Help recommend a good tube preamp


I am looking for recommendations for a good, fully balanced tube preamp (< $4k - $12k) for my system:

DAC: Holo May

Power amp: Hegel H30 (input impedance (balanced / XLR) = 25k ohms)

Speakers: Focal Maestro Utopia III

Room: 20ft X 21ft

Music: mostly jazz / classical. Some classic rock.

Preamps tried before: McIntosh C2600, Hegel P30, Holo Serene, Rogue RP5

Constraints: output impedance should not be high (as my amplifier’s input impedance is quite low)

I tried C2600 (but with different amp / speakers).

Recently, I tried Rogue RP5 - sounded great but it does not have XLR out (H30’s unbalanced input impedance is a measly 9.6 kilo ohms). So, a natural recommendation would be the Rogue Audio RP7 - except that in the Stereophile review’s measurements section, John Atkinson recommends not using the pre with amps with less than 30k input impedance (affects low frequency response).

 

Thanks.

@reg19 I also had a Rogue RP-7, which has balanced in and out, and it is a very nice preamp especially considering its price. But it's not in the same league as the Backert Rhythm.

@markmuse Thanks. I see the Backert recommendations here. Intriguing. However, apparently, my DAC sounds better in a balanced setup. Also, my amp's balanced inputs sound better than the unbalanced ones.

C2700 Is a very feature rich preamp. I have one and after tube roll it's one of the best I've tried for the money. 

@reg19 The Backert Rhythm 1.3 is fully balanced, XLR in and out. That is what I use.

 

Might take a look at the Bryston BP 17 cube. balanced impedance is 4.5kΩ. 

@jbuhl That is very high output impedance - too high for me to use

I just realized that is listed as input impedance.  Output is not listed :/
