I was the OP on this thread and thought I’d update it after a change to my system today. I received my PrimaLuna DiaLogue Premium HP Integrated Amplifier on Saturday but left it unpacked until this morning to adjust to room temperature and altitude. I donned the supplied white gloves, unwrapped the tubes, hooked her up, and let her warm up for only 10 minutes. I then played the following:
- Gillian Welch, The Harrow and the Harvest (LP)
- Ella Fitzgerald and Louis Armstrong, Ella and Louis (SACD)
- Eric Clapton, Crossroads 2, Live in the Seventies (CD)
I have pretty transparent and precise sources - both turntable and SACD player - and unfortunately with my prior solid state amp they sounded almost clinical. The music no longer moved me and my listening sessions shortened as I quickly became disinterested. In the hopes of fixing this, I decided to try tubes again (I had a CJ PV5 30 years ago) and the PL is apparently not only the prescription but
the cure.
I play acoustic guitar and sing a bit, solo and with others, so I’m particularly sensitive to the sound of acoustic instruments and unamplified human voice.
Gillian Welch and
David Rawlings could have been playing right in front of me - the tone of his 1935 Epiphone Olympic archtop unmistakable. Satchmo has never sounded better - his voice warm and vibrant - and Ella clear and pure. All instruments sounded natural. Then I threw in a little live electric blues - Clapton playing Eyesight for the Blind. I had to turn it up and there it was - goosebumps. My eyes had been closing, my head swaying, my toes tapping throughout, but the goosebumps sealed the deal. I’m not good at using audio terms to describe what I hear (I really couldn’t care less about that). What I care about is how I relate to the music I’m listening to - am I moved, am I swept up, does everything else seem to fall away? Once I put the PL into my system all of these tests were met and I was thoroughly enjoying the music. That is what I was looking for.
I’m leaving the amp on overnight to make sure all the tubes have settled (I won’t be leaving it on thereafter) and I’ve already been bitten by the tube rolling bug (no need to, just curiosity) and have ordered a pair of Cifte 12AU7s. I can’t wait to hear this puppy once it’s broken in a bit and I’ve swapped in the new tubes. The Harbeth 30.1s are very musical and now I feel that their potential is fully realized.
My system now consists of: Clearaudio Ovation turntable/Clearaudio Universal tonearm/Lyra Delos/Esoteric E-03; Apple Air/Ayre QB-9 DSD; McIntosh MCD500; Pioneer RT-909 reel to reel; PrimaLuna DiaLogue Premium HP Integrated Amplifier; Harbeth 30.1 Monitors; Shunyata Venom PS8 Power Distributor, Venom Defender, Venom HC and Venom 3 PCs; Cardas Clear USB Cable; and WireWorld Silver Eclipse 7 ICs and speaker cables.
