I have a Counterpoint with a Hafler preamp . I have to admit I think the pre amp is on the bright side. I just want to clarify ,, I do not think these are bad speakers , they are 850 dollar speaker , I have the bubinga finish wich really makes them so much more expensive. Eric did a great job with them . My issue is ,and I even used a 35 watt tube amp , that in my taste the bass is ,,soso, not that there is not any , just not what I thought is advertised or claimed by Eric . If I really thought they were bad , they would have been sent back by now . I have about 100 hrs of time on them so I am still hoping they improve . Any suggestions for a "less brighter" preamp,amp would be appreciated . Thanks.
