Crown released a new series called the XLi. It lacks the X-Over and Limiter functions and adds true .775 sensitivity (user selectable between .775 and 1.4 volts). So should be friendly to consumer AVR's and DACS.

Prices start at $249 for 200WPC at 8 and 300WPC at 4 but I believe they are 1 Khz ratings.


An audiophile likes to talk about how much they spent and how good it sounds.

A DIY'er likes to talk about how little they spent and how good it sounds.

Hmm, $849 on eBay for the xli 3500, much cheaper than the two Emotiva XPR-1's I was thinking about for the same 1,000 wpc....

Just noticed that there's no rating for 2 ohms, unlike their XLS series. Would these not be good for Martin Logan electrostats?

Well, Crown responded to my email:

"The Xli series is a basic entry level amplifier without any of the extras. It is the entry level before the XLS series. It is not rated to 2 ohms stereo or 4 ohms bridge."

Oh well, my hunt continues...

The specs for damping factor are given from 10 Hz to 400 Hz (>200), for what its worth. Makes me think it does not have a 20 Hz HPF, but we all know what happens when you assume (Bad News Bears reference, ass-u-me).

I like that is has RCA input with appropriate levels, many pro amps have RCAs but not with the right input sensitivity. The 2500 looms nice for a pair of sealed 18" Dayton subs. To bad the amp testing crowd seems to have departed the forum.

Just hooked one of these up to my Denon 4311. RCA from my pre-out lft and rt to RCA in on the Crown and mains in with banana plugs. All I'm getting is major BUZZ. Bad amp?

Thnx...

Try the XLR connections. I've read people getting ground loop hum from the RCA's sometimes. Just a thought. Or you can try ground loop hum eliminated and see if that works.

I will try to p/up some XLR connects today and try that.
Which volt setting should I be using? The 1.4 or the 0.775?

Thnx......

If going from rca to xlr then use .775; if all balanced use the 1.4.

Thanks guys. The XLRs and the switch to .775 both helped immensely, but I've still got a slight hum.
Not sure what's left.

Edit: It's just 1 channel. I can't hear it with the music playing but it's there. You get close you can hear it. My wife of course hears it across the room.

Try switching channel 1 to channel 2 and see if the hum goes with it or stays with channel 1. That will tell you if it's the amp or the wires. If it's the wires you can use a ground loop hum eliminated.

You can lift the shield at one end of the cable on a balanced connection and that should break a ground loop.

Have you sorted out the hum issue?

Yes. A ground wire resolved the hum issue. However my Denon 4311 shot craps immediately after that and just 30 days out of warranty. It's been in the shop now for over 2 months. They say they can't get parts for that receiver anymore.
Is this true?
I'm really not ready to buy a new receiver. It won't be a Denon this time

Thnx everyone that contributed here.

Planned obsolescence, some MBA should be "proud" of their contribution to the world. My refrigerator is facing the same problem in that the part that needs replacing is no longer available.
