Topping Pre90 Switching op amps?

@yyzsantabarbara 

I had volume issues with my McIntosh MC152 until I changed to the lower input voltage of the RCAs. I left the outputs on XLR and it worked fine. My problem is that it seems to render roughly half of my recordings worse than my regular preamp, a Hegel P30.

Yes. It was a digression, but interesting nonetheless. My question is on op amps, not amps.

Did the tube buffer reduce the transparency by a noticeable amount? The idea of a tube buffer occurred to me but I thought it would necessarily add some haze given tube equipment generally has higher s/n ratios.

Does the pre90 remote work well on yours. Mine, as reported by others in reviews, works poorly. I wonder if this issue has been fixed in newer production models.

@rrboogie 

What model infrared repeater do you use?

@rrboogie I look forward to hear your impressions of the Yaquin with the Pre90.

I did notice that the s/n ratio is listed at greater than 75db for the Yaquin. It seems it may be too noisy for the super quiet Pre90.

Thanks for the update. I found myself consistently preferring the way more expensive Hegel p20 and p30 so the pre90 will eventually go up for sale.
