Looking for something that has excellent SQ and imaging.

I would like to make a list of units for HT bypass.

So far the only I know of is the Parasound 2100.

Can you add to the list...?

There are a ton of preamps with HT bypass but only two that have HT bypass and analog bass management for two channel with a subwoofer pass through as well. Those are:

Parasound 2100
Parasound P7

Kal Rubinson had a nice review of the P7 in stereophile in a recent issue.

Absence of evidence is not evidence of absence

There was a thread on this very subject a while back. If I recall B&K also made a 2 ch preamp with bass management. Another alternative is to buy a very high quality electronic x over - you will have much more flexibility in choosing x-over freq, gain, slopes etc.

If you don't mind an integrated amp, the NAD M3 fits the bill.

You can get a Velodyne SMS-1 for $399 these days. This has an 80Hz crossover as well as a measurement/EQ system for the sub.

Of course, another approach is to get a sub that will take 2channel preamp inputs/outputs and add the necessary HP/LP functions. These are still pretty common these days (Velodyne, SVS, etc...) but they do require relatively long interconnects depending on where you position the components and sub.

This is the thread EC mentioned above. It's very informative with lots of amp and preamp with HT bypass choices.

I did think of that Kal, too many subs to play that game though.... I have 2 SMS's though, but I'm crossing my subs at 100hz

I think I my just go overboard, and get an all in one unit instead like the D2v so I don't have to piece meal or cobble everything together, I am a simple person and I don't mind spending the money to make my life easier. Ive had enough drama in my life already.....

Heck my kid cost me 1/2 million in the first 90 days of his life.. whats a couple grand at this point...

But the D2V2 will not give you anywhere near the 2 channel capability of a good 2 channel pre-amp.

Thats what I wonder myself. Heck my $600 parasound 2100 blew my $1300 yamaha receiver out of the water in 2ch. Warps budget is quite a bit larger than mine so a higher quality 2ch pre should be even better I would think.

But then he's back to figuring out what to do about the subs

Have you A/B'd the D2 or D2v with any 2 channel equipment?

I am pretty confident that it will surely be far better then what I am running now, and I'm not a 2 channel audio purist so any increase would be welcome. From the comments I have gathered from other users they seem to feel it offers phenomenal SQ....

A big factor to consider is the ability of Anthem Room Correction which, in many cases, is such an advantage that subtle differences in transparency become less than moot.

Agreed.... I have been thinking about that as well. If I have a HT bypass setup I would lose all room correction with any other setup, and the benefits of having ARC running would be for 2 channel for me then not...

You can have either with the push of a button.

How do you guys think the avm 50 would fare in the above scenario? I have the arc benefit but not the high quality dac's of the d2v.... I'm debating on getting a separate preamp as warp was debating and I need the sub output as well. I have an old paradigm x30 crossover laying around that I could use for the sub management and keep in The analog domain. My jl f112 could remove at least one low freq peak.
