Single Ended-Parallel or PP Class A Tube Amp?

Hi Guys,

Need some opinion and advise which is better in terms of warmth, sweet tone and near live sound. A Single Ended-Parallel or Push Pull in Class A amp (around 20wpc). Tube reference will be either 6L6GC or KT88. It will drive an 87dB / 8 ohms loudspeakers for jazz, acoustic and vocal music.

Thank you in advance for your inputs. :)

87db is a little weak for 20 watts. It will only get you 90db@2watts, 93@4, 96@8, 99@16.
That doesn't leave much for dynamic headroom or solid bass. You will feel like you are missing something.
Single ended triode may sound the weakest. I'd go for 50+ of Pentode or ultralinear at a minimum with those speakers.

Whether or not your speaker has smooth impedance and phase plots and was designed for low/no-feedback tube amps are the most important pieces of information.

That and the volume level & room size.
