Yeah, love the amp! Bob take is to go with whatever sounds better, which is what I did. It is mostly just curiosity that makes want to see the curve.

what kind of amp are using ---- brand model ---wpc --a tube amp from china , 4 ohms --
It is a tubes4hifi/Bob Latino VTA-70 with KT-66 that I built from kit. Has 8 and 4 ohm taps. Approx. 35 WPC in UL mode and ~20 WPC in Triode mode.

Understood. I have tried both taps but prefer the 8 ohm. Matter of taste I suppose.

I have CWIIIs, but I imagine the curve is almost the same at K33E. My experience with my McIntosh MC2125: it works better and the sound is better on the 8ohms terminals, because on the 4ohms terminals the sound is softer in the bass, but beware this is only valid for CWIII + MC2125 and also for my ears.
I think the wiser will be to listen to the wedding with your amp first in 4 ohms, then in 8 ohms and your ears will easily choose for you which you prefer. Technically no problem to connect in 4 ohms or 8 ohms it is just the quality of the restitution which will change.
The curve of CWIII, for the moment impossible to find the curve of CWIV on the net

Thanks fo the data point! Agree on the ears thing. 4 does sound better to me in the bass. Sounds clearer/more defined than 8. The difference it subtle though. Reason for the wanting the curve is mostly to see if it corroborates what I am hearing.

I can’t help you with the info, but if you need this to assist with pairing an amp I can tell you I achieve extremely loud levels in a 15x26 room with only 14 watts. Nice tight bass and extended highs, no apparent dips.
So my informal assessment is that the impedance curve is pretty flat.
Reason for asking is mostly to see if there are any dips that would make the 4 OHM tap on my amp preferable to the 8 OHM tap (tube amp), even though they are nominally rated 8 OHM. My guess is that it dips some in the bass, since using the 4 OHM tap seems to tighten it up some. Just curious to what the measurements say and whether or not they confirm my ears.

Title pretty much says it. Have searched for it but could not find it anywhere. Thanks in advance.

What is your budget? Have been very happy with my CW4 and a First Watt F8.

Thanks for the update! Hopefully it gets sorted and at least you know your stuff is not faulty.

have you been able to make any progress on the issue?

Hi All,
Long time reader first time poster.
I have decided to build a music listening room in my existing shop by adding two walls to build a box in the corner. Essentially a room within the room.
Floors are concrete. Two walls are already there from the shop. Walls are standard wood stud and drywall. Same with the ceiling.
Room will be music only (no AV). I have a pair of Klipsch Cornwalls that I really like that will go in that room together with tube pre- and power amp and a TT.
My maximum dimensions are 9.7' high x 17' long x 15' wide.
Given the space I have what would be the most ideal dimensions of the room?
Happy to change the foot print but ceiling is fixed at 9.7'. Open to building the two wall not parallel either, but concerned it will introduce hard to forsee issues, so most of my focus has been on box shaped rooms.
I have been reading a bunch on room dimension and acoustics but have not been able to find a solid answer. Example:
Bob Golds Mode Calculator (https://www.bobgolds.com/Mode/RoomModes.htm) suggests 16' L x 14.5' W (or 15') x 9.7' H as almost ideal
Consulting the Acoustics handbook I see: 15'L x 12.5'W and 15.5'L x 12.2'W being recommended.
The plan right now is to position the speakers in the corners of the long wall but will play around with it.
Open to room treatments and will have a rug in front of the speakers.
Would love to hear your feedback regarding room dimensions especially in regards to Cornwalls.
Many thanks in advance!

Looking for a new amp. Need some suggestions

DIY/Kits may be something to consider and will possibly get you higher quality for less money because you assemble it yourself. On the flip side you can expect lesser resale value should you not like it. Take a look at tubes4hifi.com their VTA-70 might be a nice fit. Works very well with my CW4.
