Can't people just, you know, spin a record or something?

Computers should be illegal.

You realize you could be setting off a troll war over turntables with that advice.  :icon_lol:

That brings up a good question, how does the 1200AS2 sound with vinyl.

Here's a few impressions I posted yesterday:



These threads are so convoluted and digressive it's difficult to find the listening impressions.

I don't see how. Everyone knows the best tables are direct drives, with the Technics SL1200 being the pinnacle of vinyl playback.

Tru dat.

Thirty five pages on the thread and I'll wager less than 2 or 3 pages with any useful information.

Yes. Not that it was a forum mainly audiophile.

In any case I will update the first post as others manufacturers appear and there is more information about the current ones.

Since most forum readers are from the US, what you should list is the landed costs of each amp. That includes shipping, tax, duty and brokerage fees. This can work out to $200-300 on top of shipping, from Europe to North America on these amps. All of my amps have no duty, tax or brokerage fees on top of them for US citizens. What you pay at checkout is all you’ll pay. And shipping is 1-3 day Express.

Maty, note that the Apollon and NORD prices include austrian and UK VAT. The Rouge price is without italian VAT, which is included at checkout for EU customers (Apollon and NORD instead subtract it at checkout for non-EU customers) adding 22% and price of the Rouge Studio-10 reaches 1012,60€. Also, missing is a comparison of the connectors and internal cabling (Rouge has good quality baseline optione, that keep price low, similarly for NORD, whereas Apollon starts with ETI binding posts that would alone cost 100€) - and many other differences.

120 on a pallet. If they sold 120 and only have 30 coming, it's going to be an issue. Especially since Icepower know's what they're up to now.

icepower dug themselven into a hole by not thinking properly about logistics. They blame allocation issues in the electronics market (which DO exist) but they also did not have a proper multiple components sourcing strategy before they decided to bet their future on the new IceEDGE chipset.

They have pissed off many customers and I believe they would sell them the rest anyway - when available.  They cannot afford to lose clientele.

Takachi case Icepower 1200AS2 blowout sale

I've been thinking about these 30 Takachi cases I have with holes pre-cut for the Icepower 1200S modules, and what I'm going to do with them. I was going to save them for later, but I'm thinking now why sit on inventory? So I decided to sell them off as completely assembled 1200AS amplifiers. They will all only come with my standard level cables and connectors. This includes Neotech OCC copper input and speaker cable, Neutrik analog input connectors, CMC pure copper binding posts, and Mil spec silver plated copper power cable.

Pricing will be $899 for silver, and $939 for black. Contact me on my home page for more details:

You don't pay tax on the shipping cost. And actually you don't pay tax on the labor either. All I put on the customs invoices for European clients is $599 for silver, or $639 for black. Unless anyone has a problem with that. In that case I can make it as high as you want.

And I don't use Fedex. I use DHL. There's no clearance cost.

So:

$599 purchase price  487€
4% import duty on the above amount = 19.44€
21% VAT = (487+ 19.44 x 0,21) = 106.4€
Shipping cost 81€

total = 730.6 + 19.44 + 106.4 + 81 = 918€ Shipped to your door in 4 days all cost in!

Notes to make the article/post.

We can make some cheap and easy improvements. Case, cables and maybe RF/EMI filters + ferrites.

Today I have comment about cables, star quad cables off course, in the DIY class A 20 watts ALPHA amplifier. Design of which I am more and more impressed every day and not only for its fantastic harmonic profile with very low noise, but this is not the thread. My problem, my loved cheap tweaked KEF Q100 coaxial speakers: 4.7 Ohms minimum impedance but I suspect sensitivity more near to 84 dB than 86 dB of specs -> they need more watts.

Pre-Tin Plated Steel

Pre-tin plated steel is an ideal low cost solution that works well from lower frequencies in the kHz range through frequencies into the lower GHz range. Carbon steel has a permeability value in the lower hundreds range which provides the low-frequency magnetic shielding property that is missing in alloy 770, copper, or aluminum. The tin plating offers corrosion protection for the steel to prevent rusting as well as providing a great solderable surface to attach the shield to the traces on the surface board during assembly.

The most common material used in the manufacture of chassis for consumer audio equipment is electro-galvanized cold rolled steel.  This material has the capability of providing adequate electrical and mechanical strength for many applications...

Example: my 3 mm electro-galvanized cold rolled steel



With 1 mm is enough. Verified with my AV Yamaha.

Just received the Nord Two SE ICE1200AS2 stereo amp. Letting it run in at the office for a week and then home to compare to the Hypex amps.
