crown pro amps?

[oldschool]

I have been thinking about trying a crown k1 amp for just 2 channel hifi,i was on the crown forum checking it out,and saw people use these for home use.has any body here used these amps for stereo,how they compare to consumer amps.

I use some older crown D series amps at home....

I like them alot

I used a pair of K2's and they did fine. As far as consumer stuff I found I liked some other amps better for full range reproduction. For the price vs performance they are pretty good.

I still use my K2's for sub duty and I like them just fine.

i love the k1 and k2 they are the best amp for the money. i personally havent run into anything i like better especially in the low end.

K series, good for LF! For serious home hi fi sub bass duty, good choice, because the K,s have no fans, easy on the electric, and alot of power!

For full range, though, I find the K,s to be a bit harsh in the HF.

Hi OldShool
About 5 Years ago, I upgraded to a Crown Power K1 for my old 030 system. And I have been am very pleased by it's performance. And last year, I embarked on a very major audio upgrade and I have found the Crown K series to be excellent choice for powering low frequency drivers.

But, I also ran into a very interesting and funny problem with the crown K series amplifiers. This problem presented itself, when I used a crown K1 to power a pair of 2446 HF drivers. The amplifier would act very strangely. And I noticed that this problem would only occur, when I was listening to music at very low volume levels. The K1 was acting like there was some kind of a noise gate built into it. So, I contacted Crown about this problem and here is their explanation.

When a crown K series amplifier does not recieve any input signal for a period of time. Then the amplifier will go into "Sleep" mode and it will shut down its power supply. This is done to reduce power and the assocated heat load on the amplifier. In older models of the K series amplifiers, this time period was only 5 seconds. While, in the newer models, the time period has been increased to 56 seconds. For owners, like myself, of the older K series amplifiers, it is possible to have this time period increased to 56 seconds by any crown authorized service center.

Since, the 2446 drivers have a sensivity of 110db per watt and at very low listening to levels, the power used is so very small, my K1 was cycling in and out of "Sleep" mode.

As a work around to this problem, I now use the K1 to power some lower efficiency 2012 drivers and the power supplies are able to staying awake during bouts of low volume levels. Oh, my solution for 2446 the drivers, was to use 2 crown D-75A amps in wired in bridged mono mode –sweet.
