I found a Dynavector 20x2 to be a similar flavour to the DL-103 with better extension and control at the frequency extremes. It is 3x the cost though. There are great accessories for the Denon that bring its performance closer, if you want to open all your money on a new turntable... That would be my approach.
Upgrade from Technics SP25
I currently have a Technics SP25 with ATP-12T arm and Denon DL-103 and a solid, custom plinth. I think this combination punches above its weight class due to really good synergy between arm and cart. It has big tone and tracks really well. However, I am looking for an upgrade that digs a little deeper and extracts more detail. I was going to purchase a Hana EL cartridge and give that a try. However, now I have a larger budget ($2500) allocated to this upgrade and am trying to determine best course of action: eg, buy an entirely new turntable, upgrade arm and cartridge, stick with just the cartridge upgrade,etc. Any advice is much appreciated. Also, I am currently using the phono stage in my Crayon integrated amp. After experimenting with different phonostages the one in the Crayon just sounded the best .
