AsciLab speakers are about to launch

Wine might be an alternative, but never tested it.

I did and it won't work because Wine can't run the USB driver. That's why I used the VM with USB passthrough.

That may serve well as a money saving feature. Get C8C, realize I don't need anything else, profit.

true. Until you read people writing reviews about it on ASR, planting the insidious seed of doubt in your mind..."if only..."..."maybe?". Classifying it as 'unrealized profit' might be a wise approach.

 

[Defi]

Let's be real there's no way the thought "I don't need anything else" is ever going to inhabit my mind.

According to news this morning, South Korean imports to USA now have a 25% tarriff for the buyer to pay. Delayed delivery can get expensive.

 

[AudioJester]

Bugger!
Its so fluid though. Wait for tarriff to drop back down and then ship it?

Doesn't look like it applied to everything. Cars, lumber, pharma mostly.

While following another thread, this post was mentioned https://www.audiosciencereview.com/...-amp-long-term-reliability.25744/post-2500459 - TL;DR it talks about the trade-offs in the Hypex MP modules, trading long-term reliability for cost and convenience—using lower-rated components and thermally compromised designs—leading to (maybe?) higher failure rates compared to higher-end Hypex or Purify solutions.

I realize that this is coming from a party with skin in the game. But still, specs are specs:
"The NC252MP / NCx252MP modules employ Aishi electrolytic capacitors, which are typically rated for 2,000 hours at 105 °C. By comparison, the Rubicon capacitors used in Hypex NCx500 modules and Purifi-based designs are commonly rated for 10,000 hours at 105 °C. This is not a marginal difference, it represents a fivefold increase in rated operational lifetime under identical thermal conditions."

Since the C8C uses NC252MP, I was wondering how this would affect their longevity. How do you see it @AsciLab ?

Not trying to open a can of worms but I ordered the C8C so this question is of direct interest to me...

If this had been a systemic long-term reliability issue, it’s very likely that Hypex would have received extensive feedback from OEMs and end users over the years, and the design would have been revised accordingly.

The fact that these modules have remained in production without major changes suggests that, in real-world operating conditions, reliability has been acceptable.

Thanks for your answer, makes sense ...what capacitor temperatures do you expect inside the C8C under typical use? is there any ventilation that prevents over-heating?

The amplifier is designed with ventilation slots on both the top and bottom to prevent overheating.

The red bold is probably not right and I'm surprised it comes form AA.
NCx500 I have seen usually use Nichicon PW 10000 hr ones (don't know if there's a difference from batch to batch)

Edit: found the pic

Not that it makes a difference, both are top-notch, just for the accuracy.

But C8C is 3-way speaker, so how come it uses a dual channel amplifier?

 

[Uncola]

Hyped fusion 253 is a 3 channel plate amp with dsp. There’s one per speaker

 

[Coltr@ne]

Three channels, two 250W, one 100W. Two subs, front and back

OK, so it is not NC252MP.

 

[pat355]

yes...
FA253: NC252MP + NC100HF

 

[somebodyelse]

OK, so it is not NC252MP.

Not only NC252MP - FA253 has one of those, an NC100HF and the DSP input module(s). We're about due for the NCx modules to reach the plate amps, so maybe some manufacturers are getting early access to those too.

Maybe the runs later this year, but Ascilab has already said they have the older gen modules.

Dear AsciLab Team,

I am writing to you today because I am honestly quite desperate.

I initially ordered the C6B in Black through Audiophonics in early January. Unfortunately, the delivery was postponed to late February, then late March. I eventually decided to cancel my order to buy directly from your website.

I have been checking your site constantly, and I saw that Black C6B stock was finally available 2 days ago! I rushed to order today, but they are already sold out again... only one White unit remains.

To be honest, I am so excited because this will be my very first Hi-Fi system. Currently, I am only using my TV speakers, and I can't wait any longer to finally have real sound at home! I have researched as much as possible to make the best choice, accumulating a maximum of data. From everything I've seen and understood, your work is just incredible.

To give me some hope, could you please tell me when the next restock for the Black C6B is planned? I really don't want to miss it this time.

Thank you for your help and for making such amazing speakers.

Best regards,

Not gonna lie, as a C6B enjoyer for the past month or two, the announcements and info drops over the past couple of weeks have gotten me thinking a lot about re-architecting my home theater solution entirely which I had capped at 5.1 for the longest time. Long story short, the MiniDSP Tide16 looks quite temping (waiting for the inevitable review) and I'm a bit OCD in wanting to use as many of the plugs as possible offered on any piece of audio equipment, so now I'm thinking of adding the C8T towers to my setup given the amazing data that was posted mere days before the Tide16 announcement.

I was already in the market for the center channel speaker that Ascilab is targeting for ~summer of this year, but the low freq THD performance of the C8T towers then got me itching to upgrade the subwoofer, and since Dirac ART was now in the picture, why not get two of them to take better advantage?? Then of course I gotta throw in a 8ch Hypex amp and that would get me to a working 7.2 solution. Oh, should also complete the corner bass trap set I have too while we're at it.

I should have picked a cheaper hobby... Then again, always willing to pay for good engineering solutions backed by science!
