TRL Dude Dilemna

Based on all the high praise for the TRL Dude preamp here and other sites, I took a chance and bought one from a local A-goner to see if it could displace an Air Tight ATC-2 preamp currently in my system. The two amps I currently use are a McIntosh MC-402 and Viva 845 SET Monos. It turns out that the Dude is not compatible with either amps due to an impedance mismatch. So I only got to hear the Dude in a compromised performance mode.
I was not quite wanting to give up on the Dude yet given everyone else's enthusiasm about its performance. I am considering the Samson monos as a natural match. I can convince myself that the Samson's could be better than the MC402..My real issue is that I would have to give up the Vivas. Not sure I can make the leap that a solid state amp will satisfy me as much as those SET Vivas. Then there is the leap of faith that I cannot hear the Samsons with purchasing them....
Has anyone replaced their SET amp with Samsons and remained satisfied with the decision? My speakers are the Green Mountain Audio Continuum 3 which are about 90db efficient with an impedance 6.5 Ohms, +/- 0.75 Ohms 150Hz to 20kHz. Thanks for your input..

Tellefsen,
The Viva 845 is an excellent sounding amp, being tubed I would think The input impedance is rather high(50k or higher) and should work with the Dude.
I used the Dude linestage in my system recently and it worked well with my 300b SET amplifier.I`d be very hesitant to let the Viva go.

I would not sell two good amps just to justify the purchase of a preamp. I would not think the Sampson's are capable of matching the SET sound of your Viva 845.

Sell the Dude and consider buying the Aesthetix Calypso listed. Spend $400 on the right NOS tubes and you are set.

Charles1Dad,
The Viva's have an input transformer, and while the designer would not tell me the input impedance...he did say that a pre-amp with a high output impedance would not work well.

I am located in Dallas. I do get to the Baltimore area frequently.

Tellefsen,
Well if that`s the case it comes down to Viva amp or the Dude. Since you own this wonderful amp I`d search for another preamp. I`ll admit a bias toward superb SET amplifiers compared to SS amps.
Good Luck,

Purchase the new GT160 mono blocks from TRL and be done! They're a smaller version of the GT200 and much less expensive...in line with the Samsons.
