Looking for Help - LS27 or SLP-05


I've been an equipment junky for 30 years as you can see by my feedback. Its been my hobby since I was young. Now as retirement is nearing, I'm trying to put together a system I can stick with. I've searched and read threads and reviews and I still don't know which way to go. I've owned a couple of ARC preamps and have really enjoyed them. I've never owned a Cary. My current system is exaSound e22, Rowland Capri, Pass X250.8 and SF Olympica III's. I am running a 5m Nordost Heimdall 2 from pre to amp. My most memorable (favorite)sound was an AMR DP-777 direct into a McIntosh 402 driving Cremona Ms. My system does need tubes. The midrange is nice, but it is missing something. I don't feel I'm getting the most from my speakers. I know you can't tell me what I would like, but I'd like to hear some comparisons or advice.

My SLP-05 is a treasure. It uses 6SN7s (I imagine the ARC uses 6922s or 6H30s),which to my ears is generally a "ballsier", richer, bigger sounding tube - particularly in this circuit, but without sacrificing air or detail. It sounds as if this may be the ticket for what the OP is seeking.

I've not heard the LS27 and am not denigrating it in any way - ARC is a venerable firm which produces many superb components.
Thanks guys. I went with an SLP-05. I just got it hooked up this evening and it hasn't taken long to understand why you responded the way you did. I love it. It is perfect with the rest of my system.
Oh dude... vgrubb... you gotta get a philips mini watt for the rectifier... it is amazing.
I have some NOS Pope Holland 6SN7's that I used in my SLP05 before I sold it. They made quite a difference. They are not presently for sale but I could be persueded
Can't go wrong with a First Sound pre amp. Four tubes, separate power supply, just a tremendous piece of kit. Coupled with a Cary ph 302 phono pre and you've got a winning combo.
