Datasat RA7300 and RA2400 power amps

post #1 of 37
Thread Starter 
I thought I would start a thread for these bad boy amps offered by Datasat to match their amazing RS20i processor.

This is Morris Kesslers finest amp design and also his swan song.

I have heard these amps powering a 7.2 Wisdom audio system and they are ultra detailed. Possibly the most detailed amps I have ever heard.

I plan to put my order in for one of the 7300s in a few weeks.

Who already has the Datasat amps, who plans to audition them for their next amp purchase?



And a pic of the rear end of the RA7300. If your in the UK my friend at Premier Audio Video has these in his demo room along with the RS20i and Aerial Acoustics System 1, SR3s and Leon Vaults.

What is that 7300 going for here in the US?
post #3 of 37
MSRP for the RA7300 is $13,995 and for the RA2400 is $11,995.

Wow - you guys don't half get stuff for a good price on your side of the pond! That makes the 7300 £8,750 (sterling) in the UK, but the actual UK list price is £14,400 (or $23,000!!!!).

Wow. $8000 to power rear and side surrounds 4 channels)... if passive! I'm looking for 300-400W for my surrounds and heights. Any less costly ideas?

Easy to pick up the "B-Stock" ATI's at a good price: http://www.classicaudioparts.com/index.php/amplifiers.html?p=2

I tough audio quality was also important. Why compare ATI with Datasat? Not saying ATI doesn't sound good, but we are discussing different worlds.
Ans anyway, who ever spends his cash on an RS20i will want their matching amps, i don't believe anybody is going to connect ATI.

Given your post, I assume you are not aware - the Datasat amps are made for them by ATI?

Oh, i dunno... Because Jeff specifically asked for lower-cost alternatives to the Datasat-branded amps?cool.gif

No i was not aware. Anyway, they must be different. ATI must have a different design. And like i said RS20i owners must prefer to match them.

As an RS20i owner, I have no such preference! The amplifier designs appears largely similar for most of the OEM amps ATI make, including those for Levinson, and others.

So you use ATI? Compared to the design of the RS20i, they are not so good looking, in my opinion, they look very industrial...

No, I don't currently, I have custom built amps made by AB Systems. Don't get me wrong, the Datasat amps are superb for sure - my point was really that you shouldn't dismiss other brands simply because they don't have a matching Datasat badge on them - and certainly when you have no knowledge of their design or performance. That's not a criticism by the way, simply a word of friendly advice . . .

And i accept your advice and i tank you also for the explanation. Do you feel that if you upgraded to Datasat Amplifiers you would improve your system in anyway?

The ATI AT3007 in fact looks to have similar specs to the Datasat RA7300...

That's is impossible to answer without me doing a home demo and an A-B comparison. Given how close my AB Systems amps in my HC are to the Levinson amp I have in my stereo set-up, I would wager the difference would be relatively small. In my stereo system I would certainly pursue such small differences, but in my HC, where the audio is a smaller proportion of the focus of my overall attention, for me personally the price differential is better spent elsewhere . . . not that I wouldn't mind testing out a Datasat amp at home one day!wink.gif

Tank you for your explanation, i will have pretty much to read these holidays wink.gif
Tell me something, for Home Theater do you think RBH Reference are good speakers? In what league they should be considered?
I was checking the S-8300/R; S-6300/R; C-6100/R

Maybe also is that '3007' and '7300' makes for a nearly a perfect anagram - slight of hand?tongue.gif
post #19 of 37
Not so much slight of hand between those 2 amps, but I tested the RS20i with the CAT design similar to the RA7300 and my own personal ATI 2007: they all sound the same.

Not the same capabilities, but same sonics.

ATI sound quality lacks for nothing- especially when we're talking about surround channels.

ATIs closest design to the Datasat 7300 is the newly released 6007 signature edition.

Main differences. Datasat has intregral fans rather than relying on heat sinks so the Datasats can be stacked on in a rack. These fans only activate during times of peak load.

Datasat only has balanced inputs via xlr and db25. The 6007 doesn't have db25 but has RCA inputs as well as xlr.

Else the two amps share a very similar amplifier topography except the Datasat has improved psu, caps and a few other bits.

ATI make some of the best amps in the world, they make amps for CAT at $20k a pop.

I will hopefully be making an ab comparison between the RA7300 and ATI 6007 later in the year.

. . . and knowing you have a good ear for these things Nick, I'm very much looking forward to your comparison!

What about their recently released signature amps?

Thanks Gareth. Happy New Years.

I'll get a mate round when I do get both amps a do it properly with blind testing.

Really do hope to get up to yours when you do your dac shoutout.

If you notice in my first sentence I mention it's the signature edition.

Missed that.. smile.gif That would be a worthwhile comparison.

Is there any benefit to DB-25 vs XLR?
post #27 of 37
No, just special for the Datasat connectivity- gives you the ability to use a 25 pin cable for 8 channels to be connected to the amp. Trust me, Morris does the same stuff inside his amps- he has a very specific methodology. RCA, DB-25, XLR; they all get treated the same once the signal enters the amplifier.

DB-25 is mainly found on pro gear (RS20's cinema heritage?) to add more XLR inputs. I don't think there is any benefit really other than less cables?

Absolutely none sound quality wise. As for density when laying out a chassis, there are of course big benefits in space savings and that's what they are used.

No benefits to db25 sound quality wise. I was merely stating differences between the two ATI designs.
