Considering one of these two Pre amps

I would appreciate input from all who have used these. They both seem to be very good for the price. Would like to know if there is much difference between them.

Thank you

I have experience with both. I would recomend the isa first as it will sound better on more sources in my experience. What kind of music are you recording?

Another inexpensive mic preamp to check out is the GAP Pre-73

I just went through this same process, as I wanted a pre for vox and as a bass DI. I ended up with the Warm Audio WA 12.  I have been very impressed with it.  Nice fully dimensional vox and a great bass DI.

Thanks for the assistance. I'm just looking for a good front end. Ideally I want to also get an outboard compressor and an EQ. I am beginning to spend more time on the recording phase to try and get the sound I want on the way in. I think having a few good front end pieces is better than relying on plugins. I'm leaning towards the solo 610 right now but I 'm in no hurry so I'm going to try and pick what may work for me. There's just so much to choose from.
 
Tom, You could sure say the same thing about plugins. Just think if you had as much outboard gear as you do plugins. I think were relying on plugins too much quite frankly. We shouldn't get lazy. Regardless of what gear I have I still try to get the best possible capture on the way in. There is obviously many variables to capture an instrument regardless of the gear but a good piece of kit can't hurt none.
 
Seven450, I checked out the WA12, looks pretty good.

I'll keep this in mind. I write different styles but not sure why styles would matter.

Those are both nice pres.  I've got the ISA One and it is a nice, professional preamp.  A lot of people call it sterile and it doesn't saturate like some other transformer-based pres,  but does have a lot of clean gain and a nice round tone.  It works well if you have a bunch of interface pres.
 
Either of the above should work well and a step up above interface pres.  The Solo, esp., can put a little fur on a recording.  Some good buys these days are the Warm audio stuff - Api-style pre and the Tonebeast, with is the same but with switchable op amps and transformers.  My favorite is the Rupert Neve Designs pres, but they are a bit more expensive, though I've never tried their single channel pre, which is priced somewhere between the two you are looking at.

Like Markhaskin post this is the kind feedback I'm looking for. Those with experience with these units.
 
Thanks all.

As with mics, there's an overwhelming number of pre-amp choices.
Try to narrow the focus by defining the "character" (or lack thereof) you're wanting from the pre-amp.
 
The Solo 610 has a warm/soft character.
It's not particularly aggressive sounding.
I had one for years... but (for this reason) it was rarely used.
Neve preamps (and clones) always sounded "better" (more aggressive) to my ears.
In particular, there's an articulation on transients that my other pre-amps lacked.
Everyone's aesthetic taste is different.  The Solo 610 may be exactly what you're looking for.

Thanks jim, I don't have any high end mic's meaning in the same price range or higher as these pre's but I am hoping to pull the better out of the mic's I have with a good front end. These are the mic's I have right now. I will at some point invest in a higher end mic for sure.
Rode NT1A, Octava 319, MXLv67, MXL V63M, AT4040, MXLR40 Ribbon and a couple of Sure 57's and 58's.
As far as a mic pre's go, I tend to record more ballad or rock ballad type music than screeming guitar and vocals stuff so wondering if a softer sounding pre is more suited for me. I guess that's why Markhaskin asked what type of music I record. Makes sense.
So for mellower music a more softer saturated sounding pre is better?
For more harder music a cleaner higher volume pre is better?
This kind info may steer me in the right directing.

both of those are excellent choices.
 
have you considered any 500 series preamps?
 

I'd like to check them out. Can you provide a link?
 Are the 500 series modules?

These are some 500 series examples. Basically, you buy a box that handles some number of 500 series items then you buy the items. The box can be like $500 and the modules tend to be between a couple of hundred and 1000.
 
This holds 2 500 series cards.

This holds 6 cards

This one holds 8 cards (I think it doesn't come with the power supply)

This is a pretty similar idea to https://seventhcircleaudio.com/ idea. The difference is that you can save some money by doing some soldering yourself with the seventh circle approach.
 
Really, if you are going to get 8 nice Pres in a 2U space, you're going to spend a chunk of change.
 
Both are modular and can grow.
 
The 500 series items have been criticized by some, but they are pretty interchangeable and practical.
 
Both allow you to grow over years. Like 1 Preamp a year for 8 years? Makes sense to me.
 
How cool to say you've made them yourself. That just gets you loads of cred!

The 500 series and the seventhcircleaudio stuff looks like it's the smart way to go if you do this for a living.
 
I'm thinking my Saffire Pro 24 has a couple of clean pre's. I also have the Presonus D8 which I think sounds different than the Saffire so something like the 610 will give me something different than those two thus having more options. Am I correct that the 610 is much different than the D8 and Saffire pre's?
 
Choosing a pre amp is not as easy as I thought it would be.

I journeyed the "which pre amp" jungle for a few years. I tried, bought and sold a few. I liked a lot of them, but not really satisfied. Finally, I found what I was looking for in a Neve 511.
 
I also own and really like the ISA One. The ISA One's sound and versatility to use as a 2 channel input when you use both the instrument di with the mic pre simultaneously is a big plus. More options than most pre's especially at their current pricing. 
 
Front End Audio has a "Rack Attack" deal that's interesting. You get a discount on a 2-slot Bento Power Rack when you purchase a 500-series module from them. The deal works out to looks like this example: 511 Neve ($545) + Bento Rack ($139) = $684 (If only buying one 500 module, you may also want to also pick up a blank 500 cover panel for the empty slot for a few dollars).

With this package, you would end up with an extra slot for adding whatever the need might be (compressor, eq, pre amp...) The Bento Rack allows you to push a button on the back to automatically rout the modules together for eq or compressor modules.
