Adding a tube amp is a good idea?


Dear all, 

Hope your 2025 is off to a good start! I am thinking about adding a tube amp. Particularly Audio Research ref S80. Nicely used unit can be had for a reasonable price so I am considering it. You can see my virtual system for a full list but my system consists of LTA preamp, Pass Labs X250.8 amp and JA Perspective2 speakers. Totally happy and satisfied with the sound I get from the system, but just want to have another amp for a different flavour. Do you guys think ref 80s sounds different enough, for better or worse? Let me know what you think. Thanks

I certainly hope so because I’m about to build a little 6L6 tube amp for my 95db speakers. I’ve driven them with small Pass DIY Class A SS amps. They have such a sweet sound, but now I want to hear what tubes do. I’m told 6L6 tubes are particularly clear. It’s fun to play with such different gear.

The amp is an Elekit 8200R from Tube Depot. It’s supposed to arrive today. It comes with JJ 6L6GC power tubes and the usual 12AU7 inputs. A guy in our local audio club built Elekit’s 300B kit - went all in with the WE tubes and other upgrades, like Lundahl output transformers - and paired it with 93db speakers. I’ve heard it and it’s wonderful. I’ll probably set my amp’s jumpers for ultralinear (8 watts pc) at first, since my understanding is it’s optimized for that. You can also choose triode (4 watts pc) and pentode with the jumpers. The thing also has an auto bias circuit that adjusts for different tubes, so you can pop in EL34s, KT66 and other, similar tubes. I’ll feed it from my DAC at first and then from my Pass diy preamps and see what works best. It’s got a volume control of its own. I’m excited. Hope I don’t fry myself with the voltages these things operate on.

The speakers are DIY bookshelves with one 6.5-inch full-range driver each. I sourced all the parts from Parts Express. I searched for an 8-ohm speaker with 90+db sensitivity and carbon fiber cones (just because I like the sound of Wharfedale speakers and figured their woven Kevlar cones had something to do with it). I was a little shocked they sounded as good as they do. No, they don’t make much bass, but I added a little Martin Logan sub I got cheap and it all works together nicely. The setup is just for a family room we spend a lot of time in, so it’s not intended to be the end game system.
