Four flaws in STR integrated due to which not recommend this amp. First, remote buttons sometimes function first time other time need to press 2 or 3 times. Second, forced to rely solely on whimsical remote because the enter or select button on unit does not function at all. Third, from day one, 4 rca inputs and one usb input produced subdued sonics. Over much time Improvement took place. However I have used XLR analogue input intermittently for approx. 3 to 4 months and the sonics improved somewhat but still subdued and not close to USB level. Does not seem to me further improvement will take place. If I increase signal strength I loose transparency. Fourth, screws keeping the metal case in place are of very low quality. When opening or closing screws their soft metal grooves get wiped out. STR integrated not recommended by me.
In addition to Anthem integrated I listen to Anthem MCA 225 generation 1. First, This amp sonics are great and very good value for money spent. The sonics are great when I connect mca 225 directly to new hp desktop. Cable i use is inexpensive stereo xlr to single 3.5 mm jack. I use software volume control. Second, i have used for greater than five years and not once require repair. I service mca 225 once a year by removing accumulated dust from inside the amp.
I listen to Audirvana radio. While listening to radio Scalla on two separate occasions I had the Extreme good fortune of listening to full potential of ELS 9. The els panel created delicate, airy, very clear, transparent and 3 dimensional sound. ELS 9 give you a taste of true high end if all the required conditions are met. From the point of view of audio hardware everything was working perfect. And the internet radio signal of a excellent true high end recording was not compromised. Hence I got a taste of sonic heaven. I must mention in slightly over three years I have experienced true high end only on six or seven occasions.
I prefer the sound of only panel ELS. Not hybrid like ELS 9. Prior to purchasing els 9 I strongly recommend listening to Magneplanar 3.7i . Both are similarly priced. If you audition magneplanar 3.7i you may ask the dealer whether Anthem power amp will match with them.
ELS 9 overall presentation, my opinion, gives too much weight to low frequencies. In other words, to compensate for twin woofers, wish the panel surface area larger by multiple of 3.
