Iron is fully developed project , of which Iron Pre was phase in development , proof of concept

if you're asking for (first) , that one is overkill for ACA ..... primary developed for F4 , balanced

OK...I thought as much...thanks Zen. There was a Pumpkin preamp up for grabs in the swap meet, so I thought I’d ask. I read about the F4 lovers in the related Pumpkin preamp threads, but wasn’t sure if it would fly with the ACA or the F2 that I’ve started.

I will try the more efficient used Lowther DX3 I got at the other end to see if the ACAs make bigger noise to my liking with some of the meatier recordings I like.

I’ve heard the Lowther can be shouty, but my ears are old and used to my wife’s shouting anyway so maybe it will work out.

If it doesn’t work out with my DCB1 out front I can take a shot at setting up an old tube preamp I have. All that twiddling will probably take me long enough for the iron pre to come out.

Default Current ACA Update

UPDATE - AUGUST 1ST 2018

Batch 1: The first 60% of orders will start shipping tomorrow, in the order they were placed, and the remainder will start shipping in about a week from now. Very roughly, if your order number is lower than DAS-5300 (eg: DAS-5299) and it contained only the Amp Camp Amp kit and/or PSU, it will probably ship tomorrow, if it is higher than 5300 (eg: DAS-5301) or was more complicated, it will probably ship next week.

On August 4th we will email you either a tracking number (if yours shipped), or an ETA for when your order will ship (we think about a week).

Once again, we do apologize for the delay on the second half of the orders. Arguably, we're more annoyed than you are, however please feel free to email us and vent your frustrations. The silver lining is that all the work that went into creating systems to handle this batch will ensure future pre-orders are more predictable.

Batch 2: Everything is on track for shipping on September 15th

It seems most go for the ACA with the purpose of bridging from beginning……..and that to me seems a little strange. Maybe because it is an easy build. But maybe some think it is for "quality" also. If it is to get balanced input as main putpose other solutions exist with a "native" balanced input circuit. But again it is a good education amp to try different things :-)
Interested in balanced input options for my ACA's that drive high sensitivity compression drivers. Can you point me in the right direction? Thanks.

Mitchba, I'm using a THAT Driver card from Neurochrome that I packaged up as an SE in to BAL out preamp for my bridged ACA. It works beautifully and is easy to put together.

Skip,

Nice! How much gain did you implement on your Neurochrome THAT Driver pre, 6dB or more?

Best,

Anand.
