Initially, I tried Reed with Koetsu Coralstone and did not like the result very much. It was ok but felt it could be better and eventually felt that Koetsu was best
matched to FR 64s which I use with Micro Seiki BL-111 table. TW told me in the past that Koetsu does not match well but did not say because they don't like Koetsu
house sound or if there is a specific problem with their table so how much was TW's fault and how much was Reed, I don't know. Anyhow, Reed 3Q works very well with Air Tight Supreme PC-1 (which I recently moved to Graham). It also sounds wonderful with Lyra Atlas. In comparison to Graham using Air Tight PC-1 Supreme, it really depend on your preference. I think Reed is the more musical arm. Graham seems to do everything right, faster, stronger, lots and lots of detail, tighter bass, big wide soundstage with very tight focus image but may be a bit on the cool side. Reed is fuller, warmer, better decay, richer harmonic, a little bit more laid back. Bass is a bit bigger but not as fast or tight a bit less transient attack and impact. Some may say Graham is more neutral and Reed is more colored which I supposed would not be wrong either but I would say colored in a good way. Being a not so competent amateur pianist with a Grotrian grandpiano in the same living room as my stereo, I feel that piano sound more natural and definitely more pleasing on Reed than Graham though.
Basically with TW Raven AC-1, it really depends on what I want to listen to. Vocal music (Mary Black, David Roth, Allan Taylor, Taiwanese singer Tchai Chin, Eva Cassidy, etc), chamber music, piano, I prefer Reed over Graham. On Rock, pop type music, I go for Graham. On large scale orchestral music, if I want to go for big impact, exciting performance i.e. Shostakovich, Mahler, I prefer Graham. For Beethoven, Mozart, Brahms, Reed has a slight edge.
I have not try Lyra Atlas with Graham to compare but will do so soon. I was told that Lyra really prefers copper over silver wire. My Reed has Silver wire so I am waiting on copper DIN phono cable to arrive before I will try Lyra with Graham as my Graham also has silver cable currently.
