U can listen them for hours and hours!

This is great amps. I build mine with 572-3s on output. One of them just died (after 1 year). When i was building them there were some problems with missing parts in kits. But they send them to me. Other than that, I'm very happy! First i hooked them up to Paradigms - no luck! They are too heavy for them. But then I've decide to try speakers from Sony boombox and i was blown away! Don't smile. So Ive ordered Fostex fe-208 drivers to build speakers. Meanwhile Im listening them on Sony with Subwoofer and guess what? still didn't finish Fostex project, thats how good they are. If you like me, spend all your life trying to find Nirvana among Solid state amps, then the search is over! Get them!

Reveals everything that is flawed in system

I bought these monoblock about 6 weeks ago. I put them together myself. This took me about 30 hours of work. It is doable if you know how to solder and know something about electronics. My package missed tow resisters and terminals but they were send to me quickly.

The sound of these mono amps disappointed me at first. I started looking at the rest of the system. I replaced my OEM interconnects with a couple of pairs Home Grown Audio
cables. This cleared out 98% of the grunge that was in the system. Unfortunately the system with my Pioneer CD-65
sounded shrill. On advice I replaced the 6SN7 with
New Old Stock Tubes (RCA 6DN7). Now the system sounds
very warmwhile still detailed. You do not need more
than 12 Watts with medium sensitive speakers (my
room is 20'x16').

At the moment I would say that these amps can compete
with any other amp under $5000. These amps sound very loud.
Bass is very strong and detailed. Highs are extremely
transparent.

My current system:
Pioneer CD-65 Elite.
Home Grown Audio Interconnects
Audio Electronics AE-3 Pre amp
Audio Electronics SE-811
AudioQuest Type 4 Speaker cable
Celestion A2 Speakers

Summary: I think these amps represent one of the
best values in High-end audio. Consider upgrading
the first stage tubes (about $18 a piece).

Tremendous clarity, fantastic soundstage and realism, plenty of power for a SET amp

The only one I can come up with is that unlike the Velleman K4040, it does not have a B+ delay circuit. As with most tube amps, there is room for tube rotation over the stock tubes. But that's to be expected.

I assembled my SE-811 from a kit. A word of warning - unless you're a seasoned kit assembler and knowlegeable about electronics and electronic components, buy the assembled version. The assembly instructions are geared to the level of an advanced assembler.

The assembly took me about 15 hours per monoblock and I only had a couple difficulties 1) a terminal strip was missing in one of the monoblocks and 2) a power transformer's primary leads were not labeled correctly. But I overcame these issues quickly. I used silver bearing '44' flux Kester solder in the entire signal path and normal 63/37 Kester '245' flux solder on the power connections.

The quality of the parts is excellent - much better than I have seen in any other tube amp kit at this price. Solen and oil-filled caps where needed in the signal path. A nice brushed front panel and sturdy chassis to boot.

I had some reservations about running my Bohlender-Grabener RD50 ribbons (88db) with these monoblocks due to typical ribbon current requirements but the SE-811s drive them clear and strong!

I replaced the stock Chinese 6SN7s with 1944 vintage JAN-CHS Sylvania VT-231/6SN7s and the JJ E34Ls with JJ KT88s. The KT88s vastly improved the dynamic range and sonic richness of the SE-811s and got rid of the E34L artificial brightness. The JAN-CHS Sylvania VT-231/6SN7s resulted in great accuracy and detail. I may also replace the 811s with 572s in the future but it may not be worthwhile (and worth the money...)

With this tube lineup, the SE-811s produce the best dynamics, clarity, realism, and soundstage in the absence of coloration of any tube amp I have yet listened to.

Given the price range, a SOLID 5 stars!

I want to follow up on my review a while ago.
I still support my 5 star rating. I still have not
heard a better amp under $5000. This amp really
has a tremendous performance. I upgraded my
celestions to self build Newform Research variety.
I found that the sensitivity of the speaker is
a little lower and that the bass started clipping
earlier. After I replaced the EL34 (Chinese no name
brand) with Sovtek KT88's the bass came back much
stronger and more powerfull. I would yet caution with
this amp not tu use speakers with a sensitivity lower
then 90dB.

If you have the right speaker this amp may be
one of the finest choices available.

these are my first single ended tube amps and I have yet to find a amp or amps that sound so clean. I have not tried a 300B amp yet but would like to. My room is 15 X 15 so power has not been a issue. My present speakers are triangles titus, this is the best sounding setup to date. Other speakers I have used include Kef Q60s BW 302 mirage 7si,all worked well with this amp.The 811 amps have been 100% reliable and I give them a solid 5 stars.

What a wonderful time to be part of the golden age of tube audio products! From the very exotic to the reasonable, which leeds me into the review of the Audio Electronics SE-811 class A mono block amplifiers, which are reasonable and sane. Audio Electronics is a subsidiary of Cary Audio, which markets and distributes tube and solid state amplifiers and preamps in kit or manufactured form. The SE-811's offer the most musical integrity for a single ended amplifier, than any other amplifier for a reasonable price. Kits are $1199 a pair and assembled for $1499.The SE-811 is a three tube design using the 6SN7, EL-34,and 811-3 thoriated tungsten filament triode, INEXPENSIVE for tube replacements, and which is a thrill to watch these tubes glow. The amplifier is rated 12 watts pure class A, switchable into 4 or 8 ohms. Can drive speakers rated 89db or higher, weighs at 42lbs, dimensions are 8inch high, 16inches wide and 14inches deep. These amplifiers offer the most glorious tube sound I have ever heard with deep impact, wide sound stage with plenty of front to back depth.
Summarizing the following:
TONALITY-superb vocal and instrumental timbre
DYNAMICS-sonic punch with deep bass control,this one will surprise you
RESOLUTION-superb silence between instruments, quick, clean attack and release
IMAGING-very vivid, holographic soundstage, enjoyable and discerning
TIMING-solid rhythm and pace, plenty of bass presence, NO boominess
Overall, this amplifier is a pleasure to behold and listen too. The quality of parts, chassis and the ease of building the kit from a scale of 1 to 10, ten being the best, I would rate it a TEN. The front panel is a 3/8 inch brushed aluminum finished panel, potted transformers, silkscreened lettering and black powder coated chassis. Strong and sturdy come to mind, this was a kit I really enjoyed for the perfectionist at heart. One small point, watch for any AC ground loops, to reduce AC hum, I had to float the earth ground with a cheater plug.
Equipment Used:
Monarchy M22C D/A Converter, with line amplifier, highly recommended
Sony 779ES used as a transport
Anthem CD-1 for a tube output
AVA Fet/Valve tube preamp, this one is a winner for full function and musicality

I will write a part two to this review, using a biamped setup with the XM-26 tube crossover, SE-1 and SE-811 amplifiers.
