IMHO, "bright" therefore means bright speakers or bright music. Sometimes amps or preamps get blamed for being "bright" but in reality it is impossible if the FR is linear. I have also hear "bright" in DAC sections which can only relate to flipping and flopping bits (a.k.a. jitter).

Or simple distortion...

Demand greater honesty and transparency in high-end audio

With Theta, Egglestonworks and Krell since 1998!

I have heard a lot of reference system over the last 20 years. There is no doubt in my soul that the sound coming from this system is the best I have heard ever. Incredible!
Not all Aerials are created equal. The 20T's are in a league by themselves. I loved the 20T's with Musical Fidelity. I can easily see why the Prometheus would synergistically appreciate the NCore / Theta topology and design approach. It's one of the best speakers in that price point.

Distortion? With current SS amps, that's below human perception.

With other amplifiers it's more speaker dependent. It's much easier to apply EQ to make either mids or highs suit your taste than to follow find an amplifier with the sonic signature you like. I take the position that amps and preamps have sonic signatures.

Yes. Amps and preamps have signatures. But IMHO nothing to do with FR.
So some preamps and amps are clearer and others not so much. If I put on a well recorded song and it isn't "bright", how can the amp turn on and off its "brightness"? Answer: it cannot.
Hence, the music or speakers are "bright" which is the FR problem.

Thank you to both of you! I was starting to wonder about my decision. Strange thing is last night the current amplifiers gave me a glimpse as they have started to remind me of the demo pair.

Since 4 hdmi ports is not enough for me with the CB4, I'm thinking that it might not be enough for a few of you as well. Any recommendations on an hdmi switcher?

CRAIG: any chance for an hdmi card with more ports?

STEVE B: do your sources go to your lumagen first, before going to the CB4?

I use Lumagen Products. The Radiance XE but they have new products that are 4K, 3D, HDCP 2.2/HDMI 2.0. You get the bonus of having a video processor too. In my case I run sources into the Lumagen first which then has 2 outputs. One for CB4 and one to the display device.

Well like I had stated before the Dreadnaught D sounds best after 400 hours! 200 hours is not enough to show what it can do! But I think you have made up your mind already Amp-Guy! Best of luck to you

I run everthing through the Lumagen XE, which has two HDMI outs. One HDMI out to projector. Second HDMI out to Atlona HDMI splitter, with one out to CBIV for audio, and one out to 55" 4k LG HDTV which sits under my big screen. Theta Compli Blu 3d has two HDMI outs, one for video going to Lumagen, one for audio going to CBIV. Also, my multi-channel HDMI media server has HDMI into CBIV, too.

Atlona makes great HDMI switcher & switcher products which auto sense the signal.

You mean you don't remember me? Back 1999 - 2003, I started and moderated the AVS Tweaks forum and also the AVS Special Guests forum.

Don't know what you are looking for, and no flame please LOL, but I use this cheap HDMI 1.4 switcher for my Kuro plasma in the living room: http://www.amazon.com/gp/product/B00...ilpage_o03_s00

It switches automatically to whichever device that is powered on, meaning most of the times I don't even know it's there. Of course, digital signal so bit is bit (tongue in cheek), therefore no degradation in video/audio quality that I could tell.

No amp can not but you can. As I have said, I once took the approach of constantly switching gear until I found combinations that I liked. Now I just feel like that alone is a very outdated approach that the typical end user will not pursue. It wasn't until I discovered how much of an effect small boost or dips can have on what audiophile consider bright or rolled off that I took a different approach. Many audiophile do in fact like a slightly elevate mid-range for vocals. That's easy to do as well. Have you tried it? I'd wager that I can hugely effect the personal preference of any of the gear you are testing, to the point of one piece of gear being chosen at a very significant rate over the other if I know the listener's bias. It's like trying to find the key to a lock by randomly selecting keys. Well that approach will work but so will just making the proper key. In years past, you had to buy a very expensive, parametric EQ, to even attempt such frequency modifications with tranparency. Now there is Jriver and other programs that are powerful tools, more powerful than amp swapping, if you use them.

Never become so involved with something that it blinds you.

The only time I want to fiddle with EQ is when I have a problem with my room. A better solution is to fix the room with treatments. I don't like touching the FR from the midrange on up. I'm particular about that. As an example, I cannot get more clarity out of a tube amp by turning up the treble. When the tube amp "filters out" the top end, that information is more hidden in the recording. As I said before, the FR is ruler flat on every competent amp ever made. Some like this "warmer" sound while others don't. You cannot just turn up the FR to compensate because you cannot bring it back with frequency.

Amps and preamps are intertwined and the logic whould have to be the same. It would be like suggesting that a person with an Onkyo (IMHO the worst sounding prepro) just needs to turn up the treble to make it sound more airy like a Theta. Not!
