The planets must have aligned perfectly….
My plan was to revisit the review of the AIYIMA A07.
My unit was put to good use in my son’s dorm room last year and now resides in his sister’s dorm room at a different university.
….

What are they studying?



…..Then I noticed this review and discussion.
I have zero interest in debating the “regulars” here and hope they can refrain from personal attacks this time…
I have been LISTENING to a pair of the Crimsons for several years.
The measurements are what they are…
It could be years of being exposed to the sound of my drum kits or dialing in the scope on my Weatherby 300 Mag…but these sound wonderful to me… just different than my MC275 VI, CF275 and the Proton D1200 I just restored….

I liked the AIYAMA enough that I have another after the first one… as does eldest daughter.

Jez - what did you do to attract attacks?
I am not sure starting off with a martyr approach is helpful… Just do the review.

I noticed that the fellow look like he is prepared, and already has a boat.

Are you sure that isn't an oven? With those handles, and the metal front with glass window, it looks like something for a trophy kitchen.
I first saw this sort of thing in China. A way to insert LED and graphics in glass. In bathroom mirrors, mostly. Maybe you can now get them at Home Depot and Lowe's... I don't follow the bathroom mirror scene that closely. I think you can pair your Android phone to the display. Read your messages along with the Sina Weibo blogs while you brush your teeth. Important time saving tasks from gadgets that make modern life worth living.

Surprised Mac hasn't gone this route. It's got to be cheaper than the real thing. Maybe their customers want and need the analog ballistics. Below is a pic. I know everyone likes visuals.

I'm afraid that Bob's boat already sailed. Not sure he was even on it.
I don’t think you can call it sailing, more like sinking.

I think that for some of us old timers, it's not a happy ending. But it is not an uncommon ending, for sure. I mean, there comes a time when we all have to say and admit that enough is enough. Like Ali or Tyson. Both interesting in their day, they didn't know when to say when, so each wound up embarrassing themselves. Ali with the rope-a-dope, because that's all he could do. Totally boring.

Mike was a bit different, and never boring. In the immortal words of Gordon Solie, he simply turned it into a spectacle, a 'Pier 6 brawl', with Holyfield wearing the 'crimson mask'. I guess an argument can be made for the cleverness of biting off an opponents ear--I don't think that had ever been done before. Although he probably should have waited until Mills had been unintentionally knocked out. In that case, when Mills woke up, Iron Mike would have stood a better chance for a win, or possibly a draw.

Bob? In the twilight of his autumn, he's simply decided on the the rope-a-dope.

Regarding high sensitivity speakers, the use case is somewhat of an oxymoron to me ? Let me explain .
In many cases high sensitivity speakers have a very ragged fr response and a bunch of other issues ( Klipsch, zu ?)
Distortion from your tube amp will be the least of your problems ?

I’ve read tread here where DIY projects seems to have high sensitivity speakers who mitigated those issues but they unsurprisingly includes active overs eq and possibly also class-D or solid state amps ?

The typical hifi speaker has not been developed with sensitivity as an priority for several decades ? When they where it was out of necessity .

You may like these speakers for sounding “dynamic” or “alive” and “interesting” I’ve heard some, but in the end prefered “normal” speakers.
High sensitivity speakers do tend to have more ragged frequency response especially if they are horns and they tend to trade low frequency extension for efficiency in the bass. Because of this, active crossovers are almost mandatory so that EQ can be inserted into the feed for individual drivers and subwoofers cure the low frequency limitation. Using EQ to tailor frequency response is not limited to high sensitivity speakers since many (most) speakers to this day which use passive crossovers and those that use DSP use EQ to tailor frequency response and voice the speaker to the house sound of the manufacturer.

There has been a shift in speaker sensitivity over the decades toward less efficiency and this was predominant in the 70s and beyond. This is because with solid state amplifiers, power was plentiful and relatively cheap compared to tubes.

High efficiency horn speakers do usually sound more dynamic and alive for reasons which people here debate endlessly. Whether they do sound more dynamic and alive or not at all is also debated here with no apparent resolution.

I have full range horns (Klipsch La Scala) and it is obvious to my ears that they sound more dynamic and alive than any conventional cone 'n dome speaker I have ever heard. People here will debate endlessly whether it is all in my mind or if I'm crazy or not but I have yet to see any of them in my listening room to hear for themselves. The high end audiophile tweakos will debate whether I'm using the correct speaker cables.

That's the kind of customer testimonial Jim and Bob are looking for, I'm sure.
Note this is not a personal attack. Hearing loss is nothing to attack; it's an unfortunate byproduct of modern life for many folks, this poster included.

I, for one, like my 99 cent resistors.
A testable hypothesis. :cool:

On topic (sort of) and FWIW: I think that the Bob Carver Corporation, or whatever the current morph of this company is being called, is selling pretty much the same basket of dreams as Nelson Pass's companies. Carver's doing it, I'd opine, in a bit more ham-fisted, 1950s-American-style way than Nelson.
Carver: "You want tubes? We'll give you so many tubes you'll swoon!"
"As many tubes as an OTL amp! But wait, there's more! We give you the OPT's, too!"

The high frequency accentuation is perfect for the demographic that buys these amps. It probably sounds closer to neutral due to their hearing loss.

EL34 and 6550 have the same pinout, but a 6550 may run away in an EL34 socket since the G1 bias voltage is lower in magnitude for the EL34 and may not hold the bigger tube off from drawing too much plate current and running away in a fixed bias arrangement. With cathode biasing, YMMV.

Great point. I am running a SFS-80 which is not a fixed bias design. The SFS-80 is built for the higher current tubes so going with an EL34 works.
In contrast the SFS-40 is built for EL34 and can be a bad idea with the 6550’s.

Woah, you might have to take out a loan when it comes time to replace those output tubes, 40 x KT120, but it has a "lifetime tube warranty", hopefully yours rather than Bobs.

Perfect for tube rolling! Just listen for the subtle differences that only the most discerning golden ear can pick up.

I can't find the power consumption listed on the website anywhere. It must be horrific, especially the current required for 110V countries. It does have that auto power saving at idle at least though.

Probably makes a reasonable substitute for a baseboard heater.

You mean a frequency response of 20-20kHz within +/- 0.3dB!
This demographic must be blessed with super hearing. :cool:
