1 EQUIPMENT REPORT HER REICHERT Rogue uio RP-1 PREMPLIFIER Pulitze Pize winning poet May Olive famously emake, attention without feeling... is only a epot. fte nealy two yeas of pattling fo Steeophile, I am finally gasping the full veacity of that statement. When I ea eviews that jabbe on about highs, meiums, an lows, an that ely exclusively on nonmusical vocabulay, I come away with feelings of acute cognitive issonance. Not to mention: if a eview has a lot of initialisms DD, S/PDIF, DXD, HDMI, etc. my DHD kicks in an I stop eaing by the thi paagaph. The best auio systems inspie the listene to eflect, Wow! That was nice! I pefe equipment epots in which the eviewe conceals the ientity of the component being eviewe behin esciptions of the music he o she was listening to though that component. I believe the most impotant thing an auio component can o is isappea into the one-song-afteanothe matix of the eviewe s jouney. (Di you hea that guita solo?) When wonous music finishes playing, the best auio systems inspie the listene to eflect, afte a long silence, Wow! That was nice! Theefoe, I ty to choose components fo eview that I hope will contibute to an immesive, sensual, time-melting sense of ebb an flow. My main auio goal is always astonishment. If I become stesse o etache, look out then comes the angy eview. ut if I become locke on, amaze, excite, it might be because I m investigating something eally fun such as the fist stanalone peamplifie I ve eviewe. My vey fist eview fo Steeophile was of Rogue uio s Sphinx hybi integate amplifie. 1 Since that fateful, fotunate ay pehaps because of it I ve been owning in a sea of integate amplifies. My supeios knew not how I longe to un with the big ogs an eview some high-quality sepaates.

Desciption Rogue uio s RP-1 tube peamplifie ($1695) is mae in the US. It has no DC, but it oes have a big alance knob, an a moving-magnet/moving-coil phono stage with ajustable gain an catige loaing. The choices of phono gain ae 45 (MM) an 60 (MC). The choices of esistive loaing ae multituinous: 30, 50, 75, 100, 230, 300, 1k, an 47k ohms. These options can be selecte by emoving the RP-1 s top panel an moving two slies (gain) an two DIP switches (esistive loaing). The gain povie by the RP-1 s line stage is 9.5.

2 ROGUE UDIO RP-1 simple, timeless esign that shoul look elegant 20 yeas fom now. t the left is that big, beautiful alance knob. (When was the last time you saw one of those?) Push this knob to tun on the supemely eaable OLED isplay, then tun it to isplay the Left/Right balance in elative, in lettes so big I coul ea them fom acoss the oom. esies being easy on the eyes, the isplay always inicates the volume level an the input selecte. etween the alance knob an the isplay is a lage, fim-acting Powe button. To the isplay s ight is a 1 4 " (6.35mm) heaphone jack, an a Volume knob that matches my belove alance knob. The hybi heaphone amplifie is iven off the output of the RP-1 s two 12U7 (o ECC82) tubes. The voltage is then oppe via a voltage ivie an sent to a small solistate powe amp. The output impeance is about 8 ohms, which, accoing to Rogue uio foune Mak O ien, is sufficient fo most typical ynamic heaphones. The plastic emote contol can be use to ajust the volume an balance, select inputs, an Mute the RP-1 s output. I lost the emote the fist ay. When I foun it, I igge it with a stap an safety-pinne it to my shitsleeve like an iiot mitten. Poblem solve. Listening: with the Fist Watt J2 powe amplifie Seeking sonic an musical complexity, I began my peamp jouney with music by Louis Thomas Hain, aka Moonog. The combination of Rogue RP-1, Fist Watt J2 powe amplifie ($4000, eview in pogess), an Technics S- C700 speakes ($1700/pai) gave me the cleanest winow yet on my ol pal, The Viking of Sixth venue (2 UK LPs, Honest Jon s Recos HJRLP18). Moonog wote hunes of compositions fo ozens of unusual instuments in no fewe than 27 tempos, an I o believe the time-keeping capabilities of this moest Rogue-anchoe hi-fi showe me at least 23 of them. Someay I ll own eveything Moonog ecoe, but fo now, Technics SL1200GE tuntable an Otofon s M2 lack catige though the RP-1 s MM phono stage mae Viking soun as I neve hea it. With this system, Moonog s compositions wee ovetly theeimensional, soli, an moe noticeably meloic than eve befoe. The nea-hype-imensionality seeme not the esult of phase anomalies, but eal an copoeal an tangible in a way that showcase Moonog s atistic intentions. Moonog s compositions an the ecoings theeof ae soun collages. How the iniviual instumental o ambient tacks combine spatially (as in multimono left/ight an up/own imaging) is a big pat of the compose s intene expeience. In many selections, the iniviual tacks seem to be lai out in squaes efine by the vetical an hoizontal axes of a wall-size gi, the soun of each tack spewing fowa into thee-imensional space fom its unique position on the gi. Though this system, bass tacks emege in an especially electable manne, with the illusion of ense waves stating low, nea the floo, then billowing out an ising. The RP-1 s winow on all this was so clean that I coul speculate about the types of micophone an ecoe use fo seveal of the tacks I ientifie on the gi. My finest Moonog expeience eve , who 4? n what 4? I on t know! The best auio systems o not simply eveal o e-ceate: to be engaging an satisfying in a musically meaningful way, they must show me some of the physical enegy matix that went own on the ay the eco was pouce. They must give me something to feel with my boy that communicates the attitues of the atists. Obviously, the tansuces the catige an speakes play majo oles in geneating this enegy matix, but of nealy equal impotance ae the lowlevel signal amplifies. If the fist stages of signal gain lose the kick, pesence, o stuctue of a ecoing, all the amp an speake can o is make that failue moe obvious. Think of the auio system as a boy, an the peamplifie as a glan poucing homones that contol the vitality, stength, gene, an attactiveness of the musical pesentation. To me, a well-engineee peamp is essential in peseving the music s physicality. Unlike most peamps, the Rogue RP-1 i not evisceate the music. s eco followe eco, I became gleefully awae of just how consistently the Rogue RP-1 was peseving the stength an expessiveness of whateve musical gene I playe. MOVING-COIL: fte installing the new Hana by Excel EL MESUREMENTS Imeasue the Rogue uio RP-1 s electical pefomance with my uio Pecision SYS2722 system (see the Januay 2008 s We See It, Fig.1 Rogue uio RP-1, phono input, RI eo (left channel blue, ight e) (1/vetical iv.). Hz The RP-1 s phono input appeas to use ulta-low-noise LT1115 op-amp chips. I left the intenal settings as use by Heb Reichet fo his auitioning high gain an a 300 ohm loa which esulte in a voltage gain of 65.1 at the main outputs with the volume contol set to its maximum, an 55.2 at the fixe output jacks. This is a little lowe than the specifie 60 fo moving-coil catiges, but the shotfall will be ue in pat to the Ohm s law inteaction between the uio Pecision s 20 ohm output impeance an the RP-1 s phono-stage input impeance of 298 ohms, this figue consistent acoss the auioban. I examine the phono stage s pefomance at the fixe jacks. It peseve absolute polaity an offee elatively high signal/noise atios: 58 (unweighte, wieban), 60 (22Hz 22kHz), an 69.8 (-weighte), all ef. 1kHz, 500µV, an measue with the inputs shote to goun. The RI eo is shown in fig.1. While the left channel (blue tace) offes an essentially pefect esponse, othe than the slight olloff in the vey low bass ( 3 at 14Hz), the ight channel (e tace) shelves own in the teble by 0.5. This is pobably ue to a slightly out-of-spec passive component. Channel sepaation (not shown) was excellent, at >70 below 1.5kHz, R L, an >80 20Hz 20kHz, L R. The phono-stage oveloa magin was supeb, at >31 fom 20Hz to 20kHz, steeophile.com Q ugust

3 ROGUE UDIO RP-1 low-output MC catige (see my eview elsewhee this issue) an setting the Rogue RP-1 s phono stage to high gain an a 300 ohm loa, I chose Ravel s Piano Conceto in D Majo fo the Left Han with my new favoite Ravel specialist, Samson Fançois ( ), an né Cluytens conucting the Ocheste e la Société es Concets u Consevatoie e Pais (LP, EMI C ). Like Moonog, Ravel employe jazz hamonies, an fequent changes of tempo an key signatue. This unusual conceto, one of only two compose by Ravel, pemiee in 1932 an is istinctive in many aspects (ie, it has only a single movement, an the piano is playe with only the left han). The conceto begins with what some at its pemiee must have thought was the ochesta tuning up. y the time Fançois hammes own his fist notes, the auience s collective min was pobably confuse an eliious. The piano soun on this ecoing is ak, heavy, an extaoinaily ense, but the RP-1 s MC stage an the Hana EL helpe a lot by igging own to the composition s coe intentions an letting the poweful eep bass, apily shifting momentums, an high-enegy highs voice thei ma Paisian countepoint with stupefying luciity. Tubes to the ea: look insie the RP-1. [long pause] Wow! That was nice! Listening: with the PimaLuna PoLogue Pemium ny slight yness I might have sense with the 25Wpc Fist Watt J2 isappeae when I insete PimaLuna s 36Wpc, push-pull, EL34-tube PoLogue Pemium ($2199; eview on the way). Suenly, thee was moistue on the face of my Kool-i pitche an ewops on tumpets an tombones. The wo liqui escibes the effect this peampamp combination ha on the music s movement an flavos. The Rogue RP-1 an Fist Watt J2 wee all about aticulation an joyous fowa momentum. In contast, the combination of Rogue an PimaLuna iecte my attention below the music s suface: to the obscue ey cuents an hythmic ipties that enhance music s coe excitements.

The gain with the contol set to its maximum, 60, was 9.9, left channel, 9.6, ight, measue at the main out jacks, an 12.8 at the heaphone output jack. Thee was no gain at the fixe output jacks.

With exactly that thought, I playe Volume Two of the music compose by my ustalian fien J.G. Thilwell fo The Ventue os.
