Krell HTS 7.1 for 2 channel or a new or used 2 channel pre?

@jfondell - I sent you a PM.  I don't know if you got it.

Oh, I just had another thought.  You may want to work on taming those tweeters first before thinking about changing toslink cables.  In my experience, the higher end toslink cables will make your mids/highs stronger, which could be worse in your current situation.

Ok, I have been so sick the past few days sorry for the late response, I think ill wait a while for the interconnects as they are a lot more than i was thinking...I may do the speaker cables 1st and see if that helps my tweeters settle down. What do you think?

Like I said earlier, putting in some 12awg stranded OFC copper speaker wire will really back off on the tweeter/highs.  It's so cheap and it's an excellent sounding interim solution.  Don't look at buying speaker cable in the $100-200 range.  They are not always great and the terminations (spades/bananas) can sometimes take away sound quality.  You can eventually upgrade to something like Neotech NES-3002.

I just got my HTS 7.1 back from Krell for a few replacement caps.  They also updated the firmware from 2.0 to 3.7 for free (they didn't even tell me they were doing it!).  After having it for a few months, then losing it for 6 weeks, I can say it's a beast of a unit!  It's perfect for my needs.  I listen to a ton of records still.  And this unit is so clean, it sounds like I upgraded my phono preamp.  All video source components run directly into my Samsung 4k LED and then out to the Krell via a TosLink cable.  And everything works in either DD 5.1 or DTS 5.1 (assuming it's being broadcast of course).  I have an Oppo 205 for all of my music and for Blu-Ray movies.  I use the Oppo's DAC out the 5.1 analog outs, into Krell's 7.1 channel input. For 2 channel music, the Oppo's balanced outs into the Krell's "Pre(amp)" mode.  I have used a Marantz AV7005 since it came out (4-5 years ago?).  And even though it's a decent unit for sound quality, the Krell trounces all over it in every way.  Those DACs are pretty solid, like the above user said.  But they still can't compete with Oppo's brand new DACs.  I did a lot of A/B'ing this weekend and I was hoping the Krell would win.  It's just too weak in bass and more shrill in the highs when cranked up (very livable if I didn't know any differently).  But the only time I use the Krell DACs are for my Sat Box, TV Apps and Xbox One S.  I always calibrate manually.  I don't care for what auto-EQ's do for the sound.  It's always jacked up and unnatural sounding.  My room is well treated with sound panels anyway.  The only tricky part I had was getting the OSD to work with a brank new 4k TV.  I had to buy an analog to digital video converter (coax to HDMI).  It was pretty cheap and does the job.  Anyway, the HTS is still a relevant unit even after all these years.
