Welcome! I have no real experience with these speakers so I can't help but I'm sure others will chime in soon.

Looking forward too! Eventually hooked up to Klipsch Chorus II's. Supposedly~ 101db 1w 1 m.  Almost on page two of the 'list'  [smiley=icqlite20.png] Our son ordered a week or two after us, his will be hooked up to his new Klipsch Forte IV, 99db. I think we're all going to be in business! ..and welcome Matt! [smiley=beer.g

Welcome to Decware

How big is your room. your speakers are very efficient ( like my La Scalla's ) so the next issue is how much space you need to sound pressurize.

Both of our speakers are great in big rooms and can fill them with sound. they also sound great in smaller ares like a more typical living room.

I just received my Torii Jr V2 with 20 watts and it is more than enough to drive you out of my room

Room
17X20
10 ft sidewalls with another 4 feet to a rounded ceiling.
and I set about 12 feet from my speakers

Hope this helps and enjoy the music

I don't have Khorns but the SpeakerLab SK clones which should be close.  I bought them with the thought of upgrading them with the Volti corner horn upgrade kit.  I too thought I would biamp them.  My listening space is huge.  It's a large L shaped room with a staircase that comes up midway thru the bottom of the L. From the front wall to the back is approx 30ft.  The speakers are about 18ft apart and I sit maybe 13ft from the front wall.

I was truly amazed what a SE84UFO could do by itself.  87DB is loud and clear with no perceptible strain.  The back part of the L opens up into a kitchen an it still sounds good even in there.  

After hearing them in place I haven't pulled the trigger on the Volti kit.  I'm just not missing anything.  I do have two small MK sealed subs to fill in the bottom but I'm a deep bass head and it's more of a fun impact thing than a true sound thing.

I'm running the PSAudio DirectStream MK1 DAC directly into it and using the  DAC remote volume control and inup switcher as a preamp.  

I just went to a stereo store and tried to listen to their box speakers.  I couldn't do it.  The corner horns is so open and unrestrained they sounded like the sound was coming from a box

In my mind conrner horns and tube amps are the ticket. I just swapped out my SE84UFO with a dyankit ST70 which does provide a richer sound but I haven't seitched back to hear what I gave up to get it.

Hello Mattwardpictures,

I've been using Decware amps with a pair of 1978 Khorns, AA crossovers, for several years now and it's been a blissful experience. The Khorns are set in the corners of the 20 x 14 x 8 living room, separation of 20 feet. The current amp is the UFO25 with typical volume controls turned to 9-10 oclock. The Khorns don't need much to fill a room this size to capacity. I've used the UFO2 and Dennis Had Inspire amps as well with equal success. You're in for a treat.

Mike

Hi there Mike.
I'm glad you're getting great results with the ZTA, and in a room of comparable size to mine. What kind of music are you playing through them?
I'd spring for two of the UFO25, but the price jump from the UFO2 makes that not a realistic option for now. (Although I've got plenty of time to change my mind and/or save up in the interim.) Is the '25' really that much better?

Hi Matchstikman!
As efficient as the Cornwall III's are, I'm sure their conventionally loaded 15" woofers liked the extra juice.
Was the difference between the SE84UFO and Torii more than a matter of impact? Is there a 'house sound' to the Decware amps, in that they all have a similar character about them?

Thanks to all for your comments so far!

Woah... keep us posted on that Sarah 300B, Mike!

I considered the Sarah as well, because I already have a couple pair of 300B tubes on hand for my current amp.

The larger reason I want to move from an integrated amp to separates, and two power amps in particular, is to close the distance between the amps and speakers, to keep the speaker cable runs as short as possible.

I experimented with different furniture arrangements to try and make things more convenient in the living room, using cable lengths from 12' to 30' in my trials. The longer the speaker cable runs got, the less dynamic and lively the sound got; and it couldn't be cured just by turning the volume up either. It was kind of a slap in the face to the Klipschorn's very reason for being---their visceral impact and immediacy.

With an integrated amp, the shortest cable runs I can achieve are 12' in my room, and there is very little slack in them. So I'm committed to the plan to run my K-horns with two amps. (Two stereo amps, for bi-amping reasons as aforementioned in an earlier post.)

Two Sarah's would be sweet, but I still have to set aside dough for a good preamp.

Active equalization, room correction and time alignment of all three drivers is the Holy Grail, and if the DDRC-88A from MiniDSP wasn't sold out due to semiconductor shortage, that's what I'd be shooting for. The DDRC-88A really is designed to be an active crossover for custom 3-way main speakers plus stereo subwoofer system. (If I happened to get stereo subs at some point.)

The MiniDSP SHD (still currently for sale) can time align and room-correct for four channels (Highpass L/Lowpass L, Highpass R/Lowpass R), so that might be a viable option if I'm sure subs won't be added in the future.

But for now, I'm happy to make do with passive bi-amping.

I currently have Jubilees bi-amp'd with Ufo2s.  Jubilees require 4 channels of amplification so bi-amp was mandatory.  I started with Fortes moved to AK6 then to the Jubilees.  I also have a tolerant wife.

I drove the AK6s with a single Ufo2 and was very happy with he result.  I was on a path to the 300B with the AK6s when I received an offer I could not refuse on the Jubilees.  Too spendy for me to bi-amp with 300Bs.

If the concern is volume of the AK6s with a single 2.3w Ufo2, I found that I could make that combo uncomfortably loud if I wanted to.

Yeah, I totally get the Clarkson on the shoulder whispers.  Not sure what your room logistics are and what the cabling plan is, but I located the ufo2s close to the speaker with the sources some distance away.  The ufo2s have xlr input available as an option so I opted for that.  End result was short speaker cables with longer xlr interconnect runs.  Worked out well.

Set-up, distances etc etc.. can be a real pia. Especially for those of us that don't have a dedicated room. Ours is the living room, as most are. We got lucky with our home many years ago. Even looked for one that we knew would work for our system..to include the surround speakers. Being from an area in the sticks, we got very, very lucky finding a home at all...especially one that would work a bit easier for gear placement. Great post Matt and responses too. Awesome, helpful and knowledgeable folks here..  [smiley=icqlite20.png] ~Mike

Awesome Matt. Completely agree. And having the speakers over the tops of chairs couches etc..surrounds included.  [smiley=icqlite20.png] Stay warm over there in Michigan. A little nippy at times here too. Pretty 'nice' March morning though.  https://www.youtube.com/watch?v=IPKs2Quk6Ts

Hi Joey,

I haven't auditioned the Volti Rival or La Scala, and all I can say about the latter is parroting other people's reviews and opinions.

However, if you have the cash and the right size/shaped room to place them in, Klipschorn AK6 is an endgame speaker. Cornwall IV's aren't bad either! (I don't know if you've heard of Paducah Home Theater TV on YouTube (https://www.youtube.com/@PaducahHomeTheaterTV/videos), but if you want to get a sense of how different Klipsch speakers compare and contrast to each other, they're one of the best resources online.)

As for the doorway, is it on an adjacent wall or the front wall? I was worried that I'd have an attenuated bass response because I've got an archway on the right side of my living room that my right channel speaker sits inches from. Perhaps this can be confirmed with measurements, but in the year and a half they've been in my house, I've been having too much fun to care that much.

YMMV, as they used to say. I'd predict that the distance from corner to doorway (31") would not matter that much, since the speaker is going to be tightly wedged in the corner anyway. Or with just enough clearance to be able to adjust toe-in to your listening position.

Hope this helps!

Joey,
In what ways is the Zrock complementing the character of the SE84UFO2? And how did the 25 fare against that combo?

It is amazing what years of seasoning does for these amps: after years of heavy use they are better, no question in my mind.
