I own and might recommend the Tascam DR-680d. The downside for your specs above would be the mic preamps themselves in terms of the noise floor. I have zero issues running them without an external pre-amp, BUT, if I have my way I typically use externals before the 680. Others, and some on here, have claimed the noise floor is poor with the stock pres. You could always ask OADE's what they think and/or have on hand to sell you. That is where I bought my Marantz PMD-661 from. ( I am not rec'ing the Marantz as Dsatz gave a scathingly bad review regarding its' preamps, however, it does have the XLR and no internal mics stocking out feature you mention)
