Crown XLS 1500


For giggles I'm putting together a budget system. Starting with a pair of PSB Gold-i's and using an Audible Illusions M3a's secondary variable outputs. Anyway, I needed to come up with cheap power and current that could drive low impedance upper bass, e.g. dips at around 2.6 ohms. I didn't want to toast my Rogue M120's.
After researching I came across some good reports on the Crown XLS 1500 and decided to pull the trigger for a whopping $239, new! I was hoping to get it last Thursday but no such luck. The amp arrived the other day, or a day late for the Grateful Dead Chicago run. I had to use a self powered PA for my outside, projection, big screen system. A bit of a disappointment but in the end it worked out better as I didn't have to worry about the PSBs getting messed up.
Anyway, I plugged the unit in yesterday and gave it a quick listen and cold, out of the box I was not happy but figure it needed to burn in so I kept it playing for about 30 hours and then gave it a listen. I still was not happy, feeling that it sounded rolled off in the highs, a bit muffled in the lows and somewhat canny sounding in the mids. I was starting to feel that I wasted my money and that the saying that "there is no free lunch" was true. However, I was willing to let it burn some more.
So, while cooking the amp, and casual listening, I decided to make a new run of Canare 4s11 speaker cables, which I was planning on using for the new system but felt that ultimately this might be waste of my time because it was beginning to look like a failed system. 45 minutes later my cables were done and I put them in, replacing the temporary double run of Monster XP I made, which was left over from the outdoor deck system. After install I turned the amp back on and then turned up the wick. Holy cow!!!!! All of a sudden everything opened up and snapped into place. I now had extended highs, articulate bass and clean and sharp midrange. What a difference. This is what I was hoping for when this straw was pulled.
I won't give a full report until I get some more time in but for $239 new I can already say this is a great deal. This amp sounds good and delivers watts without strain. It out does the Adcom 555 I owned back in the day, which could poop out when pushed hard. As to some of the reported noise, yes, if I put my ear right up to the tweeter there is some low, low level buzzing. I can not hear it from a foot away, or needless to say, from my listening seat.
Lesson learned; don't judge a component until your rule out other variables. My guess is that the Monster is high capacitance and caused all kind or uglies with the system. Ridding myself of these cables brought me from Kansas to the land of OZ!
For those that care, I'll report back in a few to let you know how things develop.

Yeah, I had miraculous result with star quad speaker cables before as well, also Canare.

However, do note that ground lift creates a really bad filter: http://www.belden.com/blog/broadcastav/Ground-Loops.cfm
Well, the Henry has arrived and I immediately threw it in my system. Well, well, just as I thought. Gone is the noise and gone is the need for the ground lift. Also, I now have more gain than I would ever need.

Initial impressions with the Henry in place remain as before but with a very, very low noise floor, so that this is no longer an issue and on a subjective level this amp can now be called quiet and without any noise issues what so ever.

It is a dynamic amp that has an up front presentation, that gives you incredible sound for pocket change. For someone starting out and on a limited budget, this affords them to allocate more funds for source components or speakers. It is also ideal for H.T. systems, surrounds, second or third systems, or like me, to just plain have fun with trying new things that won't effect your bank account.

It does have some limitations. To perform its best it should be run balanced or you should use a consumer to pro level matcher. Right now I'm getting good results with the Henry Matchbox HD. I would suggest not using the basic Matchbox, as it might not provide a level of performances needed for critical listening.

Also, it might not be a good match with speakers that are aggressive or up front in the mid and upper mid-range.

Back in 1986, I bought an Adcom 555 for $550. This was considered a good choice as a budget reference. In today's dollar that would be around $1,200 to 1500. The Crown 1500 can be had for $209, delivered, including taxes and it clearly beats what the Adcom offered. Yes, that is almost 30 years ago but it just shows how far technology has come and what can be had for much less money.

Does it sound better that any of the fine Classe amps I've owned or nice tube amps? Well, probably not but it won't necessarily keep you up at night dreaming for that perfect amp. Well, maybe not for a while anyway. Meantime you can buy that cartridge, pre-amp, speakers or that source component that you have been wanting.
Raymonda, you have me thinking seriously about trying my Crown XTi 2002 (which I am using in bridged mode to drive my 15" passive Tannoy sub), and try it out with my one-off Tannoy HPD 315 speakers.

Currently, I am using, for the most part, some Class D Audio amps, or for a change of pace, an SET 300B amp.

The XTi 2002 does an incredible job with the Tannoy sub. I'm going to have to try it out with the 12" stereo pair.

I agree, Crown still is a great value in this crazy, overpriced, audio world.

Dan

Sure, I would give it a try, too. What do you have to lose? However, make sure it is not too much amp for your speakers.
I demoed the XLS1500 in my system several months ago, and agree that it is a mighty fine amp for the dollars asked.
THe best sound (for me) was using the XLR inputs (I used a custom RCA-XLR IC) and the SpeakOn connectors. And topped off with soft 'squissy' footers.
The stock RCA in and banana-speaker post exhibited that harshness you are hearing. If you look inside, you will see that the banana post connects to the circuit board via a two piece plated brass metal strip which are bolted together to complete the circuit. THe SpeakOn is a single continuous silver plated conductor per pin into the circuit board.

My Stillpoint definitely was not a good match for the Crown, too 'hot', had better lock with BDR cones, bamboo footers, and soft type footers.
I also had slightly better sounds with a little conditioning.

I won an XTi1002 which I thought was more to my sonic tastes, it had a more 'juicy' midrange and fuller mid-bass. With the XLS showing superior 'air'.
I use the XTi for bass duties mostly since I Biamp.
