Sundown 3500 or IA 40.1

Only testing in equal installs will answer your initial question, the 3500D is very popular and I believe there is a new 40.1 on the way.

don't rule out the RD D9 for the same power.

He means the on-paper ratings are the same but the SAZ-3500D exceeds the ratings by a higher margin. The SAZ-3500D has 33% more output FETs than the AQ-3500D, more caps in the power supply section, and a bit larger transformers.
On 12v drop-in vs. the SAZ-3000D at 1 ohm it was a full 1dB louder - so it's reactive load performance is on par with a 4kw amp or more (since it out-performs the AB VFL-400.1 as well).

If buying used... the 40.1 is still a strong amp and I have not tested it head to head vs. the SAZ-3500D.

thanks. you answer my question.

I would like the sundown 3500 and IA 40.1 tested side by side and see what happens

Also the rd 5750.1 does look nice what bout the price?

close race, guess either amp will do about the same

The ia40.1 have been proven to be almost bullet proof, that would be my choice based on their reliability.

how low can each be ran daily safely?

Why did they stop making the 40.1 I mean people talk about how good they are all the time, yet IA quits selling them. Makes a lot of seance . They have been off the market for a long time. Real smart people at IA.

I was wondering the same thing, even to make upgrades on it how long does that take

I doubt there was a whole lot of a market for a 4K watt amp. Plus they are building a new one, so we shall see what they come up with.

If the 40.1 are almost as bulletproof as the 20.1's id run a 40.1 way before a sundown. I have sundown amps(125.2s), I like the CS, but when it comes down to it, would you rather have customer service if your amp blows or an amp that wont blow:. Either is a great choice tho. Im sure the sundown will be easier on the electrical but i bet the 40.1 will do more power(especially at 18V).

Yes they did, close to 2 years if not longer ago.
