What's Your Advice, Used Audio Research LS15, Or Freya+?


Title says it all. The LS15 I'm looking at is the older model without detachable power cord. I'm looking to dabble in a tube preamp. I'm running a Bryston 4bSST for power.

ARC is in a different universe compared to Schiit.  Schiit is built to very low price points while ARC is not.  I would go with ARC anyday over the Schiit.  The ARC will retain its value much better as well.
Over on AudioAsylum, several people have bought the Freya+ and have very nice things to say about it. At $900, it is not particularly cheap, though certainly not priced in the high-end category. 

If you want a new ARC preamp, you're going to spend several multiples or more than what the Freya+ costs, though you can get one of ARC's discontinued and much older models on the used market in roughly the same price range as the Shiit. 
Not heard the Freya but remember the ARC LS15 and it’s a fine preamp and in its day probably among the best for the money. If I had to take one without a chance to compare the two I’d take the ARC.
