I am asking for a friend he has several high efficient speakers 92 to 94 dh speakers with a primaluna prologue amp... I heard that high efficient sparklers don't like thick cables. Is that true.

Thick or thin, solid core or multi-stranded, I don't see any particular trend as to what works with tube gear and higher efficiency speakers. I own speakers that are 99 db/w efficient and I run them with either a 6 watt parallel single-ended 2a3 amp or a 5 watt pushpull 349 amp. I have used fairly thick NBS speaker wires that work well with my setup. I've heard these wires in other, completely different, solid state, setups and it has the same basic characteristics (on the warmer side). I currently run Audionote Sogon silver litz speaker wires (multi-stranded) and these are even better (MUCH more expensive). All of the Audionote cables (designed for low-powered tube amps) utilize litz configuration with either copper or silver as the conductor.
A local dealer, which sells tube gear exclusively and higher efficiency speakers likes the cables from Snake River Audio. I have no idea about the construction of the cables; I do know that they work well with the kind of gear this dealer sells.
I had a Primaluna amp and used Kimber 8PR cables 13ft runs with my 92db De Capos. I did use them in a bi-wire config (5/3 3 to the tweeter).
I have 20ft runs from my tube amp to my 95db speakers.

I pondered whether or not the OP should consider the moderate-cost level Wireworld Luna 16/4 bulk cable, but stuck to the notion of a more old-school solid core copper option. However, I would actually suggest the Wireworld Luna 16/4. The Wireworld flat ribbon cable design seems to provide the best of what solid core wire tends to offer, while avoiding the deleterious effects of a conventional stranded conductor, among other things. Since I've explored the sonic benefits of Wireworld's DNA Helix cable geometry, I like it more and more with the test of time. I suggest one carefully select the choice of connector(s) for the Wireworld bulk length cables for optimized performance. I would suggest solder-termination of the Luna with Xhadow Reference Spades as an option to consider.See link:

I know when I got mine, I mentioned that I was using the Monster compression connectors. I know they're not Shadows but they seem to sound okay on a budget.

I'm sure your connectors function well, it's just that I tend to terminate moderate-cost level cables with premium connectors in order to get the best out of them. Splurging on premium connectors is one of the benefits of building a DIY cable with inexpensive but high performance bulk length cable. Spending just as much or even more for connectors as on a bulk length cable for a DIY project is not so unusual these days.
you were close by to do my terminations properly, I'd have cooked you a great meal and I'd have better connectors. :)

If one wants to create a solder-free termination, another approach is to use a gold plated copper crimp sleeve, which does not require a high-pressure, heavy duty, expensive crimping tool like that of an ordinary crimp-type connector. The soft copper crimp sleeve simply needs to completely cover the stripped wire, then a trough is made along the length of the crimp sleeve with a basic, inexpensive crimping tool. Then, the crimp sleeve is placed into the entry point of a dual set-screw type connector, the set-screws are then tightened enough to gouge into the crimp sleeve which creates indentations which secure the connector very firmly. This type of termination creates a modular connector, since one size spade can be swapped-out for another size spade, or a banana can be swapped-out with a spade or vice versa. This type of modular termination was hugely appreciated when I replaced a power amplifier with a different size binding post. It only took a few minutes to replace the spades with the new size, with no loss of performance as a result.
I'll see if I can find some.

remember, sometimes it depends on the length of the wire. You are concerned with many things, one of which is total resistance. But for short runs there is rarely a problem there.
AudioQuest Type 4 speaker cable is respected for tube amplifiers with high efficiency loudspeakers.
Audio Advisor offers a discounted, no frills, in-house terminated version.

I'm not sure what you call thick cables, but I've run Silverline Sonata 3s (94db) and Gallante Buckinghams (100db) with various cables and it seems they and I preferred Analysis Plus Oval 8 cables which have a fair amount of metal in the despite being hollow in the middle. My experience has been more metal = deeper bass.
