So what are the amps?

I believe you since I owned and used a rebuilt pair of Stromberg-Carlson amps from the 40's that were better than many, many $5-8K modern amps I compared them to.  The only reason I ever sold them was because I needed more power when I went to the RM 40's.

George,

I do not want to reveal which brand yet because I am still looking for the preamp and perharp one more amp to complete my ultimate system.   The Bent is a great passive preamp but one of its weakness is the ultimate bass slam.  I am hoping to get this one preamp and combining it with the Bent to have the perfomance I am looking for at reasonable cost.

A few people at AC already know what I have so it is not a complete secret.

yeah, this seemed to be the case when Jon L brought his Bent over for me to hear in my system.

This is a result of a mismatch on either the source or amp side because the S&B 102s in the context of the right system are nothing but transparent.

yes, the bent was hella transparent and sounded awesome but didn't have the same dynamics and slam in bass as active preamps.

Mad Dog,

I will be getting Glenn's active Placette (thank you Glenn) and trying it in my system against the Bent.  To be fair, I will need to use some adapters in order to connect to the Placette (all my current ic's and balanced versions of VH Audio Pulsars), but otherwise it will be apples to apples.

The amps I will be using are Rowland 201's and McCormack DNA-500 (which I should have middle to end of next week).

This is true to some extent.  However, unless the source was specifically designed to have extremely low output impedance or in another word very high drive capability, the Bent will not be able to fix that.  For example, with very high gain amp such as the Ampzilla2000 (32 db), the bent will be able to put out very decent bass but not the ultimate.  With a low volume setting (thank to high gain of the amp), the power transfer ratio between the output of a typical source such as CD player will improved (especially for low frequency).  However, the Bent will not be able to make the output impedance of this CD player looks like a 10 ohms output impedance of a good solid state preamp such as the IRD LLC.

There are limitation to a transformer at low frequency.  This was one of the reason why very few tube amp has the bass slam of a good solid state amp.

Don't get me wrong, the Bent is the best preamp I have heard to date for overall performance.  Most people should be very happy with its performance accross the audio spectrum.  However, I am looking for some thing that has the mid and high of the Bent and at least the bass slam of the IRD LLC.  

The one preamp that I am looking for does not have every thing either.  However, I am confident that can combine it with the Bent to give me the performance I am looking for.

That very much depends on the transformer and is ultiamtely a function of the transformer's primary inductance.

While many speaker level output transformers may have a -3dB at as high as 10-20Hz, a good line level input or output transformer will have a -3dB well below 1Hz.

yes, this is true, too. i found Jon L's Bent to be extremely satisfying. the comments about bass were really nit-pick issues that i wouldn't have noticed if i hadn't directly a/b compared to something else...

Good post Rooze

I have wanted to try a couple of digital amps my self, your story is very good advice...try before you buy, and don't sell the old amp untill your sure the new one is better!

I am doing the exact opposite by bringing in a good old fashioned solid state amp (McCormack DNA-500) to compare to a digital amp (Jeff Rowland 201's).

Should be interesting...
