Are there any bad D/A converters on the market?

This years marks 15 that I've been doing music. Either as a artist, producer, or engineer. In the past decade I've got to use and hear many different pieces of gear. Last week I purchased an Antelope Orion 32. After being impressed by the d/a conversion I got to thinking..... When was the last time I heard a "bad" d/a converter? By bad I mean unpleasing to the ear. I feel that d/a converters in my opinion (like mics and mic pres) have very subtle differences once you reach a certain quality. Of course some d/a converters sound better than others, but all of the ones I've heard from low budget interfaces to high end converters hasn't been a mile difference between them. My first interface was a m-audio delta 1010LT. I'd love to hear how it compares to converters today. How much of a difference would I hear?

Over the years I've been impressed by d/a converters on inexpensive products. My cousin brought over his silver avid mbox and I remember thinking wow, this sounds pretty good. M-audio interfaces has been sub par in the past to me, but the converters on the profire 2626 sounded really good. Even my $300 monitor station V2 from Presonus has a damn good d/a in it for the money. Though it doesn't sound as good as my lynx Aurora (it is close though!) I would be perfectly fine doing a mix on it. Don't get me wrong, d/a is important, (if it wasn't I wouldn't of bought an Orion 32) but I think d/a converters have came to a point where they all sound good enough to work on. With being said I ask..... Are there any d/a converters that sound bad?

Perfect Mic Pre and Mic Combibations

When you pair the right mic, with the right mic pre, with the right voice or instrument, you can hear it immediately. You will have the closest thing ever to the "perfect sound", and you will likely say one word once the sound comes through the monitors.......DAMN! It has happened to me a few times so I want to share the great combinations I have found that has worked for me.

1. Avalon 737 + U87 + vocal = This mic pre and mic combo is a bit cliche but this was first time I had one of those "ah ha!" moments when tracking vocals. I heard a lot about the Avalon 737 and how it was widely used in hip-hop. So I decided to rent one for an upcoming session. Paired with the U87 on vocals I couldn't believe how clean and clear my vocals were. Loved this so much I rented the Avalon for every session until the completion of the album. 
2. API 312 + Bock 195 + piano = I don't track piano's a lot but had to for a gospel song I did few years ago. I can't remember what mics I use to use on piano but after using the Bock it doesn't matter anymore. This combo with the  right mic placement (I used them as a  stereo spaced pair) and you can't go wrong. 
3. Empirical Labs Mike-e + Miktek CV4 = I've known the guys at Miktek for a while and couldn't wait to use one of their mics. When I found out one of the studios I use had just the CV4 no matter who I was recording next it was going up in the booth. Paired with my beloved mike-e I got the most crystal clear vocal recording I have ever done. The vocals sat just right and needed little eq when it came time to mix. 
4. Rupert Neve 511 pre + Miktek C7 + vocal. This been my go to vocal chain for over a year now. Simply sounds great.
