New Integrated amp recommendation

Greetings:

I’m looking to upgrade my Yamaha 801 to drive my Revel 328s

Unfortunately I live in South Carolina and auditioning equipment requires a fair amount of time and travel. 
The room is 20x25 loft open to one side to a staircase and 11 foot ceilings (not ideal but limited amount of conditioning will follow) 

Almost always classic rock and contemporary jazz never above 80db Vinyl/CD and streaming

I’ve read a number outstanding reviews on Luxman integrateds and that is the first question..Is the 505z a good fit? If so does stretching the budget to the 507z offer a sonic difference? If not Luxman any other recommendations. I’m not necessarily looking to color the sound of the Revels but the Yamaha and maybe the room lack a bit of low end clarity and maybe a bit of fatigue from the Be tweeters.

Finally has anyone had experience buying direct from Japan? Can I assume the transformer is going to add unwanted noise?

Appreciate any thoughts love the forum. Learn from it everyday.

Thank you

JF

Here are Stereophile measurements from the 228Be that likely has similar specs to your speakers, and given this I’d want more juice than the 505z can provide…


My estimate of the F228Be’s voltage sensitivity was 89.1dB/2.83V/m, slightly below the specified 90dB/2.83V/m but within the margin of error. The impedance magnitude remains below 8 ohms for the entire midrange and bass, with minimum values of 3.42 ohms at 98Hz and 3.55 ohms at 290Hz (fig.1). There is also a demanding combination of 5 ohms magnitude and 39.5° electrical phase angle at 390Hz. While its nominal impedance is specified as 8 ohms, the Performa F228Be would work best with an amplifier that’s comfortable driving 4 ohm loads.

Given what you’re looking for I was also gonna recommend you look at the Coda CSiB and saw this used one available, which if I were you I’d strongly consider.  Hope this helps, and best of luck.
