New H20 Signature S250

Lloydf-

How many hours do you have on your amp now? I ask because in my case (similar dynamic speaker load as yours) the amps seemed to take much longer to break in than those with more demanding loads (such as those driving Apogee's)...

I experienced significant improvement after the first 50-150 hours, and continued improvement well into 500 hours, and the last bit of the vocals becoming fully fleshed out and tube like was close to 800 hours if I recall correctly or so.

Keep us posted on how they evolve with time for you, please. I may be looking into a S250 for a secondary system in a few months... thank you for your input.

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.
