driving a friends big Sound Labs (currently being fed by the Parasound JC-1s). That should be interesting.

Jeff
