SET v. Pushpull


I did a search and didn't find any threads on this topic.  I am a newbie to tubes - I have a Tavish Adagio phono stage, and I am looking to add an integrated tube amp into the analog chain in my system - I have never owned one, so my knowledge level is low.  Right now I am running KEF LS50 speakers, but they are a little small for my listening area so possibly looking at larger speakers - I was very impressed by the Joseph Audio Pulsars I recently heard, as one example.

Anyway, most of the integrated tube amps in my price range are seem to be push pull, although the Line Magnetic is SET.  At a high level, I understand the push pull design gives higher output power than SET, but also higher potential for distortion.  

Any practical experience with the pros and cons of each?  And how important is this in the overall scheme, in real world applications?  Say, compared to the choice of output tube?

Thanks,


Tom

A nicely restored pair of Dynaco Mk III's will work well with your LS50's. PP 6550's and excellent transformers - 60 + watts from a proven classic design! Competitive in SQ with today's much more expensive tube amps!
No budget was mentioned. As one data point, I have heard the LS50 paired with Prima Luna Premium HP amplifier (the 70wpc model) extensively and I thought the sound was excellent albeit a bit bass shy.
Guys, thanks for these responses - to add:  My budget is going to be $5K or less, and because of real estate issues I don't have room for tube separates, or monoblocks, - need to go with an integrated.

Herb Reichert at Stereophile has paired a SET design, the Line Magnetic 518ia with the KEFs, with good results.  22 Watts, supposedly. 
Did he state how far is he sitting from them?. His room also plays a role. 22 watts for 83 dB is low. You want your amp to be operating at 50% or lower to achieve peaks of 97 to 100 dB swings given the impedance swings of your speakers. 

May be hybrid integrates?.
