I still use this amp daily as it is on my home listening room stereo. I've also done studios and other facilities though my career.
CARVER CM 1090 PRO
I'm a broadcast and audio engineer with plenty of experience in FOA audio, pro sound, and system design and installation in many different venues. Plenty of loud clear audio.īTW, none of the preselect styles fit me. It did quite good on a pair of A-T VOA A-7As. I even used this amp as a back up on one of my jobs after I made the changes. I pulled my folder on the amp and decided to write a review. In this video, I document the troubleshooting and repair of a Carver CM-1090 amp.Here are the parts I used during this repair, all were sourced from Digi-Key. How do I remember this? I was searching on line for something and came across this site. Looking at Fresponse I found the amp to exceed ratings and Pout (into 8 ohms/C) was flat over the range at better than 100W/channel with each channel being within a few tenths of a percent of each other. I then looked at waveforms for cross-over and THD distortion. Finally I added good computer grade electrolytics with a better capacitance and voltage rating. I replaced a few of the small electrolytics with better tantilums, some of the cheaper coupling capacitors with a better grade and increased the power value of some of the resistors. I wanted to beef up the entire supply, but there is no room in the enclosure.
On the bench I found the poorly designed supply. Same thing when driven to any decent level. So I tried the amp on some Apogee ribbon speakers. The first thing I found when I started to use my amp was it would shut down on my Altec-Lansing 1204Bs I had on my main stereo. The original design used cheap under sized filter capacitors. The other reason this amp gets a 4 is the cheap power supply design. Ok, I will stop my anti-not made in the USA or Europe tirade. It has a CD direct pre-amp to amp stage or it allows you to go thrrough the preamp and adjust bass-midranfe-and treble. Even Crown and many other once fine products are made cheaply in China and sold at very inflated prices. Now would I consider any high priced China anything. Carver's patented Sonic Holography circuit opens up the stereo sound. The preamplifier section is first rate in every respect, including a pristine phono stage for enjoying your favourite vinyl treasures. For what these amps cost new and all the raves about Bob Carver I would never had bought a new one. Carver quality For those who seek exemplary audio performance meet the Carver CM-1090. I rated the amp a 4 only because it is made in China. Mine has done a great job ever since I picked one up used in the early 90s.
