Looking to move to a Tube Integrated setup

I don't disagree with that.  Measurements might help to predict certain aspects of music reproduction, but in the end the true test is your ears and the enjoyment you derive from your system.  Good luck on achieving your goals.

As an alternative integrated tube amplifier, consider one of the Audiomats.  They start with Aloha, Arpege, Aria, Adagio, Opera, Solfège.  Here’s a link to their webpage

The North American rep is located in Canada, Pasqual Ravach.

i have lived with two of their integrated amplifiers, the Arpege and the Prelude Reference MKII for almost 25 years and they are wonderful products, really solid, utterly reliable and musically outstanding.   I think they are priced below their real value.  Check out any of their reviews and you will find them very positive.  They are sadly not well known in the US.

if your speakers are that efficient the amp that will beat everything else is the Audio Note UK OTO SE. You can get a phono version as well (the phonostage is MAGIC). 3k used should get you a nice example with good tubes. 7K is approx the retail price. Cheers!

@jijoh123 I recalled this same recurring question about "which amplifier" to use with versions of the Tekton Moab in 2020. Impedance was the overarching concern. Link is below for your reference. 

The Moab owner determined his Moab speakers were truly running down in the 3 ohm range. This will take a capable amplifier to drive those drivers properly in order to evoke desired result. Most tube amps like 8+ohms loads. If you have the same version of the Moabs, maybe find an amp that can do 2ohms without breaking a sweat fwiw. Confirming your speaker impedance load matters here. Best of Luck.

jenglemann "Having dealt with some tube amp anomalies after installing the Tekton MOABS, I decided to measure the actual resistance and found mine to measure 3.1 ohms.
When I moved the speakers to the 2 ohm output terminal on the amplifier, it resolved the issue.
The amplifier manufacturer suggests not tapping for loads less than the output tap rating. Again, this is a tube amp. Might measure your MOABs to see what the actual load is on the amplifier. Also keeping in mind that the resistance can drop when being driven hard. This could be a factor in choosing a new amp.".

I would add the Cary SLI80HS. It's been around a long time, built like a tank, excellent customer support.. It has all the sweetness, finesse and grunt you could want. 80/40 WPC either in Triode or UL.  Easily found here or on USAM starting in the mid 2k, or buy direct from Cary, discounts often. I bought mine direct from Cary with most of the upgrades, only one i didn't choose was the binding post upgrade, which I regret not adding...

Mine is paired with similarly sensitive speaker, Volti Razz. It's a wonderful match. Gives me everything I want and desire.
